libavcodec.so exposes 2 decoders for theora. An internal one and
Hi, about this file, it has been encoded with latest libtheora (1.1).
Regarding avcodec, do you know how can I tell it to use libtheora instead of
the internal?
Because looking into the sources I can only see one codec id defined:
Hi Reinhard,
I'm sorry to post again but this issue is affecting Ubuntu 9.10 32 bit as well.
On a clean virtual machine (so no strange things/configuration happening on it)
I just did the following:
sudo apt-get install g++ libavcodec-dev libavformat-dev libswscale-dev
Then I compiled the test
Update:
without recompiling the test executable (so it gets compiled against the
default Ubuntu libraries/shared objects), but using the latest shared objects
compiled from svn ffmpeg code cut, theora decoding does work.
Again I hope this is not only sufficient but you can consider it as

I've attached a simple source that, given the name of a video file, will print
the first 10 frames (as ppm).
To compile you'll need the following packages installed:
libavcodec-dev
Compile with:
g++ ./avcodec_sample.cpp -o av_sample -g -pthread -lavcodec -lavformat
-lswscale
example use:
for the theora sample I have on my laptop, I get this output:

Hi, the bug is confirmed by other users as well:

I already sent them a mail.
Now, what do I have to do to convince you of this issue in current Ubuntu

Post the source code (so you can compile and verify yourself) would be ok?
