#21 MPEG-2 decoder crash (with 2+ threads)

MPlayer (86)


With the latest build (r28126) the MPEG-2 decoder will produce crazy corrupted output when using 2 or more threads. In SMPlayer it will even crash. And it will crash the hard way: Windows "application has crashed" dialog, NO crash info in MPlayer's log! From the console it won't crash, but the output is totally corrupted. Tested with various MPEG-2 files.

    Screenshot of distorted output

  • same problem with mpeg1

    aditionaly when I try to play my mpeg file (see: crash on corrupt mpeg1+others bug) with threads then mplayer only crash when I play two (or more) files eg:
    >mplayer.exe 1.mpeg 1.mpeg copyof1.mpeg
    without lavdopts=threads=2 mplayer always crash on first file

    offtop: dirac not play on mplayer (signal 11 in decode_video) and is not decodable by ffmpeg (hard crash to windows)
