Bitrate errore with tvheadend recordings #1

Closed BarnOwlDown closed 3 years ago

BarnOwlDown commented 3 years ago

This is what command tells me:

[matt@rpi3bp MattHDD]$ ./fbed.py 1 TV/A-Team-Iris.mkv

    bitrate = float(video_stream["bitrate"]) / 1000
KeyError: 'bitrate'

That's odd, it seems like it's not reading the bitrate when doing the ffprobe. Could you add a print(probe) on line 156 and paste the output here?

Interesting, the video stream doesn't have bit_rate field for this format for some reason. I've added some code in 667c7e0 to check for this case and use the bit_rate from the format field instead. I'm not sure if that includes the audio bitrate as well, but I think for this use case it's close enough. Let me know if that resolves the issue

It works! Thank you very much!
