1.4 vTap (WM, Symbian, BlackBerry)

vTap is an RSS-like content syndication service with integrated, multi-site searching (including all major video sites, WikiPedia etc.) It has both a standalone (Windows Mobile / BlackBerry) client and a Web interface. The latter is of paramount importance with BlackBerry, as it’s, currently, the only way to access online YouTube videos.

First, let’s take a look at the standalone Windows Mobile client. After installing and starting, it presents you a single input field, where you can enter for example the video you’re looking for – as with the traditional YouTube search. It, however, also presents Wikipedia (and other video) hits.

(a Windows Mobile screenshot showing the collected results of a search – again, not only from YouTube)

Its GUI is pretty powerful as it allows for for example feedback, account login etc. Its settings capabilities are also pretty cool (1 2). Also allows for showing related videos which is pretty rare as of the writing of this article.

As far as the BlackBerry is concerned, the native client is only able to search from the Wiki as can be seen in HERE. The vTap folks do state the standalone client is, as with Windows Mobile, able to play videos (or, at least, pass videos to the system-level multimedia player) starting with BB OS version 4.3. This doesn’t seem to be the case with version 4.5[0.9] beta of the operating system (see the 04/23 update of THIS article for more info on acquiring and installing the beta). As can be seen in HERE, there’s no Play icon at all and the menu (screenshot HERE) is much less powerful than that on Windows Mobile. (These are all 4.2.1 BB 8800 screenshots; the client behaves in exactly the same way on the same device with the latest 4.5.0.9 beta OS). Some Pearl users with native 4.3, on the other hand, did state it worked for them.

See for example THIS for more info.

However, this isn’t a problem! There is, fortunately, a way to play back online, streamed content on the BlackBerry too. (Note that the following part has only been tested under 4.5.0.9. It might work on "official" 4.2 / 4.3 OS versions as well.)

1.4.1 The online Mobile vTap

If you navigate to http://m.vtap.com/ on your BlackBerry, you’re presented an interface pretty similar to that of Mobile YouTube. It allows for searching and a lot of other goodies. On BlackBerries, it’s the only way to get online, non-reconverted content, unlike the ways described for example HERE or in the well-known, related CrackBerry.com tutorial. Screenshots showing it in action – again, under OS version 4.5.0.9:
[General Topics] Menneisyys:
(note that, as with Symbian, I couldn’t make a shot of the rendered contents)

Note that Mobile vTap is also compatible with Symbian; in there, it uses the built-in RealOne player (and RTSP). It must also be compatible with HTC’s Streaming Media on Windows Mobile (haven’t tested this), should you want to prefer it to alternate solutions.

1.5 Operating-system specific, other apps

1.5.1 Windows Mobile

1.5.1.1 CorePlayer

I don’t think anyone needs to introduce CorePlayer (particularly not to readers that have been following my past multimedia-related articles), which has recently received native YouTube browsing / searching support – in addition to, of course, playing it back. And it does the latter extraordinary well. Being based on the fastest AVC (H.264) and HE-AAC decoders, it plays back high-quality (non-3GP) videos with much less overhead than any other YouTube client on Windows Mobile. See for example THIS and THIS post for more info on this.

If you know iPhone’s YouTube player, you already know that of CorePlayer – the latter is very similar to iPhone’s. (Except for, for example, the lack of related videos.) This means it’s very easy to use and, again, has the most CPU-efficient decoding algorithm when it comes to playing back quality AND firewall-friendly, H.264 + AAC content - as opposed to the low-quality RTSP-streamed and, therefore, not firewall-friendly, 3GP content, which has considerably lower demands and can be played back by even non-optimized code without major CPU hits. Some screenshots:

(standard list view)

(detailed view of a selected video)

