Cannot watch recordings on phone or mac

Question

Cannot watch recordings on phone or mac

VC-Semih opened this issue a year ago · 11 comments

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

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

Answer 9 · 2023-10-19T21:27:24.000Z

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.

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