[Libav-user] H.264 nal decode

[NITIN GOYAL]

Hey

do all ur raw payload u r sending to the decoding function are in NAL
format like 0001xRawpayload format??

I have done the same thing with the RTP packets. Removed RTP headers
inserted NAL start prefix headers i.e. 0001 before each NAL and then
entered the data to decoding functions.

And if the output is greater than zero, you will get the decoded output in
YUV format in the output buffer.
