"Probe failed for live stream"

Playground Custom Channels
#1

I'm currently trying to use mediaflow-proxy to handle some of the more complicated parts of iptv. This was working for awhile, then suddenly it stopped working a few weeks ago. The strange thing is the same playlist works just fine in mpv.

When I try to play any of the streams in Channels, I see this in the logs:

I've tried tweaking everything I can think of, but as far as I can tell mediaflow is successfully responding to the requests and the logs for it look the same as the logs when I stream using mpv

I know this is unlikely to be enough information to debug, but has anyone seen anything like this, and are there any 'hidden settings' or the like in Channels that I can play with?

Examining the stream might tell you if something is not aligned with Channels (i.e., wrong stream type, has DRM, etc...).

#3

I'll get SLM installed I guess, but here are the stream details from mpv (which plays it fine):

● Video  --vid=1               (h264 1280x720 59.9401 fps)
● Audio  --aid=1  --alang=eng  (aac 2ch 48000 Hz)

There were a few 404s on the playlist in SLM, but that was expected. the rest of the channels "responded 'HLS'"

Here's a screenshot of the channel i've been testing with
