Hi,
I have a specific scenario: in a restricted network
environment, I have discovered sometimes there is problem with
live reception of data via RTSP protocol. Reading at mailing
list and other locations got me to a point where I discovered
I could use HTTP tunneling to bypass proxies etc. I have
upcoming two streams:
1- RTSP live h264 stream
2- RTSP live AAC stream
When I apply HTTP tunneling method with h264 data, it works
without any problem. But, if I try it with AAC data, audio
never gets through.
Here is uncut console output when trying to fetch such AAC
streams via RTSP protocol, while the server is at a remote
location (some portions are changed to protect privacy):

As can be seen, it fails somewhere at " method PLAY failed:
500 SERVER ERROR". Searching online for this does not give me
much help, except that 500 SERVER ERROR is a general kind of
error (without any details).
This is the latest version of FFmpeg I downloaded from zeranoe
builds page today...
Has anyone experienced anything this sort before? Is there any
remedy?
Thanks in advance for any guidance...
Hi,
I have made little progress: if I specify "-initial_pause 1 " at
command line, then after waiting for about 40 seconds, I am able
to see new window pop up (the FFplay black window that shows white
stuff depending upon audio signal), but this window is totally
black, and even after waiting for some time, audio is never audible.
Do I need to signal initial_pause to 'off', somehow?
Here is updated command line with debug output (again some stuff
like server IP changed intentionally):

AAC works for me, but we use transport -rtsp_transport tcp flag. Maybe
your server is serving RTSP TCP over HTTP.
