Timestamp oddness, frames out of order? about docker-wyze-bridge HOT 13 CLOSED

I've noticed that sometimes.
Wonder if we might be able to do something with FFMpeg?

from docker-wyze-bridge.

I've just tried adding:

'-fflags', 'nobuffer',

to FFMPEG params and it's been better for me. But that might just happen to be a one off . I'll keep on trying with that.

Edit: nope no dice back to same behavior after a while.

I think recordings from Frigate are fine, so I tried using the input and output parameters from the Frigate config, but no luck, still getting odd frame order when viewing live.

Have you tried -err_detect ignore_err or some other fflags like +flush_packets +genpts or +discardcorrupt

I wonder if moving to something like gstreamer or an alternative would help..? Open to suggestions!

from docker-wyze-bridge.

Yep, I've tried those, here's ones I've tried (both commented out ones too, this just my file as is).

-hide_banner',
# '-stats' if 'DEBUG_FFMPEG' in os.environ else '-nostats', #'-nostats',
'-avoid_negative_ts', 'make_zero', '-fflags', '+genpts+discardcorrupt',
'-use_wallclock_as_timestamps', '1',
#'-err_detect', 'ignore_err' '-loglevel','info', ## if 'DEBUG_FFMPEG' in os.environ else 'fatal',
'-f', sess.camera.camera_info['videoParm']['type'].lower(),
'-framerate', sess.camera.camera_info['videoParm']['fps'], '-i', '-', # '-b:v', str(bitrate)+'k', #'-reset_timestamps' , '1', '-strftime', '1',
'-vcodec', 'copy',
'-f','rtsp',

Does enabling PYTHONUNBUFFERED=1 in your docker-compose help?
Also, could you give the arm version a try? For some reason it seems to be more stable.

from docker-wyze-bridge.

I'll try the PYTHONUNBUFFERED=1 - on using the arm version, I'm on ubuntu on an intel i7 - do you still want me to try it?

Edit: PythonBuffered didn't seem to help, still seeing the odd frame order artefacts if I let it run for a minute or so.

Are the frames out of order on all streams or just hls?

from docker-wyze-bridge.

I've only looked at rtsp.

Does adjusting the popen bufsize help?

from docker-wyze-bridge.

No joy on that either - fiddled around with settings but bufsize=1024*100 seemed to work in, the sense of getting a steady stream, but still jumbled timestamp.

Is this still an issue with v0.5.0?

from docker-wyze-bridge.

Looks good now - jumping back on board after returning to wyze RTSP, now looks stable and no timestamp issues, thanks for your efforts @mrlt8 .
