thank you answer my question.
another question,i how to get each nal unit timestamp ?
thank you!
i want use live555 openrtsp get nal data from h264 encode device. i see
live555 testprog playcommon.cpp code.it <http://code.it/> use
h264videofilesink. my question:
1、i hope use playcommon get nal data rather than write file.so i must write our
myh264videosink? yes or no?
Yes, if you want to do something with the incoming NAL units - other than write
them to a file - then you will need to write your own "MediaSink" subclass to
do this (instead of using "H264VideoFileSink").
2、if use our myh264videosink get nal data,i how to get video config
info? i.e. video size and
video bit?
First, you get the 'sprop-parameter-sets' configuration string from the
stream's SDP description, by calling
subsession->fmtp_spropparametersets()
This returns an ASCII string, that you can parse with the
"parseSPropParameterSets()" function, to get a set of (binary) NAL units
(usually, SPS and PPS). (Note, for example, the implementation of
"H264VideoFileSink", which calls "parseSPropParameterSets()".)
