720p mkv video playback

unfortunately i can't confirm this. i am running on 3.2 stock rom and neither google nor mx player are able to play x.264 encoded 720p mkv files smoothly. which is a shame, since even my 2 year old smartphone can do this with a single core cpu. is it maybe the container format (mkv) that causes the problems?

and how are chances that a future rom update might add 1080p high profile support?

thanks!
[Acer Iconia A500] WereCatf:
I haven't tried .mkv files on my tablet, so it could be that. I can only suggest you to try with Dice Player instead or using .mp4. I'll try to remember check .mkv compatibility myself, but I've been sleeping like crap lately and I'm rather too cranky right now to bother with it now, sorry.

AFAIK it's a hardware-issue, and if it is a H/W issue then a future firmware update won't be able to fix that. I am not entirely certain it is a H/W issue, but I think I read it on NVIDIA's site. Gotta check that, too, some day.
[Acer Iconia A500] uli68:
ok, in case you want to investigate further, here's an example file from one of my favorite tv shows,which the a500 struggles to play smoothly. sound is also completely off (mx video player 1.4):

http://www.imgden.com/1109/Spartacus.Gods.of.the.Arena.Part06.720p.HDTV.x264-IMMERSE.mkv.jpg

well, i had no high hopes the tablet could really cope with high quality 1080p material but it would be great to have at least smooth playback of 720p tv show rips.

has anyone already tried video performance with a custom rom like the thor rom? would be interesting to see whether codec support and general speed improves...
[Acer Iconia A500] joeshmoe1:
Does anyone know how the presets on the first page would translate to command line? I have handbrake installed on an unraid box but don't have access to a GUI. I gather from reading the handbrake forums that the preset files can't be used from the command line so I'm trying to figure out the actual command.
[Acer Iconia A500] joeshmoe1:
I got it figured out. I opened the preset file in handbrake on a windows machine and then used query editor to generate the command.

Enable the query editor – Tools > Options > Advanced Tab . Check the box ‘enable query editor’ > Close. restart

Make sure you use the file you plan on converting to generate the query. On my first attempt I used a mkv with no chapters and then transcoded a file with chapters resulting in the output of a file containing just the credits:o. You will also need to edit the path for the input and output if you're running the query on another computer. Here's an example of 720p high-profile with an .mkv (24 chapters) as input.

HandBrakeCLI -i "/PATH/FILENAME.mkv" -t 1 -c 1-24 -o "/PATH/FILENAME.m4v" -f mp4 -w 1280 --loose-anamorphic -e x264 -q 20 -a 1 -E faac -6 dpl2 -R Auto -B 160 -D 0.0 -x subq=6:mixed-refs=0:weightb=0:trellis=1:me=umh:b-adapt=2 --verbose=1

Thanks for the presets WereCatf.
[Acer Iconia A500] WereCatf:

[Acer Iconia A500] yaworski:
I've encoded a 720p video using high-profile imported from file provided in the first post in this thread. When I play this file using Acer Media or MX Player (ARMv7 installed) it's not being played well (MX Player shows it uses HW decoder).

When I play the same file using BSPlayer (with ARMv7 VFP installed) it looks and plays good.

I haven't tried Dice Player yet as it is paid app.

I have also made some tests with mkv files. I've used a file endoded using Handbrake (the same as above) and repacked it into mkv container using mkvmerge. It is just a container change, as both video and audio streams are just copied into new container.

The results are:

- Acer Media doesn't see the file (as expected),

- MX Player plays file but forces the use software decoder (hw is not available for selection),

- BSPlayer doesn't give much difference and plays the video exactly the same way it plays it in mp4 container.

---edit---

I've installed DicePlayer Trial and Tegra2 plugin from Market and it has the same problems with playing my prepared files as MX Player (with the exception it plays both mp4 and mkv in hw, but both are laggy and there is a lot of skips).

