[Vibrant Q&A, Help & Troubleshooting] m3rb:
I've searched thoroughly on this and no solutions, only a few other users reporting the same problem.

Got a TV, Blu-ray player, or network media player that supports DLNA? Can you record a video on your Vibrant, and successfully play it on your client device? I think I saw someone say they had success using a WD Live HD Plus...but I'd sure like to get confirmation before I go get one.

I picked up a Samsung BD-C6900 player that ought to do this. Getting the networking set up on both the phone and the blu-ray went extremely smoothly. The Avatar trailer plays over DLNA perfectly. But videos recorded with the phone's camera? No go. They play for a second or two, then freeze, then sometimes pick up again, much farther into the clip, then freeze again. Even on the smallest resolution.

The C6900 is going back, unless I get some satisfaction from level three support in the morning...by the time I got that far tonight, the department had closed for the day.

So maybe I try the WD, or wait until some future time when Samsung finally gets around to doing the engineering that should have been done before releasing product, and spreading hype about Allshare that crosses the fine line from fraud into marketing.

Any other experiences or ideas?

Update 10/1/2010 5PM MT:

Amie at level 3 support did not have any solutions, but was conscientious in taking down the data to relay to development.

I discovered that turning off "record audio" results in videos that play through allshare correctly, excepting the highest resolution mode. Even though they play correctly, there is a notice at the beginning: "Audio codec not support". This notice also sometimes briefly appears at the start of the malfunctioning videos that do contain audio.

I've copied the videos over to Ubuntu and used mplayer -identify to start analyzing them. Nothing jumps out as suspicious. In both cases, the audio format ID is 255 and mplayer selects the FAAD AAC codec. Mplayer plays them all fine.

I tried Twonky Mobile Server in addition to allshare, and it behaved similarly to allshare. It produced a log file in which the most interesting difference between avatar_trailer and the recorded videos is that DLNA profiles were found for the malfunctioning videos, but no profile was found for the Avatar trailer.

I wonder if something is triggering on-the-fly transcoding to happen, even though it should not be needed? On-the-fly transcoding is something that can happen under DLNA, so that broader compatibility can be achieved. It's going to be slow, though, on these embedded processors. Slowness due to transcoding would be consistent with the symptoms. I don't know whether such transcoding would happen on the server end (phone in this case), or the client end. Anyone, anyone? Bueller?

My next experiment will be to burn the videos to disc and see what the C6900 does with them in that case.

Update 10/1/2010 10PM MT: All the videos play fine when burned to disc. So it's purely an allshare issue...but is it on the phone end, or the BD player end? I checked back and found the source of the report that the WD Live worked with DLNA from a Vibrant...but it was not claimed that videos recored using the Vibrant's camera worked. So I have never seen any report of anyone ever playing their Vibrant-recorded videos using DLNA/allshare. Seems like something amiss on the phone end, then...but why, if the video files themselves are OK, do two different DLNA server apps (allshare and Twonky) both fail in the same way?

Next experiment: stream to Windows 7 as the DLNA client.

I would like to capture the DLNA streams, but am not sure how to go about that.

Mods: I see you moved this to Q&A. I think perhaps it would be a better fit in Development, now?
