[Libav-user] Decoding a H.264 stream from TCP

[Jeremy Graham]

Hello, everyone:

I am working with the Parrot AR.Drone 2.0.  I don't know if anyone is 
familiar with that device, but to make a long story short, it transmits 
video data from an on-board camera via TCP and the video is encoded with 
H.264.  I am trying to make a program that continuously receives the TCP 
packets from the drone and decodes them in order to get the images sent 
from the camera.

Could anyone steer me in the possibly correct direction toward 
accomplishing this goal?  I tried to do it based off of code like what 
can be found here 
http://libav.org/doxygen/master/libavcodec_2api-example_8c-example.html 
or here http://dranger.com/ffmpeg/tutorial01.html.  However, I am 
getting nowhere.  I guess getting frame data from network packets is not 
like getting it from an actual video file.

I am a complete novice when it comes to video, codecs, and streaming 
video over a network.  If someone could help me figure out where to even 
begin I would be so appreciative.

Thanks!