It’s still worth explaining how you can switch between the RTSP + 3G (low/medium-quality) and H.264 (high-quality, firewall-friendly HTTP-streamed) modes. By default, CP is configured to use the former. If your network topology / connection doesn’t allow for RTSP connections, the current, 1.2.3 version doesn’t display any error message – just times out after some minutes. (This will be fixed in a future version, as is also explained by the developer: "Automate the YouTube Quality Control 'seeking'... this will help incase one setting appears to hang (spinning buffering icon).") If you either want to fix this problem or just want much better audio & video quality, just switch to "High Quality" in Menu > Tools > Preferences > Select Page > Network > YouTube Format:
[General Topics] Menneisyys:
Note that QTv Display is set by default as the video renderer; therefore, if you don’t see any video (only sound), you’ll need to set the video mode to Raw Framebuffer or, if your PDA has a graphics co-processor (for example, the Intel 2700G), to it in Menu > Tools > Preferences > Select Page > Video > Video output:

Note that with the (unfortunately, still very few) stereo high-quality (H.264) videos (like this) aren’t played back in stereo, unlike with TCPMP-based H.264 / FLV players - or simple 3GP players like that of Nokia Flash Lite 3 or the BlackBerry. This problem will be fixed really soon, as HE-AACv2, the state-of-the-art sound compression technology I’ve often elaborated on in my articles, finally gains support in CorePlayer in the near future. This is just great news – so far, Windows Mobile clearly lagged behind both Symbian S60 (on N-series devices) and BlackBerry 4.5 (which both support HE-AACv2 out of the box, with minimal CPU usage and AVRCP support not available with Windows Mobile) when it came to playing back HE-AACv2.

Also note that, while the YouTube client of CP currently lacks a lot of additional functionality like clip upload, login, online favorites etc., this will soon be fixed as is explained HERE: "we have omitted some features till later on when we add it as a module with login, uploading, related, and bookmarking".

Finally, should be interested in why I recommend CP so much, take a look at my H.264 Bible (if you haven’t already done so), where I’ve thoroughly benchmarked the H.264 (and AAC) decoding efficiency of all media players.

1.5.1.2 Milesmowbray’s YouTubePlay - YouTube Player

There’s another, free(!) and pretty cool, but, being based on the old TCPMP libraries, compared to CorePlayer, less efficient standalone player, Milesmowbray’s YouTubePlay available HERE.

(the search results, highlighting a clip - as you can see, there isn't much you can do - no related videos, flagging, account support and the like)

(it uses a built-in video player for playback - that is, it doesn't rely on external players)

It’s pretty straightforward to use as it’s a stand-alone app: you just install it and fire it up. No further (external) app installs are necessary. See the above-linked thread for user discussion & new versions (albeit, of course, I’ll try to keep you updated).

If you want a standalone (non-Web-based) app and don't want to pay for the, otherwise, technically superior CorePlayer, this app is worth checking out. Note that, however, it's pretty much inferior to CP, capabilities-wise.

1.5.1.3 YTPocket

YTPocket is a decent Web-based interface offering Flash-based, that is, high-quality (as opposed to low-bitrate and, hence, low-quality 3GP streams) and HTTP (meaning firewall-friendliness) streaming. The interface is pretty much similar to that of the Web interface of Mobile YouTube.

As it’s FLV-based, you must have a FLV-capable player to play the videos it downloads. Shouldn’t you already have TCPMP with the FLV plug-in installed, you can easily download them over-the-air from the setup tutorial page of YTPocket.

[General Topics] Menneisyys:
(a direct URL can also be entered – or, better, pasted – should you have received a direct link in, say, an e-mail and don’t want to fire up Nokia Web or Opera Mini to find out the title or other parameters of the clip to be able to quickly find it)

(you can also supply the YouTube ID – see the remarks of the previous screenshot)

Note that there used to be another Symbian app to play back YouTube, emTube, but it’s been down for some months and it’s still not known whether it’ll be restarted at all. Also see THIS.

Finally, the Symbian version of CorePlayer will receive the same functionality than the Windows Mobile version in 1-2 weeks (this being written on 04/24/2008). See section 1.5.1.1 for more info.

