[Live-devel] RTSP Interleaved Streams

[Piers Hawksley]

Thanks Bob,
Thanks for the pointers on how to test with VLC. Very useful info on GET_PARAMETER. I'll post my findings early next week.
Cheers,
Piers

Piers,

I have not yet found a way to get VLC to request RTSP interleaved data, so
I am limited in how to test this at present.

VLC does support RTSP-over-TCP. This option may be configured from the GUI
or from VLC config file.

GUI:

Tools > Preferences > Input/Codecs > Demuxers > RTP/RTSP > Use RTP over
RTSP (TCP)

Config File (Linux):

~/.config/VLC/vlcrc

# Use RTP over RTSP (TCP) (boolean)
rtsp-tcp=1

On windows you might have to search around for this file.

Frame 177 has a block of 112 bytes on the end which does not appear to be
valid data.

I believe this might be related to VLC sending GET_PARAMETER requests for
keep-alive. live555 appears to have data in the body of the response
(LIVEMEDIA_LIBRARY_VERSION_STRING). If you run VLC from cli like this:

 cvlc -vvv rtsp://some-ip:port/somestream --sout=file/mp4:file.mp4

Do you see this or something similar?

Have received 112 total bytes of a GET_PARAMETER RTSP response; awaiting 2
bytes more.

I'm not sure if this is significant or not? Thought it might be helpful to
pass on my observation.

I wish VLC would get up to date with the live555 code base!

Bob
