No Video on Mythfrontend

Post by Buddierdl »

Hi all,

I need a little help with my Ubuntu 14.04 mythtv setup. I built it from source using the 0.27/fixes branch. I seem to have everything setup correctly using mythtv-setup, but I don't get any picture when I select "Watch Live TV." I am using a firewire card with an RNG 110 cable box, which seems to be working, because I can run

Code: Select all

test_mpeg2 | mplayer -cache 10000 -
and I get a picture. When I try to use mythfrontend, I just get 100% signal, partial lock (PL__) and no picture. Can you all help me troubleshoot? What kind of logs do you need?

Does the stream have PAT and PMT at the beginning? You can test with mythutil --pidcounter, if you only see the audio/video (and fill) PID then you are missing PAT/PMT. There is a potential fix #7205, which mentiong the PACE RNG-110.

This is what I get from that command:

Code: Select all

mythutil --pidcounter --infile test.mpg
Unknown argument for -v/--verbose:

2015-02-26 12:03:33.131876 C  Qt version: compile: 4.8.6, runtime: 4.8.6
2015-02-26 12:03:33.131886 N  Setting Log Level to LOG_INFO

PID 0x0f35 --        6096
PID 0x1fff --      506829
Does this indicate a missing PAT/PMT?

Are the patches mentioned in that bug report still usable in 0.27? Can you give me some guidance on how to fix this?
