Hi, I'm developing a C++ application to measure the PSNR (and other stats) of multiple video files. To access video streams I decided to rely on libavcodec, so I installed libavcodec-dev package to get the header files (I want to use it as a shared library). Currently everything works but Theora video streams. When I open such streams I get corrupted frames (wrong colours and unrecognizable images), while when other streams are opened (h264/xvid/wmv/...) everything is fine. Apart that the header file in that package is old (it doesn't export avcodec_decode_video2 function), I can't find the function (avcodec_decode_video2) even with dlsym once the library has been loaded (other functions like avcodec_decode_video, deprecated, are found). I guess that the default libavcodec.so.52 and header files that come with that package are old/deprecated, am I correct?
When instead I liked static libraries from the SVN FFmpeg source, the function avcodec_decode_video2 was found and Theora video streams are now properly read and decoded (with both avcodec_decode_video and avcodec_decode_video2). I would not like to use static libraries in my project, but I'd rather have an updated libavcodec.so. Can you please look into that? Regards, Ema. Ps.
