Paging Martin --- IP camera as a extras channel

[mvallevand]

If you want this to work, you are going to probably have to remux it and you still will have errors on the input it is the output you want clean

-fflags +genpts -r 30 -i rtsp.... -vcodec h264 -acodec aac

Can you help me out, ffmpg is not my fortee.  I tried to incorporate what you said, but obviously I got it all dorked up cuz it don't work

Code:

<args>-re -fflags +genpts -r 30 -i -rtsp_transport tcp -i "rtsp://xxx:xxx@192.168.1.182:554/11" -vcodec h264 -acodec aac -f mpegts -</args>

[mvallevand]

Try it from the command line first, but it looks like there is an extra -i now before -rtsp_transport

Martin, I've  got a steam with this, but I'm sure it's got some issues in the arguments.  Do you see anything I can do to clean it up?

Code:

<args>-re -v panic -f lavfi -i anullsrc=r=48000  -rtsp_transport tcp -i "rtsp://xxx:xxx@192.168.1.182:554/11" -vcodec h264 -acodec aac -f mpegts -</args>

[mvallevand]

You don't need this anymore -f lavfi -i anullsrc=r=48000 since your camera has audio and you took out the genpts but if it works with the raw transcode that is ok.

Just to close the loop; I've got it work with this arg:

Code:

<args>-re -v panic -f lavfi -i anullsrc=r=48000:cl=mono -rtsp_transport tcp -i "rtsp://xxx:xxx@192.168.1.182:554/11" -vcodec h264 -acodec aac -f mpegts -</args>

For some reason when I took out the "lavfi"  and "anullscr" it wouldn't run.  I put it back in and changed it to "lavfi -i anullsrc=r=48000:cl=mono" and it works.   Not sure if "anullsrc=r=48000:cl=mono" is an improvement or not but it seems to allow the stream to start a few seconds sooner or its just my imagination but either way it's working,

Thanks!

Do you get sound from your camera in normal use?

Martin

[snagglewest]

This camera doesn't have sound and the couple that do I've shut off on the camera as they're all exterior and up fairly high.

Martin,

Would you please revisit this with me?  If you recall I had made an extras that worked, at least on my main vero4k box and via a web UI.  For some reason the raspberry pi boxes never did like it but at the time it wasn't a big deal.  Well fast forward to now...  The vero died and I replaced it with a Pi4 using libreelec kodi.  

When I select the extras channel (in this case #1936 - Front_Yard) it will only display a black screen.  I can see in the livetv folder on NextPvr that the live TV file is being created and growing so that indicates to me the problem is most likely the Pi.    I'm guessing the problem is the stream format.  The normal tv channel is mpeg2 where the extras one is h264.

Attached are NextPVR & the Kodi log from when I tried to play the channel along with screenshots of the 2 channels.

I'm way outside of my knowledge area so I'm asking for you help me get a extras argument that will play.

Thanks - Snag

Camera can be accessed from VLC with"

Code:

rtsp://[username]:[password]@192.168.1.182:554/11

Extras code:

Code:

<args>-re -v panic -f lavfi -i anullsrc=r=48000:cl=mono -rtsp_transport tcp -i "rtsp://xxx:xxx@192.168.1.182:554/11" -vcodec h264 -acodec aac -f mpegts -</args>

[mvallevand]

I don't have a clue what you mean with a normal channel I assume that just is broadcast.

First did you you verify you have a working extra? You can play with the input

Code:

ffmpeg -re -v panic -f lavfi -i anullsrc=r=48000:cl=mono -rtsp_transport tcp -i "rtsp://admin:admin1@192.168.1.182:554/11" -vcodec h264 -acodec aac -f mpegts - | ffplay -i pipe:

I am not an RPi4 fan so not too interested in helping further on the playback. It is a better server than client. In theory h264/aac shouldn't be an issue.
