troubles with Hero 7 Black streaming

[tylerstraub]

When running the .stream() command on the Hero 7 Black we are receiving a lot of problematic output.

Any ideas out there? Has anyone been successful firing up a UDP stream on the Hero7 Black?

Thanks!

gopro.stream("udp://127.0.0.1:10000")

This is running on the raspberry pi right? I'd suggest uninstalling FFmpeg and compiling FFmpeg from source (https://git.ffmpeg.org/ffmpeg.git)

[tylerstraub]

It is, but the distribution is not a typical one (OpenMPTCPRouter, a derivative of OpenWRT). Perhaps the OPKG build of ffmpeg is too out of date. Thank you for pointing me in this direction, I will attempt to build FFMPEG from source and report back on my findings.

[tylerstraub]

It was indeed FFMPEG.

We were able to test the UDP feed but the overall stability and quality was not great.. the UDP stream coming from the GoPro will not meet my requirements unfortunately.

Going to have to use an external encoder after all. Thank you for pointing us in the right direction!