2. Comparison chart

The feature / comparison chart available HERE is pretty easy to understand based on the info above. It lists the compatibility, quality, protocol (whether it’s using high-quality, firewall-friendly HTTP / H.264 or the low-quality, firewall-unfriendly RTSP 3GP), standard YouTube features like uploading, editing / reading comments, related videos, logging into your account and the ability to save videos for future use (in which YTPocket really rocks).

3. Verdict - what to go for?

There're no hard-and-fast rules for choosing the right solution. First, you need to decide whether the quality (or the lack thereof) of 3GP streams are sufficient for you. If they aren't (and you aren't a BlackBerry user) OR you can't play back RTSP streams (because of your restricted network connection), go for something FLV / H.264-based. Fortunately, both Symbian and Windows Mobile has several apps offering FLV / H.264 playback. For WM, I recommend FlashVideoBundle and/or CorePlayer the most. For Symbian, Mobitubia is a really decent solution - and the forthcoming CorePlayer, if you don't mind the higher price tag. Of course, on Symbian, you can also safely stick with Flash Lite 3 if you have a compatible handset / firmware version (again, remember that Flash Lite 3 being comparatively new, your otherwise compatible phone may still running an older, incompatible firmware - as was the case with the Nokia N95 before firmware version v21).

On the other hand, if your connection isn't firewalled (which would make incoming RSTP connections impossible), the 3GP "quality" is sufficient for you and/or you must reduce network traffic (or, you are on the BlackBerry), you can safely stay with http://m.youtube.com/ (see section 1.2) if you're a Windows Mobile (making sure you do have an RTSP player (pre)installed; for example, the free HTC Streaming Media) or Symbian user or the online Mobile vTap (see section 1.4.1) if you're on BlackBerry.

UPDATE (04/25/2008 12:02PM CET): note that BlueApple.mobi is another great transcoding service compatible with, among other mobile platforms, the (4.3+) BlackBerry. See for example THIS for more info on its BB compatibility.

Also note that I may haven't included some other YouTube transcoder services in the Bible - there're quite a few of them, and I've found the reviewed ones the best.
[General Topics] volwrath:
I thought overall this was a good review. I would take exception on one thing.

You say: If you want a standalone (non-Web-based) app and don't want to pay for the, otherwise, technically superior CorePlayer, this app is worth checking out. Note that, however, it's pretty much inferior to CP, capabilities-wise.

I disagree if we are talking purely about youtube. YouTubePlay plays youtube videos much better than CP1.2.3 on a US 3G network. Sure CP's youtube integration is very nice with the favorites and most viewed etc, but when it comes to play the video you have to decide if you want to lower the resolution or watch it stuttering. Y2P works fine with little buffering using h264. It may work fine over Wifi, i havent been able to test that. Betaboy has said this should be fixed in the next milestone, and if it is, then yes, CP will be superior for youtube viewing. I hope thats the case , as I really do like the CP integration
[General Topics] Menneisyys:
Yup, many complain about the buffering issues with YouTube and CP; will definitely emphasize this in a future article update. (BTW, interestingly, here in Europe, I have no similar problems with Vodafone (using an unlimited data plan via HSDPA).)
[General Topics] Menneisyys:
4.3 3GP

Finally, 3GP, the worst of all – the format that you should avoid at any rate (unless you absolutely need to reduce data usage or don’t need video at all because it’s static like with, say, THIS clip) uses the resolution of 176*144 and a very low video bitrate resulting in a lot of blockiness. An example screenshot follows so that you can see how bad it is:

Note that, audio-wise, there’re two sub-formats of YouTube 3GP streams. The first (better) uses 22 kHz AAC mono audio and is referred to as “Medium-quality” by CorePlayer (as with FLV); the second (worse) uses the 8 kHz AMR speech vocoder to further decrease data usage (and to further reduce audio quality). Of course, the gain is marginal; therefore, if you absolutely need to go 3GP, try preferring the former format.

