  • Decoding H.264 individual nal units

    24 September 2018, by madprogrammer2015

    I am currently sending individual NAL units across a network. These NAL units are generated by x264. Now is it possible to feed these NAL units individually into avcodec_decode_video2?

    Or do I have to concatenate the nal units until they represent the same frame? If thats the case then how is that done?

    I have also read that I might be able to receive the SPS and PPS packets. Then wait for at least one packet, and attempt to decode. Is this correct?

    Any advice that can be offered would be greatly appreciated
