2 Channels dark but with sound

Elmo Putney · 2012-04-04, 01:27 PM

Martin,
I've got 2 sat channels that refuse to show video on the NMT, this happened after I stuck a new card in my box and re-scanned, other channels on the same transponder are ok.

I think this may have happened before to me but my memory is flaky, something in my head tells me the tuning info could have the wrong vpid...would that make any sense?

mvpmcx2 will read the stream that NextPVR sends and calculate the audio and video pid's to use independently from NextPVR. Try to play one of these bad channels and telnet to your NMT, issue the following command

cat /tmp/dumpts.txt

and copy the output into another post.

I can see nothing wrong with that information so if there is video stream with pid 320 it should play. Does it play on the PC? Also If you want, I could look at a 10MB chunck made from CutChunk if you want to email it to me or upload it somewhere.

king of sat suggests that info is correct, the channel in question was france 5 on 11591 en.kingofsat.net/tv.php?&b=86&pos=5W&standard=All&ordre=freq&filtre=Clear.

It works ok on both the server an pc client, i'll put a chunk on dropbox later.

Elmo Putney · 2012-04-05, 08:14 PM

20Meg should be available here in about 2 minutes:

Thanks

mvallevand · 2012-04-05, 10:09 PM

Give this a shot, it fixes a bug in the logic on User streams.

Bonne chance.

Great thats fixed that channel, I have also noticed one of the other channels on the same transponder causes the nmt to immediately restart NPVR as soon as live tv is attempted. I did a recording and this plays back ok on the NMT in NPVR mode, is it worth me uploading a chunk?

mvallevand · 2012-04-06, 01:05 PM

That problem sounds like one one were I would need all the logs (one NMT configured). However going by instinct, if the problem station is "France Ã" it might simply be the GBPVR/NextPVR problem with accented characters in filenames. Try using "France O" before going through the bother of the logs.

Yep you nailed it. Thanks Martin
