Ubuntu + HDHomerunPrime + Prime Encoder

[matt91]

Just installed a HDHomerunPrime (w/ cable card) on my setup, which required me to utilize the great prime_encoder script to get my installation to be able to interface with the unit.

I only got this setup last night, so I haven't done extensive testing, but I have noticed that something fails at about 15minutes in to a recording.

Additionally, i'm seeing hundreds (if not thousands) of these lines in the log:

This all being said, things seems to be working OK. I can view these files and they seem OK (although Comskip didn't run on them, but that may be some other issue.)

Anyway, just wanted to see if anyone had any thoughts on this.

Thanks,
Matt

Matt,
I haven't seen those Java errors on my setup - is that from sagetv_0.txt?

Does the Sage system page report that it thinks the video device became unavailable when recording?

Just to verify, the prime_encoder.log output is from recordings, not the preview channel setup screens or live TV?

What version of ffmpeg are you using? I had problems with some older versions but it was after 2+ hours of continuous recording of a single sports event. Compiling a version of the latest made those problems go away for me.

John -

Yes, those errors were from the sagetv_0.txt log. After stopping/starting Sage a half-dozen times, they seem to have disappeared. I'm not sure what it was, but it doesn't seem to be in the log today, so i'll call that "fixed!"

As for the stopping/starting of the video files, sage does through an error when this happens. I did decide to compile a newer version of ffmpeg, and it seems OK today (I've recorded a few shows, and none of them get split into a XXX-0.mpg and XXX-1.mpg file, as was happening.)

So, fingers crossed, but things seem OK now.

thanks for the feedback.

Matt
