lavf demuxer fails to autodetect EVO (HD-DVD) file format

[alain.perrot@…]

Hi,

I am using latest mplayer from SVN repository on my Linux x86_64 system.

It used to be able to play EVO files using the lavf demuxer, but on latest revisions, the lavf demuxer fails to autodetect their format.

For sample files, see for example the sample.evo and MAININTRO.EVO files from ​http://samples.mplayerhq.hu/evob/.

Using ffplay (from ffmpeg SVN repository), both video and audio are played.

Using mplayer's default demuxer, video can be played, but there is issue with EAC3 audio.

Using mplayer with lavf demuxer without specifying the format, none of video or audio are played:

$ mplayer -v -demuxer lavf MAININTRO.EVO

possibly related to the cache-size change reimar made?

[alain.perrot@…]

I took some time today to test different mplayer revisions.

I have finally found that mplayer revision 29120 works as expected (the lavf demuxer does autodetect the file format), while revision 29121 fails.

------------------------------------------------------------------------
r29121 | reimar | 2009-04-01 11:24:46 +0200 (mer 01 avr 2009) | 2 lines

Increase probe buffer size to 32kB, this makes ac3 auto-detection far more reliable.

------------------------------------------------------------------------

Reverting reimar's change in revision 29121 with an up-to-date revision of mplayer (r29176) solves the issue.
