[FFmpeg-devel] x264 encoding over RTP and playing in VLC

[Dominik Tomczak]

Hello

I have just tried. I have still the same problem. Video looks like there:

I use Cygwin build of ffmpeg 0.5.1 with libx264. The same result I get with
MinGW build. I haven't checked yet the build of Linux version.
The cmd line is:
$  ffmpeg -i c:/Download/movie.avi -an -vcodec libx264 -vpre normal -b 1000k
-f rtp rtp://localhost:5000

generated sdp file is (session.sdp):
v=0
o=- 0 0 IN IP4 127.0.0.1
t=0 0
s=No Name
a=tool:libavformat 52.31.0
c=IN IP4 localhost
m=video 5000 RTP/AVP 96
b=AS:1000
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1

I start vlc by cmd line:
vlc session.sdp

Any ideas?
