(Solved) Can not watch Live TV

Post by ryanad1 » Mon Sep 17, 2018 8:01 pm

Linux newbie here. I have Xubuntu 18.04 with MythTV 0.29 installed. I'm able to record and play back, but I cant watch live tv. When trying to watch live tv I get an "Error opening Jump program file buffer".

Here is my Frontend log:
FrontendLog.txt
(22.13 KiB) Downloaded 6 times
And Backend log:
BackendLog.txt
(6.23 KiB) Downloaded 9 times
From what I've been able tell, it looks like the backend is creating two files, but only recording to one. The frontend appears to be trying to open the file that doesn't get recorded to.

Being a relative newbie to both linux and mythtv, im at a loss as to how to fix this. Any ideas would be greatly appreciated!

Try increasing the tuning timeout values in the tuner setup. I believe the default is normally 3000, try doubling that.

Tried increasing the timeout from 3000ms to 6000ms.. Still have the same symptoms.
I don't know if it makes a difference, but I'm using a Hauppauge hvr-2250 tuner card.

From mythtv frontend log
Sep 17 14:03:58 DVR mythfrontend.real: mythfrontend[1355]: E CoreContext fileringbuffer.cpp:309 (OpenFile) FileRingBuf(/mnt/Video-Storage/Live TV/1051_20180917190358.ts): OpenFile(): File too small (0B).

You have a space character in Live TV directory name, suggest you rename the directory to Live_TV i.e. use underscore instead of space, remembering to change the Live TV Storage Group using mythtv-setup to /mnt/Video-Storage/Live_TV

I presume you have set the appropriate ownership and permissions on this directory for mythtv

Taking MikeB2013's advice, I changed the Live TV directory to Live_TV. Solved the problem!

Thank You!
