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

...stream.yuv Any suggestions on how to improve this? In order to test I'm making available the LiVES video file (which is essentially a .tgz of the PNG images): http://lives.reimeika.ca/cvs/swath.lv1 To encode this you can download the LiVES theora encoder plugin: http://lives.reimeika.ca/cvs/theora_encoder.py and copy it into an empty directory (make sure it's executable). Move swath.lv1 into that same directory and run: ./theora_encoder.py -v -o swath.ogg -a 3 -t hi -L swath.lv1 This will create "swath.ogg". In order to see what the uncomporessed movie looks like you can run (in tha...

Hello, I use my system for time-shifting local TV and I usually re-encode the capture card's MPEG2 into theora to create much smaller files. However since upgrading from alpha 5 to alpha 7 I can no longer do this. The problem seems that the bit rates are too high and the resulting files are unplayable (tried mplayer, vlc, and theora_play). I've built the alpha7 libtheora rpm (using the

Hi, I would like to create a movie out of a lot of png files. Using mencode I would do have something similar to mencoder "mf://*.png" -mf type=png:fps=5 -vf spp,scale -ovc lavc -o output.avi but I want to have an ogg format. I.e. an ogg movie How to do it? convert can convert the pngs to an mpg but not to an ogg! convert: unable to open module file

ok now I see why we need another packet in the header. The first one is basically for ID purposes (theora_decode_header()). I've jammed my huffman trees in there but it sucks because I need them later on when I actually build the huffman tree structs (theora_decode_init, calls InitHuffmanSet()). At that point the original header packet is gone so I've been keeping it around in a buffer.
