Accelerated video output with ffmpeg2theora 0.24
When I converted two files with ffmpeg2theora their duration changed shorter - they seem to play back with accelerated speed. When I play one of them with VLC, the video stops at 99 seconds but audio continues until 170 seconds. The other file is 120 seconds long but it is played back in 80 seconds.
Here is ffmpeg2theora output:

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 bugs ?
Hi,
we are using ffmpeg2theora as encoder for a new
project.
We are finding problems during the conversion step
with different type of input compression but, for now,
in AVI container.
In many case an error generated by ffmpeg lib produce
a stop in theora lib (we suppose)
Here an example:

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

ffmpeg2theora start and end time support
For last few days I was trying to learn ffmpeg and libtheora API. In the 
process, I have modified ffmpeg2theora code to include support for start 
time and end time.
ffmpeg2theora -s 60 -e 130 file.avi
will produce file.ogg which will be from 60th to 130th second of input 
file (something like -ss and -endpos in mencoder). This is a useful 
feature for someone who wants to cut a part of video

optimization of theora contract job
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

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: issue converting from a png image list
Hi Jan, all
I am trying to generate a video introduction with a fade-in / fade-out
effect. To do this with ffmpeg2theora only, I generated a list of PNG
images: img001.png, img002.png... img299.png
The ffmpeg2theora man page says:

Is there something like qt-faststart for theora?
One thing I noticed though when reading about ffmpeg to make the h.264 
was that for internet, you could use qt-faststart to move some stuff (I 
think called MOOV) to the front of the file allowing the file to start 
playing before it was finished downloading.
That certainly helps quite a bit, I was wondering if there is a similar 
type of thing for theora? Theora files I host do not seem to
