Hi Guys
Does LibAv current support RTSP authentication (digest/basic)?
Yes it does, see
http://git.libav.org/?p=libav.git;a=blob;f=libavformat/rtsp.c;h=d0e9bbf6af6534b0e2f8c841b6cb763f0a41f4dd;hb=HEAD#l1370
I am connecting to a url of the form
"rtsp://user:[email protected]/rtspl?h264&channel=1" which works
fine
in VLC but not through LibAv/FFMpeg. I just get the line "[rtsp @
003EB7E0] method OPTIONS failed: 401 Unauthorized" when I try this
through the command line.
Should work there as well, could you please provide an url we could
test?

Hi Luca
I have traced the issue and it looks like LibAv is not creating the auth
response correctly. The details are as follows for the first call
(OPTIONS)
user="live"
password="sureview"
realm="Use 'live' as User Name"
nonce="1f63550066114283365d7d9a346e5dff"
uri="rtsp://10.128.3.7:554/rtsp_tunnel?h26x=4&line=1&inst=1" (note that
this is behind a VPN so you wont be able to see it)
LibAv is generating the response as "ea214b7c7f218d0053ad9467003e14aa"
I have calculated the response should be
"5d7ee8885c6ae3c64055bdb9e21f88ca" using the information on
http://en.wikipedia.org/wiki/Digest_access_authentication. I have also
tried this against the OPTIONS request and it succeeds!
Does this help at all? If you need more information I will post whatever
you need.
I'll have a look and ask Martin to check as well. He is using the
feature so is strange to have it wrong.
Could you please provide a whole wireshark dump so we can see the
whole exchange between the two parties?

Hi Luca
Attached are a successful and unsuccessful RTSP connections. The
successful one is from VLC which seems to work perfectly.
To make them smaller.
