New submission from Michael N. Pritula <prit...@yandex-team.ru>: I have file (attached) with mpeg1video and MPEG-1 Layer 2 audio. It plays well by VLC 1.1.4. It decoded well by FFmpeg svn revision 18021, but using r23285, r25413 and latest r25603 FFmpeg misinterprets input as psxstr with adpcm_xa audio stream, after transcoding there is only noise. $ ffmpeg -i mpeg1_mp2_regres FFmpeg version SVN-r25603, Copyright (c) 2000-2010 the FFmpeg developers built on Oct 29 2010 19:47:30 with gcc 4.1.2 20061115 (prerelease) (Debian 4.1.1-21) configuration: --cc='ccache gcc' --prefix=/home/pritula/wNewFfmpeg/package-root --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-version3 --disable-yasm --enable-libfaac --enable-libvorbis --enable-libtheora --enable-libxvid --enable-libx264 --enable-libschroedinger --disable-encoder=libschroedinger --enable-libgsm --enable-libnut --enable-gpl --enable-nonfree --enable-postproc --enable-pthreads --enable-avfilter --enable-shared --extra-cflags='-I/home/pritula/wNewFfmpeg/package-root/include -g' --extra-ldflags=-L/home/pritula/wNewFfmpeg/package-root/lib libavutil 50.32. 3 / 50.32. 3 libavcore 0. 9. 1 / 0. 9. 1 libavcodec 52.93. 0 / 52.93. 0 libavformat 52.84. 0 / 52.84. 0 libavdevice 52. 2. 2 / 52. 2. 2 libavfilter 1.53. 0 / 1.53. 0 libswscale 0.12. 0 / 0.12. 0 libpostproc 51. 2. 0 / 51. 2. 0 [psxstr @ 0x8069560] Invalid parameters 33 1 -1157562368 [psxstr @ 0x8069560] Invalid parameters 33 2305 -1157562368 [psxstr @ 0x8069560] Invalid parameters 33 4609 -1107230720 [psxstr @ 0x8069560] Invalid parameters 33 7169 -1107230720 ... a lot of similar messages ...
