You are too vague.
Why does the muxer care about the encoding? Should he only know about the
packets?
Most formats store that information somewhere in the file headers.
Without a demuxer how to you get stream data into the muxer?
From the encoder, as I already hinted in my first mail and explained in the
second. Did you even read it?

Regards,
I have fixed the issues and it appears to work without deprecated calls.

Somebody should add a bit in headers as the codecpar is in
libavformat/avformat.h
but this usage is in libavcodec/avcodec.h
This is good stuff, just kind of in the wrong place....IMHO

the "_to_" vs "_from_" was just escaping my vision... course I am an old fart.
I swear I looked at that section of the header a dozen times and never saw it.
Thankfully I was looking at avcodec_copy_context
demux -> avcodec_parameters_to_context
mux -> avcodec_parameters_from_context
just a suggest as a person looking in from the outside..
Thanks

Nicolas,
I really DO appreciate the time you spent to respond. Which is why I asked the
vague question about the constructs in play here.
After I read your first email, I updated the code, so it was useful.
I did NOT see your second email, only the first email that basically told me
what I already knew.
Was setting too much crap and not connecting the encoder and stream the correct
way.
FYI: This is a very difficult ABI to learn so "hints" are worthless when
someone is stuck.
Maybe if I had seen your second email...
It would have been helpful if you had said:
"Hey dummy, you need avcodec_parameters_from_context for muxing"
Finally, top-posting, you are just being condescending at that point - "look it
up". Frankly, to me, it came off as rude.
I actually read the rules and was bottom posting at first, but several people are top posting all the time so I tend to go with the flow of
traffic. If it makes you fell better I will always bottom post in response to you, because that is the kind of person I am.
Doing the happy dance !@@!
Take care,
Charles
