Hi First of all, thanks for your great software. It is first one who was able to play and recode properly my Sony camcorder files (crappy Sony AVCHD). I face small problem with other things, filled bugzilla entry, but noticed in other reports recommendation to send mail to maillist. Here is my problem: I have a file, where midentify will fail to detect correct parameters. I am not sure it will cause playback problems, but probably it will be nice to show proper result in midentify. I am using mplayer as tool to retrieve video/audio parameters from video files on my embedded box to make some kind of catalog. Tested on svn version of ffmpeg (to build shared libavcodec), and git version of mplayer and tested there. Also i test on latest ebuilds of mplayer on gentoo with x264 library enabled, it gives same results. mplayer with debug output from gentoo mplayer -vo null -ao null -frames 0 -identify -v /work/00001small.m2ts >/home/nuclear/x264_fail.txt http://www.nuclearcat.com/files/x264_fail.txt sample file (cut to 10Mbyte) http://www.nuclearcat.com/files/00001small.m2ts ffmpeg detecting file properly home distfiles # ffmpeg -v 9 -loglevel debug -i /work/00001small.m2ts FFmpeg version SVN-r20373, Copyright (c) 2000-2009 Fabrice Bellard, et al. built on Nov 3 2009 02:16:15 with gcc 4.3.3 configuration: --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64 --mandir=/usr/share/man --enable-static --enable-shared --cc=x86_64-pc-linux-gnu-gcc --disable-debug --disable-ffplay --disable-network --enable-libmp3lame --enable-libtheora --enable-libx264 --enable-libxvid --disable-indev=v4l --disable-indev=oss --disable-indev=jack --disable-outdev=oss --enable-x11grab --enable-libdirac --enable-libgsm --disable-vdpau --disable-vdpau --disable-altivec --cpu=core2 --enable-gpl --enable-version3 --enable-postproc --enable-avfilter --enable-avfilter-lavf --disable-stripping --enable-hardcoded-tables libavutil 50. 3. 0 / 50. 3. 0 libavcodec 52.37. 1 / 52.37. 1 libavformat 52.39. 2 / 52.39. 2 libavdevice 52. 2. 0 / 52. 2. 0 libavfilter 1. 4. 1 / 1. 4. 1 libswscale 0. 7. 1 / 0. 7. 1 libpostproc 51. 2. 0 / 51. 2. 0 [NULL @ 0x860720]Probed with size=2048 and score=100 [h264 @ 0x87ced0]no picture [mpegts @ 0x860720]MAX_READ_SIZE:5000000 reached Seems stream 0 codec frame rate differs from container frame rate: 47.95 (48000/1001) -> 23.98 (24000/1001) Input #0, mpegts, from '/work/00001small.m2ts': Duration: 00:00:03.12, start: 599.958311, bitrate: 26188 kb/s Program 1 Stream #0.0[0x1011], 1/90000: Video: h264, yuv420p, 1920x1080 [PAR 1:1 DAR 16:9], 1001/48000, 23.98 tbr, 90k tbn, 47.95 tbc Stream #0.1[0x1100](eng), 1/90000: Audio: truehd, 48000 Hz, 6 channels, s32 Stream #0.2[0x1100], 1/90000: Audio: ac3, 48000 Hz, 5.1, s16, 640 kb/s Stream #0.3[0x1101](rus), 1/90000: Audio: ac3, 48000 Hz, 5.1, s16, 384 kb/s Stream #0.4[0x1200](rus), 1/90000: Subtitle: pgssub Stream #0.5[0x1201](rus), 1/90000: Subtitle: pgssub If you need more information - let me know
