Network Recorder Experience

Ok some of the experimental debug message stuff was still there.

Martin

Could that be the cause of the crash?

[mvallevand]

Yes, as soon as the file transfer hits 2.2GB it would crash.

Ok, I'll do more testing a bit later today.

I'v completed one recording of about an hour without problems, but I noticed that there is no Timing.info in that recording. Will there never be when recording from the NR or is something gone wrong?

Ok good the recording is simple saved as streamed by NextPVR. If you need it for quality skipping, I wrote a standalone utility called writeTime that can generate Timing.Info in post processing. The mode that you are using only has limited practical use and that will probably be sufficient.

Yeah I'v already used WriteTime to generate timing.info to some recordings that would not skip (got exception "attempt to divide by zero") so I can put some lines in PostProcessing that check the recorder id (it's the 4th parameter to PostProcessing right?) and if it is a network recorder it runs writeTime.

Two NetworkRecorders seems to be working excellent now, thank you very much! Something that perhaps should be mentioned on the wiki, when streaming HD over a network one should be aware of the bandwith and make sure it is enough. With a gigabit network it is barely enough for two HD channels, and if there is other traffic the transfer from the remote npvr to the host can be held up, so to ensure that a recording is not cut off before all data is actually streamed I had to set the post padding to around 20 minutes.

[mvallevand]

Can you watch live tv? Even in 100Mb you should be able to record 4 or more HD broadcast quality streams. There might be a small problem if I don't flush to socket when NextPVR tells me to stop recording, but I can't imagine it would cache 20 min.

Live tv is a bit shaky, sometimes it works ok, but most of the time I get audio but no video, don't know why. I can watch in-progress recordings with no problems. I know, 100Mb should be enough in theory, but it turns out that the speed in real world is far less, maybe I have something in my network that causes a lot of retransmission.

[mvallevand]

If you need live tv try increasing the delay in seconds (1000ms) until it improves. Sounds like you need a little bit more buffering. Restart the recording service for the change to take effect.