4.4 Setting the YouTube format in CorePlayer

Don’t forget to set the format in CorePlayer according to your needs and the restrictions of your handheld. (For example, as has already been explained, on a VGA device it’s always worth trying to use H.264 because of the higher source resolution. On a QVGA device, the difference isn’t that big - H.264 is a bit less blocky but, again, requires far more CPU cycles and has much higher data usage. Of course, you should also keep in mind the superior audio quality of the H.264-based streams too.)
[General Topics] TheChampJT:
Maybe not the best place to post here, but outside of the YouTube support, do you think CorePlayer is worth the money?
[General Topics] Menneisyys:
Depends on what you want to use it for and on which OS. For example, it can't be used for HE-AACv2 playback. If you wouldn't use for it but, say, general non-WMV (ASP, AVC etc) video playback, then, surely.
[General Topics] TheChampJT:
Great, thanks! Also, great work on all the "Bibles".

Audio with NO video???

Ok, I dont know if this is the correct thread to post but I'll start here...

I'm trying to play saved .flv video files from the storage card on my Hermes/TyTn.

I'm running a Hermes (8525) SuperCID with Schaps4.01

CE OS 5.2.1933 (Build 18533.0.7.0)

I've tried tcpmp.pocketpc.0.72RC1.cab,

TCPMPflvplugin-v0.4.2.CAB,

youtubeplay_1006.CAB

All with no luck. All I get is audio with NO video.

Any advice?

UPDATE (05/12/2008):

1. (Symbian):

a. I've tested the last about 20 latest featured videos on YouTube with MobiTubia. All played well. Therefore, it's possible it's only with some older videos that MobiTubia delivers sub-par results; with newer ones, it doesn't seem to.

The Symbian version of CorePlayer, on the other hand, doesn't seem to like firewalled cellular connections. These cause it not to download any clip lists. This works just great under Windows Mobile (and, of course, with MobiTubia under Symbian) and, therefore, must be an internal bug.

b. I've very thoroughly compared the power consumption of MobiTubia to CorePlayer 1.2.4. While MobiTubia consumes a tad more power when it's still loading (caching) the clip in the background, after the clip is cached, it delivers considerably better results (much lower power consumption) than CorePlayer. Therefore, it's always worth going for MobiTubia when your Internet connection speed is much faster than the ~320 kbps stream of FLV videos because, after the caching is finished, the power consumption will be really decreased. CorePlayer, on the other hand, doesn't cache the file and, consequently, it'll use the (with both Wi-Fi and 3G connections, power-hungry) wireless unit all the time.

The following screenshot shows this in effect: the first ~5:30 show CorePlayer playing back a 6-minute clip; the second show the latter with MobiTubia. As can clearly be seen, the latter manages to cache the file in the first about 60% of the total playback time of the clip; after this, it doesn't use the wirleess unit any more, resulting in a heavy power consumption decrease. CorePlayer, on the other hand, streams the YouTube contents all the time, resulting in much higher net power consumption:

I've made another screenshot showing CorePlayer only, repeatedly playing the same 6-minute clip. As can clearly be seen, the power consumption is constantly the same (high) because there's no caching at all.

Let's see some other screenshots comparing the power consumption using HSDPA. As you'll see, the difference won't be as articulated as with Wi-Fi and the average power consumption will be pretty similar because buffering, with much bigger excess power consumption, takes much more time than over Wi-Fi. The following shot shows playing the same clip thru Wi-Fi and, then, HSDPA using MobiTubia:

As can clearly be seen, the average power consumption is bigger because the system were in the low-power (~1.1W) area for a much shorter time than with Wi-Fi. (And, of course, streaming anything (!) via HSDPA will always take much more power than via Wi-Fi, as has also been explained in my Multiplatform Radio Stream Transcoding Bible.)

Let's see the CorePlayer results. Two HSDPA examples follow:
[General Topics] Menneisyys:
UPDATE (05/12/2008, later): I’ve forgotten to elaborate on the other implications of CorePlayer 1.2.4 having just received FLV support.

