Describe the bug
I'm trying to run v4l2rtspserver to use my RPi Zero W as a small security camera. Got the latest raspbian, updated all packages to latest, then installed v4l2rtspserver from the git repo. Was initially having some trouble getting it started, then found the LD_PRELOAD tip on #283 for the new libcamera v4l2-compat support.

I started it up using LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/v4l2-compat.so v4l2rtspserver /dev/video0 as root (just to get initial settings right, then run as daemon as regular user).

Starts up with this output

I then try and connect from VLC on my desktop to rtsp://192.168.10.70:8554/unicast, and get an error in VLC

Your input can't be opened:
VLC is unable to open the MRL 'rtsp://192.168.10.70:8554/unicast'. Check the log for details.

On the Pi, I get this output

handleCmd_SETUP:SETUP rtsp://192.168.10.70:8554/unicast RTSP/1.0
CSeq: 0
Transport: RTP/AVP;unicast;client_port=9284-9285

Can't see anything specific in the output, any ideas? Any tips on directions I could go in to try and figure out the issue?

Hi,

Last time I tried VLC doesnot support NV12 format. You could use ffplay that support it.

Best Regards,
Michel.

Hm, so how do I change the format? I've tried using the -f option, but that doesn't seem to work. Would using the v4l2loopback and having the loopback provide the correct h264/whatever format work, assuming I use the -f with no options to tell v4l2rtspserver to use whatever the current v4l2 format is set to?

Hi,

-f options has 2 usage without argument (it keep actual format) with argument (for instance -fH264, it set the format, and if format is not supported by device, it fails)

Best Regards,
Michel.

I have the same issue as @Drizzt321 , I used libcamerify instead of the LD_PRELOAD method, but I can't get the stream to be played neither by VLC (which is normal according to your previous answer) nor by ffplay.

Hi,

Did you try to add '-strict -2' ? as proposed in :
[bitpacked @ 0x7ff238006480] The decoder 'bitpacked' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

Best Regards,

Hi Michel,

I struggled quite a bit and finally got a video stream, it seems that there are two different issues, I opened the following issue : #299

When things are working, I can get a video feed on ffplay, but it seems it is not picked properly:

image

My guess is that the format provided by the camera is not compatible ?

Update: going back to the V2 camera has the same behavior, I'm not quite sure what is going wrong here.
