ffmpeg2theora 0.24 regression ----------------------------- Note: this issue was fixed by adding "--inputfps 25 -F 25" to ffmpeg2theora. According to Keith Richie, who proposed this workaround: "This is an all too common error with ffmpeg not correctly identifying the input fps." ------------------------------------------------------------------------------------------ Here's another problem I have with the 0.24 version of ffmpeg2theora. When I try to convert a h264 file to theora... (Note that for size and runtime reasons, foo.mts is a truncated file, I just took the first 32MB of the original file) ffmpeg2theora-0.24.linux32.bin foo.mts -x 1280 -y 720 -o foo-ffmpeg2theora-0.24.ogv Input #0, mpegts, from 'foo.mts': Duration: 00:00:15.83, start: 1.000067, bitrate: 16946 kb/s Program 1 Stream #0.0[0x1011]: Video: h264, yuv420p, 1920x1080 [PAR 1:1 DAR 16:9], 50 tbr, 90k tbn, 50 tbc Stream #0.1[0x1100]: Audio: ac3, 48000 Hz, stereo, s16, 256 kb/s Pixel Aspect Ratio: 1.00/1 Frame Aspect Ratio: 1.78/1 Resize: 1920x1080 => 1280x720 0:00:07.79 audio: 82kbps video: 4254kbps, time remaining: 00:01:34 When I try to play the ogv file, the video stream is playing at accelerated speed, while the audio speed is the same as in the original. Same issue with version 0.24-svn20090716.
