Hello,
I upgraded to v0.7.2 and now avformat_open_input always returns "No
such
file or directory" (-2). I tried it with files and http-mjpg
streams but
it makes no difference.
Call looks like this:
AVFormatContext* context = NULL;
avformat_open_input(&context, "some file or stream", NULL, NULL);
Please help :)
what happens if you strace your application? which file does it try to
read?

Sorry my fault. I linked the program against libav and opencv which
linked statically against an older version of ffmpeg ...
You might need

Thanks, but this patch doesn't solve all errors. E.g.:
modules/highgui/src/cap_ffmpeg_impl.hpp:548: error: ‘CODEC_TYPE_VIDEO’
was not declared in this scope
Anyway I'm content with opencv compiled without ffmpeg...
