Cannot watch recordings on phone or mac

[VC-Semih]

Using https://github.com/kerberos-io/camera-to-rtsp with a Logitech C270 I can watch my recordings only on Windows (and probably Linux did not test) but not on Mac or Android phone I can only watch them if I download vlc and open the file with it. Does someone have a clue about this ? Thanks !

PS: demo.kerberos.io works on mac so it could be due to camera-to-rtsp ?

Here is the command line in the yml config: ffmpeg -f v4l2 -i /dev/video0 -preset ultrafast -c:v libx264 -x264-params keyint=60:scenecut=0 -f rtsp rtsp://myip$RTSP_PORT/$RTSP_PATH

I'm guessing libx264 is causing the issue

Hey @VC-Semih, interesting, what happens when you drag and drop these recordings into your browser. Do they also play then?

• First download locally to your host system
• Open your browser, and drag you recording into the browser

Hello ! Thanks for your reply.

I only have a spinner that turns indefinitely, even when I download the file only VLC can play it, the MacOs quick time player says that the file is not compatible

Just tested downloading the file on windows, the "Movies & TV" App cannot read it too, I only have a black screen with the player stuck (video timecode not changing) but the browser can read it (with drag and drop as you suggested) I don't know if the file will be processed by github but here is a video upload of a recording https://github.com/kerberos-io/agent/assets/55637588/e1ff67ad-61fe-481c-b054-f9c35a23d901

Hmm I can play it from the browser

Hmm that's strange, here is a screen capture on a Google pixel 6 with android 14:

For debugging purpose here is ffprobe result on a recording

Little update, I did find a way to make recordings readable by Android and MacOs using ffmpeg -f v4l2 -i /dev/video0 -preset ultrafast -c:v libx264 -profile:v high10 -vf format=yuv420p -f rtsp rtsp:192... but the live video and the movement detection is no longer working

[VC-Semih]

After a lot of tinkering I have an ffmpeg command that works on Mac Android & Windows and works with Kerberos live stream and movement detection

ffmpeg -f v4l2 -i /dev/video0 -preset ultrafast -c:v libx264 -x264-params keyint=60:scenecut=0 -vf format=yuv420p -f rtsp rtsp://192...

@VC-Semih what environment variable does that ffmpeg command map to? I am having difficulties finding where this goes in the yml.

[VC-Semih]

@yllekz using camera-to-rtsp repo, replace the "runOnInit: ffmpeg..." with the command above if you have similar problems to mine
