Problem with a few DVB-T channels (1 Viewer)

[ltb76]

Hi,

I have a problem with some of my DVB-T channels, when switching to the channels I just get 1 frame and after that the picture freezes. So far I found the problem in 2 of the channels – the other channels works fine.

Cheers

Lasse

Hi!

Try another video decoder, such as PowerDVD or Nvidia!

Hi,

I've now been playing around with a few video decoders. The PowerDVD decoder provides no change.
The NVIDIA works with the channels that did not work before. But now MediaPortal frezes when going to the channels that worked before.

So I'm guessing the decoder is the problem - any suggestion to other decoders I can try with?

With the old setup I get these in the logs when I switch to one of the channels that does not work
[120]Aud/Ref : 367.365, Late Compensated = 1.233 ( 0.093 A/V buffers=01/09), Clk : 1.140000, State 2
[114]Vid/Ref : 367.532, Late I-frame(02), Compensated = 1.400 ( 0.229 A/V buffers=00/09), Clk : 1.171000, State 2
[114]Vid/Ref : 367.452, Late p-frame(00), Compensated = 1.320 ( 0.117 A/V buffers=00/08), Clk : 1.203000, State 2

Are they related?

Thanks for you help.

Are these encrypted channels? Do you think the problem might be related to encryption / CAM issues?
(do you find that Free To Air channels all work fine, and encrypted channels do not)

Are the channels that cause the problem all on the same transponder frequency? Is TV server using the correct frequency?

Are you using ffdshow for audio, if so go to the Audio config\codecs, select MP1\MP2 and change the associated codec, if newer version of ffdshow tryouts select libavcodec, older version mp3lib.

See if any better.

Might be also worthwhile disabling dxva for mpeg2 codec and see if any difference (raises cpu), thats just for testing

Hi,

No - none of the channels are encrypted.
How do I identify the transponder?

Belov I have written the details for 2 working and 2 non working channels:

Not Working:
Channel: 10000
Frequency: 690000
NetworkId: 0
TransportId: 91
ServiceId: 401
Bandwidth: 8 MHz
PmtPid: 33
Provider: Telenor

Channel: 10000
Frequency: 690000
NetworkId: 0
TransportId: 91
ServiceId: 407
Bandwidth: 8 MHz
PmtPid: 38
Provider: Telenor

Working:
Channel: 1
Frequency: 834000
NetworkId: 8400
TransportId: 1001
ServiceId: 101
Bandwidth: 8 MHz
PmtPid: 101

Frequency: 834000
NetworkId: 8400
TransportId: 1001

I have contacted the provider (COM-X) for the frequecies, but they do not wish to supply them.

I AM VERY HAPPY NOW

It works.

THANKS...

I'm happy for you that the problem is fixed. However, it seems strange that the some channels were affected by the codec problem, but others were not.
Anyway, I hope the problem is fixed permanently.

 

[Paranoid Delusion]

Should of explained more, some channels are transmitted dual mono, this can cause the issue that ltb76 saw, whole heartedly recommend anyone who use's ffdshow to upgrade to latest ffshow tryouts and for MP1\MP2 select libavcodec, or if using AC3filiter need to enable mpeg support.

Both have the same result

Thanks for this explanation.
