RTSP failes after "SETUP" (406 Not Acceptable)

Posted: Thu Aug 30, 2018 6:30 pm
by arhi
Hi,
Using some noname PRC made IP camera that supports RTSP and ONVIF and ...
turned off credentials check to make things simpler (same issue with credentials on)

VLC/PotPlayer.. view the rtsp stream without problem
fflplay too

so this works: ffplay rtsp://192.168.89.60/11
also using this url in vlc/potplayer works: rtsp://192.168.89.60/11

rtsp running on default 554, this url works too as expected rtsp://192.168.89.60:554/11

debug log show zero useful info even with debug level 9:

^C
15 packets captured
16 packets received by filter
so after the SETUP is sent camera reply with 406 not acceptable and zmc dies with "no rtsp sources" in the log

on the other hand, ffplay tcpdump shows it works nicely

here I see ffplay does
DESCRIBE rtsp://192.168.89.60:554/11
SETUP rtsp://192.168.89.60:554/11/trackID=0
SETUP rtsp://192.168.89.60:554/11/trackID=1

and then
PLAY rtsp://192.168.89.60:554/11/

so the /trackID=0 and /trackID=1 is added to the url ...

if I try to add this to the url directly in zoneminder path it fails bit differently:

Don't assume the resolution is correct. Use VLC (Tools, Media Information, Codec) to check camera Display Resolution.

Ah... and use ffmpeg

the resolution is ok (VLC confirms it)

what's the point of zm understanding RTSP protocol if I need to use ffmpeg to recode it? it does work with ffmpeg but it's using lot more cpu then using direct RTSP

What is the point of us duplicating code that exists in ffmpeg?

I might be wrong in understand how it works. If I understand correctly FFPMPEG transcode the date into something that is then used by the zmc/zma .. while RTSP protocol is read directly by zmc/zma... I believe that 'cause when ffpmpeg is used cpu load is lot higher then when rtsp protocol is used (as with some other cameras rtsp works)... hence I assume using rtsp directly is better option (less resource intensive) ...

as for "duplication", why rtsp protocol exist at all, why local, remote, tcp, web.... ? why isn't there only ffmpeg source available? there must be reason why all these other sources are there :D ...

I believe this "bug" requires just a small tweak to rtsp protocol, I'll fetch the sources and see where/how it's implemented, but the "not recommended to self compile" thing made me thing it's better to post here then to spend time going trough code and tweak the source myself .. seems I was wrong so "to the code" it is :D
