Divx playback problem

[navyguy]

Warning: kind of a long post.

I see several other threads that appear to be the same problem as what I'm having now that I can actually get Divx files to play. But no solutions in them that work for me.

The movie starts and after 3-5 minutes, depending on the individual file, the movie stops and I'm back at the file selection screen on the MVP. This is a graceful exit, no crash on the PC or on the MVP just the movie playback ends abruptly. Also no windows eventlog messages.

As other's have mentioned, using a different codec will have an effect on how long the movie plays (divx5 codec from divx.com will run for at least 15 minutes, I couldn't take watching with the A/V synch problem longer than that ) however only ffdshow playsback without an A/V synch problem (approx. 10 second audio delay with divx5). Turning on or off ffdshow options (resize, noise, sharpen, etc.) has no effect on how long the movie plays.

I've tried this with gbpvr .91.12b, .91.11 and have just downloaded .91.08 to try it out. Used ffdshow 20041012 sse2, 20041012 regular. Used Hauppauge 2.4.23104, 2.4.23038, 2.2.22146. All of these experience the same problem at the same points in the movie playback depending on the specific movie file.

I've attached the logs in their entirety but I'll paste the important parts here. The interesting thing to note in them is that transcoding ends 1:13 before the movie playback stops:

gbpvr.exe.log
5/8/2005 9:48:17 PM.812 VERBOSE [35] Request 200000 bytes (file size:137758724 file location: 137600000)
5/8/2005 9:48:17 PM.812 VERBOSE [35] about to check

trans2mvp.exe-native.log
21:43:53.000 VERBOSE transcode processing started
21:47:04.781 VERBOSE transcode processing complete

Note: at 9:47:04 in the gbpvr.exe.log nothing is reported that is different than what has been logged or continues to be logged until the last entry above except that the file size stops growing at the 137758724 mark. This movie is over 2 hours long so there is no way it is actually completing the entire transcoding in just over 3 minutes.

In other threads about this problem it is theorized that the PC isn't fast enough to do real-time transcoding and the playback is over-running the transcode file thus 'crashing'. For this problem at least that can't be the problem as the movie continues playback from the transcode buffer for over a minute after the trans2mvp process exits. This playback time after the 'crash' varies depending on the individual movie file (I'm assuming compression, resolution, audio bitrate differences) but the semi-common denominator is a transcode file size of approx 130000000-140000000 when it stops growing and the trans2mvp.exe stops.

I hope I've given enough info to maybe help track down what is happening. Hopefully someone will have an idea or two to try out or better yet a solution. I'll provide whatever info I can if more is needed.

Thanks!

Try the attached Trans2MVP.exe. It adds an additional message to the log to say what event code triggered the completion of transcoding. It may give some clues.

Here is the logfile generated by the new trans2mvp.exe.
What could be causing the abort?
Thanks for the help Sub!

OK, well it thinks the transcoding has completed because one of the filters has returned EC_ERRORABORT. Unfortunately I dont know anyway to help you narrow down which filter is doing this for you.

[navyguy]

Ok thanks for the help Sub, I wish we could figure out what was going on with those files.

However on a better note, I decided to try and remove encoding errors or the like from the equation so I encoded a movie myself and that file is working just fine so far. Up to 30 minutes and still playing so the moral of this story is don't trust the encoding on downloaded files

However since the files played normally on 3 other players I have access to (WMP10, DivX player that comes with the DivX5 codec, and the Hauppauge software) it does seem that the trans2mvp is a bit touchy on what it can deal with. Any way to make that more robust in regards to problems such as I was experiencing or have you done all you can do since you're trying to interface with a bunch of 3rd party software?

Once again thanks for the help!
