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:
D:\tmp\ffmpeg>ffmpeg -i f:\vi1.avi vo1.avi
ffmpeg version 0.4.9-pre1, build 4743, Copyright (c)

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

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 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)

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:
Encode a series of images:

That's exactly what I tried with the latest 0.24 release of ffmpeg2theora:

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

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

problems compiling R-0.63.3 on alpha
Hi again !
Thanks for the info on updating the config.site file which I
have done. I have also added -lm in the Makeconf manually
because this is needed explicitly for DEC cc.
However, there are still a few problems when linking some
of the files as you can see from the enclosed log.
Ciao,
Andreas
