mp4 recording won't play

[VCR58]

That is expected as I posted earlier you would need to transcode your mp4 files and not just remux them.  You could also use your HDHR Extend and turn on transcoding by default and the files would already be h264.

Ok, I missed that. Still learning about remuxing and transcoding.

After transcoding to h264 I was able to direct play the .mp4 recording in the NextPVR Android app and also could play it in the NextPVR web client. Jellyfin said it was direct playing both video (h264) and audio (AC3) when it played the .mp4.

Transcoding the .ts file with ffmpeg from the Linux terminal took 1 hr 59 sec for just one recording so I think using the HDHR Extend for transcoding might be better.

When you say "turn on transcoding by default" are you referring to creating the Extra HDHR device with the Python script and use that for recordings?