DVD to Iconia

Correct me if I am wrong, but it is pointless to encode your video file to 720p from a DVD source... All you will do is get blocks and artifacting as the transcoder tries to make up for the source.

DVD format is 720x480p (480p)...

Now, if your source is Blueray, then, yes, use the 720 and 1080 profiles, but, for DVD's I just don't see it.

Can you add a dvd profile to your post if you agree?, or, am I wrong?

I do like your post and give you kudos for posting it the way you did.

I messed with video way back when using cinema craft encoder and doing manual setup compressing formats to make SVCD's from DVD sources, back before blank dvd's were cheap.. SVCD's used a 480x480 format..
[Acer Iconia A500] WereCatf:
Aye, true enough. That has been a total brainfart on my end, gonna add a DVD-source preset there now!

Thanks for noticing, though!

Hello,

New here been struggling with this a500 vid deal

Used your dvd settings and it plays great on pc 1.76 g for the new pirates.

This is strange must be something simple i am not seeing.

Used the dvd source settings above.

File is 1.7 gb and plays on pc after handbrake is done looks great!

I transfer to micro sd 32g and it wont open error message same thing on a500?

What causes this when copied to micro sd?

Did it earlier on the special features disc with other settings and it works 407mb?

:cool:Is it the size?

Im so close to this any help would be greatly appreciated.

[Acer Iconia A500] Ping192:
Thanks! I was looking for something like that!
[Acer Iconia A500] WereCatf:
If I understand you correctly, the file does not play anymore after you've copied it to the microSD card without doing anything at all otherwise to it.

Well, if that's the case then either you have a faulty microSD card or you've bought a fake card and it's actually 1 gigabyte one and that breaks the video. In either case you should replace the card.

hd player for a500

Don't know if this is the right thread or not but I installed

MoboPlayer v1.2.155.apk (free download) and now I can play .avi .wmv.mp4.

with no problems. does not require any recoding or anything. Just install app and any movies I put on 16gb stick. will play.

hope this helps
[Acer Iconia A500] WereCatf:
Entirely different thing, mate. First of all, try playing 1080p video and you'll definitely see jerky video. Secondly, try putting a 30GB BluRay movie on your 16GB stick without transcoding. Good luck with that.

The point with transcoding is to make sure that the video in question fits on the device and that it plays using H/W acceleration so the battery lasts longer, and that's what this thread is about. Not about which video player to use.
[Acer Iconia A500] godaro:
maybe you didn't stumble upon a high profile mkv ... yet

anyway, I gave up re-encoding, it takes too long with my resources. its is preferable to re-download from other sources a properly encoded HD material, or switch to Standard Definition video material

when I encoded my personal footage, I already preferred to use default settings in handbrake and now I am happy to run it smoothly on my Iconia

IMO, re-encoding is the solution of last resort.
[Acer Iconia A500] WereCatf:
I am now designing a transcoding suite of my own, with several improvements and twists over the current solutions. I do not however know how long it would take me to implement one as I haven't been coding anything of that scale for several years, or shall I just set up a project and work as an administrator for it, telling where to go and what to do, and hope others will provide the code.

Just a quick observation while I was temporarily running the ICS leak for a couple days back.

No need to handbrake your high profile 720p BRRips anymore, as it played everything I threw at it flawlessy in the stock player.

Something to look forward to when Acer finally releases it OTA. :)

Test Video

I've run several files through Handbrake - all originally 1080 material.

I have used all of the 720 presets made available on this thread (baseline and high, both big and smaller files).

My results are bad. In each case I end up with a file, copied to my Class 10 card, which drop lots of frames and skips.

The videos play fine on my PC but are unworkable on the tablet.

Is there a largish sample file I can download somewhere to test if it is me, handbrake or my device?

I've tested the SD card - it is Class 10 and is 32GB - so that isn't the problem.

I'm using the paid version of MX Player with the codecs downloaded and installed.

The machine is completely stock.

