MP 1.3.x dshowhelper development (4 Viewers)

So, which version is in 1.30 and have you've heard this before?

It's a modified version of the one in 1.2.3

Have you tried updating LAV ? (the version installed by 1.3.0 is 0.55.2 - the latest version is 0.55.3)

no i haven't yet, i've installed the version supplied with 1.3.0 final, which is i believe 0.55.2.

I'll install tonight and will replace the dshowfilter with the latest one and see if that works better. Tnx!

Okay, i've upgraded to 0.55.3 and replaced the default dshowfilter with the latest one from the FP. I wasn't home yesterday but i've let the TV running, i had 31 droped frames and a clear image when i got back home, so all seems very well.

Maybe it's an idea to replace the default dshowfilter with one from this thread

For a while now ive not ran into problems, atleast it thought i wasn't. I don't really watch that much Live TV, my wife does. She's compaining for a while now the picutre just scrambles and freezes sometimes. Then MePo chucks and eventually crashes. When it is closed i just can open it again and watch live tv.

I've added the relevant logs (atleast i think i have) for now i don't really know what to do. Maybe you could have a look at these? I think the problem occured at 21.11 hr.

There are huge numbers of 'Scheduling sample from the past' messages in evr.log (up to 40s late samples !!), so something is possibly going wrong with the video decoder - is the GPU getting too hot (assuming you are using DXVA) ?

I'm using LAV 0.55.3 and have it to DXVA CUDA (nVidia GFX), it can't be the temp of my GFX, i've already had problems with that and since i cleaned it, it stays at 60 degree's. I'll try and switch back to Microsoft DTV decoder.

Weird thing is, i've never had these problems untill i switched to 1.3.0 final. None of these problems with earlier versions of the 1.3.0 branch.

As far as I remember, there were no changes to dshowhelper and TsReader.ax between 1.3.0 beta and final. The logs you posted are for a 1080i HD channel - does it happen with SD channels ?

I'm using the default TsReader.ax and the latest dshowhelper. We only have HD channels in our listing, but i'll replace a HD channel with SD tonight and see if this happens.

If your CPU is fast enough (and it probably is as it's dual-core + hyperthreading) you could also try using software-only decoding in LAV and see if that is any better behaved with HD.

will try also, the pain is, it runs a couple of hours just fine. So don't know if i can test every scenario tonight

I've changed the LAV from Cuda to Native. I'm seeing lots more dropped packages, but its running steady for about 4 hours now. Can this be explained or is it just something that cant be explained. Is anything changed at 1.3.0 final regarding dropping packages or something? Or could this just be LAV messing things up?

Sorry - I don't understand 'packages' - do you mean frames or samples ?

DXVA2 native uses less GPU resources/performance than CUDA - also CUDA runs the GPU at maximum power state (AFAIK)
