AVC decoding errors in VLC 1.1.2

Postby DGMurdockIII » 06 Aug 2010 05:49

The current VLC Media Player 1.1.2 seems to produce slight issues decoding x264 video encoded using the "medium" preset (according to the report, not for "fast" or "slow" preset), as reported in the german doom9/Gleitz board (find an attached file there - VLC 1.0.3 shows no problems, VLC 1.1.2 shows garbage above the "Saturday" titling). Currently my best guess is an issue with a combination of encoding options which is only present in the "medium" preset of x264.


P.S.: http://sourceforge.net/projects/mplayer-win32/files/ -- mplayer of today doesn't show any issues, possibly either already fixed in libavcodec, or caused by a VLC specific relation between splitter and decoder.

Sorry but without a sample of a non working file this report is useless. And I can't reproduce it.
And we need to know all of the settings which have been used for the encoding, the preset alone is not enough.

The test sample was attached in the german thread in »Reply #4« - DGMurdockIII just forgot to post the copy of the doom9 board thread including the link to the german thread. It also lists the verbose MediaInfo analysis (including the whole x264 options set).

So, were you able to download the sample and reproduce the problem?

Yes and we also found some other samples showing problems so the team is working on a fix.
