Security cameras keep it simple. They will not usually have bidirectionally
predictive frames as that generally takes a two pass encoder and adds
latency. Either way that is not the concern at the streaming level although
i think live555 will reorder frames if need be.
Remember that this is an RTS
As you surly must know, I'm a noob thrust unwillingly by circumstances into
this.
This is helpful. I don't need frames, just ten seconds of stream. But, doesn't

Strobe is an interesting word but I get what he means, It is a pull

Also, part of the problem here, I think, is that you seem to be confused by
what the class “H264VideoStreamFramer” does. This class takes as input an
unstructured H.264 byte stream, and parses it into discrete H.264 NAL units.
It *does not* combine multiple H.264 NAL units into a single ‘acces

I don’t know what you mean here. I don’t use the word “strobe” anywhere in the
code or documentation. Please stop makin
You need to create a filter and insert it into the chain.
I had this exact scenario and what I had was my own filter that handled the
incoming frames. All my frames were small POD classes with a bit of meta data
and a buffer holding the frame. I had a pool of these of different sizes and

Sorry. That wasn't clear. Yes, FramedSource derives from MediaSource, which
derives from Medium. RTSPClient derives from Medium.

Hello,
Sorry if this is a repeat, but I/we have constant email problems (political
issues), which I'm fairly sure I've now found a workaround for. What I'm saying
is that this may be a repeat. If it is, I apologize, I didn't get your
responses.
