Modifications required for Essential Outdoor Camera 2

[sakza]

Figured it was worth a brief writeup - I was unable to get the essential outdoor camera 2 working with the standard setup in this repo, something about flv being incompatible with h265. Lots of digging later, and I ended up with a whole load of changes but ultimately a working setup. In camera.py, I changed the internal ffmpeg call in _start_stream():

self.stream = await asyncio.create_subprocess_exec( *['ffmpeg', '-err_detect', 'ignore_err', '-fflags', '+genpts+discardcorrupt+igndts', '-i', stream, '-c:v', 'libx264', '-preset', 'ultrafast', '-c:a', 'libmp3lame', '-ar', '44100', '-bsf', 'dump_extra', '-f', 'mpegts', 'pipe:'], stdin=subprocess.DEVNULL, stdout=self.proxy_writer, stderr=subprocess.PIPE if DEBUG else subprocess.DEVNULL )

This re enocdes with some error handling, which seemed to clear the issues with the original stream up. Seems like arlo uses some weird mpegts parameters.

Could you expand upon which file to make this change on? All of the cameras I use are Essentials Outdoor 2's, so I'd love to get my setup working! If you have a moment, it would be appreciated, otherwise thank you so much for providing this clue as to why our setups may not be working!

This change goes in the camera.py file, in the root directory of this repository - line 217. If you're using docker, you then have to rebuild the image, and tell docker-compose to use the image you've built, and not the original one from the internet.

docker build -t ffmpeg7-arlo-streamer:latest .

For example the start of my docker-compose.yml file is arlo-streamer: image: ffmpeg7-arlo-streamer:latest

From memory I was experimenting with a newer version of ffmpeg, hence the image name. Don't think it was important in the end

This is incredibly helpful, I was poking around in aarlo's camera.py and got confused. Thank you so much for explaining! I'm still somewhat new to these systems.
