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...

...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 t...

...are unplayable (tried mplayer, vlc, and theora_play). I've built the alpha7 libtheora rpm (using the Fedora Core 6 SRPM) and installed it on Fedora Core 4 (my current system). (I use an older build of cinellera to edit the video and produce a linux quicktime movie with DV/PCM). If I use -v 5 theora_encode show bit rates in the 80-90kpbs range. By specifying -V 1800 I see bit rates that in the 7-30kbps range. lav2yuv in.mov | yuvdeinterlace | theora_encode -V 1800 in.wav - > out.ogg I also tried the statically built ffmpeg2theora and it exhibits the same problem. Executing ffmpeg2theora in.mov...

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

Hi, Is anyone able to help Mr Stoner? -Ivo ---------- Forwarded message ---------- From: Ed Stoner <ed@whsd.net> Date: Oct 9, 2007 5:32 PM Subject: [sugar] video encoding To: sugar@lists.laptop.org I would like to provide the functionality of a "video export" from within an activity I am working on.

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.
