H264 1080i playback problems - thinks it's mpeg2

[BigMoose]

GBPVR always picked the right audio channel for me (and still does - but maybe that's cause I set the audio id myself in the scan.cache) but npvr always picks the narrative which is annoying when it is actually a real narrative - not to mention a complete waste of a DD5.1 amp for the few things broadcast in DD5.1.

Thanks again for the logs. I've tried using CoreAVC and I can now play the recorded .ts files back. So it must be something to do with MS H264 win7 decoder and how npvr uses it. Whatever it is, it works OK in GBPVR but not NPVR. Which is a pain as the MS decoder is much better on my setup for BBC HD with VBR. I get corruptions with CoreAVC every now and then on BBC HD which I dont with the MS decoder. Sub, is there something npvr is doing that this codec doesn't like? Or can you play back .ts H264 files with it ok? (I think you have win7 thus have the codec?)

It played for me, but I checked and found I was using the ArcSoft H.264 decoder. I tried the Microsoft decoder and got only a black screen. I havnt had time to investigate though - busy with day job stuff today.

No worries re time, I understand the day job getting in the way! They have a habit of doing that... I'm on holiday next week so it'll be a while before I get round to playing with it further. I'm glad it's not just me though so there is something up with this decoder and npvr. I might try the ArcSoft one again as I think it's meant to work with ATI and dxva, but I think I tried it before and didn't get particularly good results.

Hi Sub, wondering if you've managed to solve the problem with the MS H264 decoder and recorded playback? I've tried ArcSoft, PDVD, CoreAVC and only the MS one gives acceptable results on the BBC HD channel now they use VBR.

I'm not really sure what I could do differently about how the decoder is being used. Do that recording that shows as black in NPVR with MS decoder give you real video in GBPVR?

[BigMoose]

Yeah, GBPVR plays fine with the MS decoder. Here's a GBPVR log.

Excellent, 1.5.24 has fixed the problem, thanks sub! Only remaining problem is that it still insists on picking the NAR audio channel for any channel where an mpeg1 NAR and AC3 audio streams exist (both in liveTV and playing back .ts recordings). Think this is really all that's stopping me being able to move from GBPVR to NPVR - everything else seems to work very well.

I'm away from my development machine the next couple of days, but bump the thread after that and I'll take another look.

@Sub: What audio decoder is NPVR using for MP3-sound? I have sevral HD-channels that broadcast sound in MP3, and I'd like to configure the decoder to remix it to surround sound.

I have ffdshow configured for mpeg audio and it has options for surround.
