hi all as the input stream for the "encoder_example", it could give "YUV4MPEG2" file, can we use any other file type.....? insted of "YUV4MPEG2" file, i want to use "rawvideo" file , because i want to compare theora with xvid codec. so that i need to encode a video (same video) using both theora and xvid. but both these codecs does not operate on the same input file type (i am working with the example encoders provided with the package). please can anyone help...

I am using theora_encode along with ffmpeg: ffmpeg -an -s 1920x1080 -r 24 -i bigbuckbunny.mp4 -vcodec rawvideo \ -pix_fmt yuv420p -f rawvideo - 2>/dev/null \ | ffmpeg -an -f rawvideo -s 1920x1080 -r 24 -i - -f yuv4mpegpipe - 2>/dev/null \ |* theora_encode /dev/stdin 2>/dev/null *| ffmpeg -y -f ogg -i - \ -f mp4 -i bigbuckbunny.mp4 -map 0:0 -map 1:1 -vcodec copy \ -acodec libvorbis -ab 256000 -f ogg...

I wish to transcode an AVI from 29fps to 15fps theora. I have tried many combinations. The nearest I have so far is to: 1) ffmpeg -i input.avi -f avi -vcodec rawvideo -acodec pcm_s16le -r 15 -ar 22050 -ac 1 intermediate.avi then 2) ./ffmpeg2theora-0.15.linux.bin -f avi -c1 -H 22050 -o out.ogg intermediate.avi This gives me an output I want, however, the intermediate uncompressed stage generates 36Mb/sec of data, which is impractical. So it would be better...

Im using a customs processor to run ffmpeg on a video to create a thumbnail. So far so good. Except when I do: cmd = "-i #{@file.path} -f flv -s 320x240 ~/Downloads/foobar/q.flv" success = Paperclip.run(''ffmpeg'', cmd) Console is reporting: ffmpeg ''-i /var/folders/uL/uL0bYOOZEZaJH5E+BmDJVE+++TI/-Tmp-/stream, 16824,1.mpeg -f flv -s 320x240

Theora-devs: I am in seek of a theora (but possibly vorbis/ogg/ffmpeg) dev to optimize the encoding in a realtime software product. We do live encoding and transcode into ogg/theora/vorbis at various resolutions and frame rates. The higher resolutions cannot process in realtime and we are pushing the boundaries of hardware (cpu) encoding with the existing theora/ffmpeg. Right now we have to

Has anyone noticed this? I have a video made with Final Cut Pro, which I convert to .mov via Compressor. This .mov file plays back fine in Quicktime. But when I then use ffmpeg2theora to convert to ogv, the video seems to play back too fast compared to the audio (I'm using VLC 1.0.2, the latest I believe, to play back the ogv file, and I also have an app that uses the recently

Hi all, Xiph aims at developing open-standards media formats. Though xiph.org tells about vorbis/theora/flac/speex, nothing is mentioned about container to use (that is ogg/ogm). I have a few questions Is there a difference between ogg and ogm? I guess its only the extension that is different and everything else is same. Some tools (like ogmtools) are available to create ogm files. What is
