h264 in f4v: non monotonically increasing dts

[cesareof]

I have an mp4 file that was pulled off a Flash Media Encoding Server that was post processed with f4vpp.exe and I am trying to do a straight codec copy to seperate the audio stream from the video stream and I can't seem to get it to work with newer builds of ffmpeg.

I have an older build of ffmpeg (2008-09-24) that works but I want to use a newer build because I am unhappy with the quality of video that this build produces. Was looking for any advice on what might be the best way to do this:

This command line:

d:\ffmpeg.NEW.exe -i d:\Testing\MovieConversionIssue\Issue.mp4 
-vcodec copy -an d:\Testing\MovieConversionIssue\videostream.mp4 2> d:\Testing\MovieConversionIssue\out.txt

Produces this output:

And a videostream.mp4 that is only 34kb and is not a playable video stream.

Please provide the sample and / or the revision that introduced the regression.

I have the *.mp4 clip that causes the issue indicated in this ticket, but that movie file is 6mb and the Maximum Upload is 2.5MB(Way Too small, but probably regulated by PHP), is there another way I can pass a sample mp4 your way for testing.

I don't know when this issue exactly began because I don't religously keep my ffmpeg version updated, I can give you an ffmpeg version in which this file is properly transcoded (the resulting mp4 looks terrible).

This command line:

d:\ffmpeg.WORKS.exe -i d:\Testing\MovieConversionIssue\Issue.mp4 -vcodec copy -an d:\Testing\MovieConversionIssue\videostream.mp4 2> out.txt

Replying to cesareof:

I have the *.mp4 clip that causes the issue indicated in this ticket, but that movie file is 6mb

Consider reading http://ffmpeg.org/bugreports.html (you may ignore the limit there for A/V sync issues) or upload to  http://www.datafilehost.com/

[cesareof]

I uploaded the file to upload.ffmpeg.org\upload and I uploaded the same movie to datafilehost:  http://www.datafilehost.com/download-12423221.html

[cehoyos]

The svn version you tested allowed you to write invalid files (with non monotonically increasing dts), so I don't think this counts as a regression.