Appreciate the help; we'd like to use the tablet for movies on the plane with the kids while taking a trip soon; right now we're better off just installing Angry Birds for them and not having a movie avalable. I'd like to fix that.

[Acer Iconia A500] godaro:
Hello Andy,

Do you have problems only with the 720p material encoded by yourself in Handbrake? did you try other HD material from other sources to compare?

What about Standard Definition material? does it play ok on your machine ?
[Acer Iconia A500] AndyInNYC:
I'm looking for a high def source (properly encoded) from another source - ie not something I've used handbrake on.

Standard def plays fine.

Any videos out there I can download as a test to see if it's me or the tablet?

[Acer Iconia A500] AndyInNYC:
still unsure

Werecatf,

Thanks for the clip. Unfortunately, since the clip itself has no sound and has lots of animated bouncing going on I can't tell if the playback is correct or not.

I can't seem to sync the startup with a playback on my PC - and even if I could I don't have lizard-like eyes to track both at the same time.

While it looks good, it does seem as though frames may be being dropped.

Do you have any live action, with sound clips? I noticed on my attempts that the sync was so far out because the film wasn't viewing at its correct speed. The frames on the screen were beautiful, but not all of them were showing.

That's my fear on your posted clip, but I can't tell since it isn't 'people' and I'm not familiar with how it should look.

Hope your arm is feeling better and I won't make any 'punny' remarks given your signature.

[Acer Iconia A500] AndyInNYC:
The Beaver played perfectly.

Is it possible that Handbrake doesn't like source files which otherwise play perfectly?

I may just need to restart with original material and not transcode already converted files.

Thanks for the material - at least some of the pieces have been added back into the puzzle.

Andrew
[Acer Iconia A500] WereCatf:
^ I'm sorry, but I really do not know. That Beaver-clip was also done with Handbrake and my 720p high-profile preset, so I am at a loss as to what your problem is.

Did you check the audio was properly downmixed to stereo? Surround audio causes frame-dropping, sync-issues and all kinds of hassles on A500 so it could possibly be that.

Thanks for the presets and instructions!

I have two issues:

The presets I downloaded from the thread didn't have all of the settings listed in your instructions after importing them in to Handbrake. I re-entered them manually and then saved the preset and it's fine. I'm just not sure if it's something I did though.

A movie I just re-encoded using the high profile 720p preset has some serious stutters in a couple of relatively high motion scenes. Would re-encoded with baseline help, and would re-muxing/re-indexing help or is that something that's essentialy accomplished during the re-encode.

[Acer Iconia A500] godaro:

[Acer Iconia A500] pinmemo:
it can play 720p, proved by downloading a bunch of YOUTUBE 720p vids and they can be played flawlessly, even with the stock player.

did try again, the baseline profile seems to work with a lag at every 20 mins or so. but i should be able to play high-profile right?
[Acer Iconia A500] godaro:
not "every" high profile content. very aggressively encoded 720p material (too many reference frames >4; weighted p-frames or very high bitrates) cannot be handled properly by Tegra2. Stick to the settings described here and you will be fine

give it a try do dice player. i think it is marginally better than mx and other players which I compared.

Werecatf or anyone else, I have mainly DVD movies that had already been converted (xvid, dvix, avi). Can I use handbrake to convert them to mp4 so that I can put them on my Acer a500? If so could you maybe post what settings I should use? I would greatly appreciate it. I was thinking of using your baseline-profile but just thought I should ask first. I'm using the mobo player.
[Acer Iconia A500] Valkillmore:
MX player should play those files (avi, divx, xvid) fine, even up to multi-channel audio DivXHD.

You may need to install the ARM codec for MX (specifically built for the Tegra) as well, but it will let you know if needed.

I have never been able to get Mobo player with anything. I would suggest trying another player first, before diving into hours upon days upon weeks of unnecessary encoding.

They are from 720p MKV rips of Blu Rays. I was wondering because on my Android phone the video fits the screen perfectly.
