You don’t need this. Generally speaking, a “H264VideoStreamDiscreteFramer” is
used only if you are about to transmit H.264 video, not if you’ve just received
it. (And a “H264VideoStreamFramer” would be wrong, because that’s used only to
parse a H.264 video byte stream, not discrete NAL units (which is what you
have).)
The problem is that - for H.264 - the NAL units that you feed into a
“MPEG2TransportStreamFromESSource” must each begin with a 4-byte ‘start code’
(0x00 0x00 0x00 0x01). Therefore, you need a new “FramedFilter” subclass -
that you would write - that prepends this ‘start code’ to each NAL unit, before
passing it to “MPEG2TransportStreamFromESSource”. I.e., you need:
scs.subsession->readSource() => your-filter-that-adds-a-start-code =>
MPEG2TransportStreamFromESSource
and then
sink->startPlaying()
as before.
ALTERNATIVELY (and MUCH simpler), you can modify
“testH264VideoToTransportStream.cpp” to change the “inputFileName” variable from
“in.ts”
to
“stdin”
and then just run
openRTSP -v rtsp://url | your-modified-testH264VideoToTransportStream
to get a Transport Stream file named “out.ts”. I.e., just pipe the stdout from
“openRTSP -v” to your modified “testH264VideoToTransportStream”.
