Have you checked your client is able to play it ? it is possible that the channel use 10bit instead of the common 8bit !

Recording this channels the client plays fine.

Ok, somehow framerate not computed. I don't know how it computed in hevc, but after this workaround my hevc 1080 channels started working.

.
if (width && height && d)
parser_set_stream_vparam(st, width, height, d);

sorry...

Could you save the descrambled but unmodified TS stream (pass-thru profile) ? Cca 20 seconds and attach it to this bug.

From Examples there is a problem with operator transcoder attributes

/first stream i see with vertical crop for interlace,
1920x540 normaly is 1450x1080 also missing aspect ratio attribute/

it's known issue and stupid provider
