Hi, thanks for explanation, and because the libavfilter ABI is now declared unstable based on the notes from Libav website[1], it is reasonable to stick to Libav 0.7 series until Libav becomes stable. And I should clarify that Ubuntu 12.04 uses Libav, not FFmpeg, sorry for that confusion.
Ah ok. It seems that the FFMPEG and libAV APIs are still somewhat compatible. Also, we're using some very old features, which is where the problem lies.
You're probably in luck though: I have some newer ffmpeg code which I need on a current project, which I've been meaning to integrate into libCVD for a month or two now. I'll probably do it in the next week or so.
By the way, libcvd will generate three share libraries "libcvd.so", "libcvd.so.0" and "libcvd.so.0.8", but invoked "sudo make install", only two share libraries "libcvd.so" and "libcvd.so.0.8" were copied, the share library "libcvd.so.0" was not installed into /usr/local/lib.
I've not encountered that problem, but I'll take a look. Can you paste the output of make install? -Ed
Has anyone encounter this problem? 2012/7/11 E. Rosten <address@hidden>:Hi I'm afraid that we don't yet support the 8.x series of FFMPEG, since they've changed the interface (again), but unlike other previous changes, it is not obvious how to upgrade ot the new API. For now, the best workaround is to install an older version somewhere, and compile against that. I think anything in the 0.7 series should be OK. I'm on 0.7.11 and it works fine. A 0.8.x compatible version will be made at some point, but when 0.8 came out most of the documantation was rather poor.

It seems that the const MAX_STREAMS has been removed from avformat.h?
