Hi,
I have a Leadtek capture card that provides DirectShow output. I managed to
record video in multiple resolutions using the command line ffmpeg tool by
providing the -s widthXheight option. Unfortunately I could not replicate
the results from code: it always captures with the default 320x200

How difficult would it be to compile the examples in the doc/examples

Those are C programs, so just use a C compiler for them. Thatapos;s all I
meant.
Okay, I understand. Yes they are just C programs, so I can compile with
the C compiler. But my C++ programs
I want to create several pthreads in a C++ program (assuming you can call
libav routines from a C++ program) that each call libav subroutines.
Are the libav subroutines thread-safe? Specifically,
can several pthreads open the same AVI file and decode different video
frames concurrently?

Hi,
I am trying to use this library for a commercial Android application, but I
would like to know if the compression of a video and cropping of the video

Well, yes, you can call C from a C++ app. You need to mark the headers as C

I am using FFMpeg to receive RTMP streams. It decodes and plays the RTMP
stream correctly but I have problems playing the video for long periods of
time.
It seems that
av_read_frame(format_context, packet);
returns an AVERROR_EOF after playing for a period in time say 7 or 8 mins,
this occurs
