Original thread: http://thread.gmane.org/gmane.comp.video.mplayer.user/64876 The unknown hardware produces files that contain H264 video, but can't be demuxed by lavf. The files may also contain audio (G726/G729), the DirectShow filter installer also contains an audio filter. ffmpeg -i E-20100925-233415.mp4 FFmpeg version SVN-r25591, Copyright (c) 2000-2010 the FFmpeg developers built on Oct 27 2010 23:24:31 with gcc 4.3.2 configuration: --cc=/usr/local/gcc-4.3.2/bin/gcc 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 [NULL @ 0x8b91560] Format detected only with low score of 24, misdetection possible!
