Hello All,
I'am new to ffmpeg devel , and i have a question regarding
h263 (ffmpeg) and rtp (not using ffmpeg rtp), with relation to a 3gp file.
I have a 3GP file, which i need to transmit over the network over RTP. I
have an RTP stack, and RFC 2190 packetizer.
Now I'am able to open the file, codec, create the Format context etc. as
given in this excellent example source code.
http://www.dranger.com/ffmpeg/.
My question is as i read the video stream, which is h263 encoded from the
3GP file using av_read_frame(), i get the data in the AVPacket struct,
now can anyone tell me what i'am supposed to do from here, am i supposed to
send the AVPacketData directly to the Packetizer
or should i do something else before it is packetized (to collect a whole
frame etc. )and send via RTP.
Currently i'am able to transmit the H263 video, i do a avcodec_decode_video,
when i read a complete frame,
then i convert the frame into yuv format, and provide it to the packetizer,
it works, but i feel the decode is not required,
to make my question short, Is there a way to send the encoded h263
bitstream from the 3GP file , without having to decode the video into a
AVframe, and then convert it to YUV ?
Please let me know.
Thank you.
Cheers,
Simith Nambiar
