ffmpeg2theora 0.25 synchronization issues when converting from .mov
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

Ogg checksum thingie needed
I need some sort of utility to calculate a checksum of an Ogg file. Two differently encoded Ogg:s should give different checksums, but the same file with different tags should give the same result. (The serial number doesn't work here, obviously. I need something that is changed if a bit of the file is lost.) -- Björn Lindström <bkhl@elektrubadur.se> http://bkhl.elektrubadur.se/

Piping AVI to ffmpeg2theora
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

ffmpeg2theora tool
I've been encoding with ffmpeg.exe. Due to the muxing issue, I tried ffmpeg2theora, but I ran into some issues 1. it fails on 1080p content. 1920x1080. 1920x800 is okay. 2.

So I need to do an additional step of muxing it into a
