[Libav-user] [h264] RTP: missed X packets: corrupted images

Hi all

I'm using the latest version of libav (2.0.2). I'm writing a simple code
test (attached with .pro file) for camera streaming.

My libav is compiled by me in debian squeeze amd64 (./configure
--prefix=/opt/ffmpeg/ --enable-shared && make && make install)

If my simple code test is compiled against ffmpeg 0.8.15, I have no
problem.

If my simple code test is compiled againts ffmpeg 2.0.2 I have always the
same problem:

[h264 @ 0xbe40a0] RTP: missed 12 packets


this message is repetead hundreds of times with other messages like this:


[h264 @ 0x1d102c0] mb_type 27 in P slice too large at 23 23

[h264 @ 0x1d102c0] error while decoding MB 23 23

[h264 @ 0x1d102c0] Cannot use next picture in error concealment

[h264 @ 0x1d102c0] concealing 2986 DC, 2986 AC, 2986 MV errors in P frame

and  sws_scale give me a corrupted image (attached). I attach the ouput of
my program with AV_LOG_DEBUG

Anyone can help me?

Best Regards

Rafael L.
