<div>Also, I get NAL Units with fragments. </div></div></blockquote><div><br></div>What specifically do you mean by "fragments" here? Do you mean slices? I.e., are you talking about NAL units that each represent just one 'slice' of a frame (picture)? If so, then yes, we support this. You can treat these NAL units just like any other; deliver them (one at a time) to the downstream "H264VideoStreamDiscreteFramer".</div><div><br></div><div>Or are you instead referring to multiple chunks of data (that are *not* NAL units themselves) that, if combined together, form a single (large) NAL unit? If so, then you *must not* deliver these chunks of data separately. Instead, you *must* combine these chunks into a single NAL unit, and deliver this completely (without the 'start code', of course) to the downstream "H264VideoStreamDiscreteFramer").</div><div><br></div><div>Another thing to be aware of is that if a NAL unit can be very large, you may need to change the value of "OutPacketBuffer::maxSize" (in "testH264VideoStreamer.cpp" from 100000 (bytes) to something larger.</div><div><br></div><div>Far better, though, is to (if possible) reconfigure your encoder to break up such large NAL units into multiple 'slice' NAL units.</div><br><br><div apple-content-edited="true">