One of the most important consequences of this is that you no longer need to use TCPMP as a player together with FlashVideoBundle, should you want to stick to browsing the "full" YouTube in IEM and invoke an external player to play back the videos on them.

That is, you only need to install CorePlayer and, then, the single CAB file of FlashVideoBundle (as of this writing version 1.4.4) available for download HERE and, then (making sure you restart it at least once so that the plug-in is loaded), just fire up YouTube in your (WM5+) IEM and click any video link. In the context menu, just select “Play video” and CorePlayer will be invoked. Cool, eh? You’re no longer dependent on the aging TCPMP but can invoke CorePlayer to play your videos instead. One less programs to install on your handset, not to mention the other advantages (more refined, more battery-friendly drivers, decoders etc.)

If your handheld already has TCPMP pre-installed, you’ll want to either uninstall it or, in CorePlayer, override the file associations. Unfortunately, I couldn’t find out how you should force FlashVideoBundle to pass the execution to CorePlayer instead of TCPMP (without a chance to remove it) with ROM’s containing TCPMP built-in, without any way to uninstall them, like that of Ranju's HTC Universal ROM (v7.6). I’ve tried everything including deleting HKEY_LOCAL_MACHINE\ SOFTWARE\TCPMP in the Registry (the plug-in uses it) – in vain. Unfortunately, simply unassociating the files from inside TCPMP won’t work. I'll let you know when I find a solution.

Great points on the new Coreplayer. It is definitely operating much better.

One question I had that you might be able to answer is what does My Src and My Lists do in the youtube menu? I think my src may be my submitted videos but I dont have any. I do have some videos in quicklist, and they won't show up in My List.

Any ideas? and nice writeup btw

What is this about!
[LeEco Le Max 2 Guides, News, & Discussion] flauschi18:
This is a warning to all buyers of the Le Max 2 X821 sold by banggood in october / november 2018 with 4/64 GB!

They sold some sort of patchwork phone with bodies of X821 / X820 with suspectful having internals of X829.

Reason:

- Le Eco aka LeTV never build an X820/X821 (for the chinese or indian market) with 4/64 GB - the only model having this combination was the X829 for US

- LTE band 20 is not possible to connect (tested with several SIM cards)

- LTE band 20 cannot be activated (tested several firmwares)

Please test your device and report please!

Suggested app for testing: "Network Signal Guru" from playstore.

1. Root device

2. Start app

3. Grant root privileges to app

4. Tap three-dot-menu (upper right)

5. Select "Lock bands"

6. Select "LTE"

7. App shows usable bands

--> Please post results

Thanks!

I got the following bands for my "X821": 1,2,3,4,5,7,8,12 and 17 (20 is missing).

For comparison: On my bq M5 I got all bands usable in germany: 1,3,7 and 20 (800 MHz)

Are you referring to this: https://www.banggood.com/LeTV-LeEco...8.html?rmmds=search&ID=46149&cur_warehouse=CN ?

But if you scroll down to specs you'll see this:

4G: FDD-LTE: B1(2100)/B3(1800)/B7(2600)

TDD-LTE: B38(2600)/B39(1900)/B40(2300)/B41(2500)

I do not see B20 listed there.

Plus, Max 2 for $130 with 4/64 GB?

That should be a raised red flag, considering the fact that a year ago *real* X821 3/32 GB was selling for $180-190.

Can you return it? I would.

after checking:

1. there is no LTE band 20 in this phone (and yes, when I ordered the phone it had band 20 in the product specs, now removed)

2. only one sim slot is working!!!! NO DUAL SIM!!

3. the box is fake, including the sticker with a production date of 07/2018

4. the charger is only 2A charger compared to the original 3A charger of the X820/X821 I have

the rest of the phone specs are comparable to my other X821, the roms work. it just seems the screen is slightly different in quality. The phone is definitely fake, possibly from the same factory than the original.
