[mythtv-users] Myth External Recorder - recordings fail

Sun Feb 23 00:37:32 UTC 2025

Hi all -

I'm running 34-fixes on Xubuntu 24.04.

The issue with the time-zone has been fixed by switching browsers with 
the new Web interface.

Recorders - old-school HDPVR 1212 box, which works fine most of the 
time, and HDHomeRun Prime (3 tuners, with CableCard), which the backend 
loses some of the time

(sometimes it shows up in Backend Status, sometimes not) and can't 
record from (recordings always fail, despite the fact that I can still 
scan channels from it's web interface).

I assume it's because CableCard is no longer supported.  So...

I bought an external black-box HDMI capture card, which I can use to 
watch TV or record from the STB using a script I wrote using cvlc.  
Using this manual script, I can record from it without problems.

Of course, I want to use it within Myth, so I followed the instructions 
in the wiki, using the exact syntax it provided (except to substitute 
the actual /dev/videoX and hwX,0 audio devices),

and created all the files as suggested, with the one exception being 
that I used the same channel list that I used with the HDPVR when I 
entered it in Setup.

I tested  the command line it uses, and it appears to be OK when run by 
itself.

I can set up the recording from the web interface, and it starts on 
time, changing the STB to the correct channel, but then fails; zero-byte 
recording.

Here's what's in the log.  Please advise as to where I'm going wrong 
here.  Looks like it can't create or find the file?  Why is the encoder 
"unknown"?

Any advice would be much appreciated!
