[Libav-user] How to use API ffmpeg to capture a vnc stream and create the output video file?

[Daniele Colasante]

Hello I am Daniele Colasante,

 

I would like to understand how to use API ffmpeg to capture a vnc stream and
create the output video file.


I tried from vnc2mpg.c (from
http://libvncserver.sourceforge.net/doc/html/vnc2mpg_8c-example.html ) and
muxing.c (from
http://www.ffmpeg.org/doxygen/trunk/doc_2examples_2muxing_8c-example.html )
but I got poor results.

Has anyone ever done this? Any suggestion is welcome. Thanks to all for your
attention and sorry for my English.

 

Attached my code, video.c, when I run: ./video -o video.avi -t 30
ip_address:port vncpassword  the results are:

Output #0, avi, to 'video.avi':

Stream #0:0: Video: mpeg4, yuv420p, 1680x1050, q=2-31, 400 kb/s, 90k tbn, 25
tbc

[avi @ 0x1ec4060] Application provided invalid, non monotonically increasing
dts to muxer in stream 33754816: 269628272584 >= 0

Error while writing video frame: Invalid argument
