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

ffmpeg2theora 0.24 regression: accelerated video output (converted from h264)
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)

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.)

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

Paperclip not executing FFMPEG properly
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:

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. I have raw yuv. in ffmpeg I use -s 1920x1080 to specify the source
size. ffmpeg2theora doesnt seem to have a way to accept width/height
for the raw yuv (420). So I need to do an additional step of muxing

ffmpeg2theora start and end time support - patch
After posting my previous mail, I realized that i should instead post a
patch against HEAD. This is because v0.12 was released while I was also
changing ffmpeg2theora.c from v0.11. So please use this patch instead and
apply it to version at http://svn.xiph.org/trunk/ffmpeg2theora
