... Further information ... MediaPortal is detecting the DVB-T audio type as "MPEG 1" here - incorrect. The audio type on the sat feed is "MPEG 2" - correct. The DVB-T 3+1 feed is correctly detected as LATM-AAC - correct.
Seems like Mediaworks have fiddled with the audio packet headers, and this is causing the audio decoding to be screwed up somehow. I hear this is very easy to do with LATM-AAC...
Examining the PMT with Transedit, the only difference I can see between the DVB-T FOUR/3+1 and C4 is an extra "Audio_Stream" (0x03) descriptor for the audio elementary stream, but most other SD services available here also have that descriptor too...
On a side note, the descriptor for TV3 says it is 4:2:2 chroma video. Since when has that been the case?
I upgraded from Monogram 0.9.5 to 0.9.6, now instead of stuttering the new C4 gives out a jarring kind of buzz. If I fallback to the PowerDVD AAC codec it goes back to stutter. All other channels remain fine.
The only difference I can see on the monogram properties for C4 is 0.9.5 was Low Complexity and 0.9.6 is High Efficiency. I'm not really an audio guru so that could be meaningless.
Same problem here in Tauranga with C42 and MediaPortal 1.1.2. Looks like nothing has been fixed yet. Has the problem been reported to TV3? Is there no problem with freeview receivers?
still running fine in my windows media center.... not to mention in several set top boxes. are you sure it isnt just poorly written codecs that are not interpreting the audio stream correctly?
Cloud spending continues to surge globally, but most organisations haven’t made the changes necessary to maximise the value and cost-efficiency benefits of their cloud investments. Download the whitepaper From Overspend to Advantage now.
Yeah I don't think it's something that needs to be fixed by MediaWorks. I think it needs to be fixed in the Monogram codec. "poorly written" might be a bit presumptuous. Someone needs to contact Redscorpion and provide him with a sample recording of C4.
The PowerDVD7 AAC codec has the same behaviour, for me its Monogram 0.9.5 has stutter, Monogram 0.9.6 has awful buzzing noise and PowerDVD7 has stutter similar to 0.9.5.
There are quite a few newer versions of PowerDVD so maybe one of them is fine but they are expensive.
