NPVR 2.5.5 craches due to artifacts in HD recording // Tool for cutting *.ts files

[raceviper13]

Between VLC, Media Player Classic Home Cinema and Windows Media Player, Windows Media Player handles these errors the best without lockups.

I record ATSC from an antenna and use Videoredo's quickstream fix feature to find and remove errors on all my recordings (and convert from .ts to .mpg in the same process). It's not free but I've found it to be a very useful program. It's a frame accurate editor and only re-encodes around the cut points, otherwise it's a lossless stream copy of the audio/video. I use it to fix audio-video sync issues with it's audio delay adjustment (useful for shows on The CW...). I also use it to judge the relative performance of tuners and my antenna system by noting the number of bad audio/video frames removed- Hauppauge's are awesome with typically no bad frames, Dvico Fusion5 and Fusion7 are crap, HDHomerun is crap, Sabrent's cheapie PCI is fine. Note when running quickstream fix, you do lose the NTFS alternate datastream. I'm not sure what impact that would have on nPVR as I watch with MPC-HC. My post processor program uses the alt data for renaming, but it's done before the quickstream fix. Videoredo has a COM interface and sometime soon I'm going to figure out how to automate the quickstream fix with my post processing program. I'm using the older MPEG2 version of Videoredo (v2.5.7.600 Nov 18 2010). Not sure if the newer H264 capable version behaves any different.

If anyone has found any other tools that fix streams, please post.

I'v experienced that some decoders are proun to freeze due to errors in the video stream while others are more resistent. I'm currently using Cyberlink PDVD12 which seems to handle most errors. I think the worst I'v seen is the LAV video decoder (of those that works anyway).

Hi Sub, Hi Reddrawf,

Thanks for the replies, it seems indeed to have something to do with the decoder used for H.264. I've been trying multiple decoders, but my (old) ArcSoft video decoder still seems to provide the best result (apart from the feezes). I tried to update to the latest release, but then I got sound but no image (though the total media theatre trial seems to work with it quite ok). I did not find an awful lot one can configure related to decoders in the NextPVR GUI or are there some hidden settings?

About the PDVD12: I got perfect image, and it doesnt freeze when encountering the artifacts; but unfortunately NextPVR takes about 100% of CPU whereas normally it would take only 40% and it starts stuttering (especially sound during play-back; during live tv both). are there certain settings you are configuring (maybe a combination of that is not optimal)? A certain trial version you downloaded...?

Thanks,
Frederic

Thanks all for the previous replies and suggestions in the thread. Using the PDVD12 decoder and enabling the HW accellaration seems to have solved my issue.

I was about to tell you about the HW acceleration setting , but if the graphic card is not capable of decoding H.256 the decoder resorts to software decoding (older cards usually does not have HW H.264 decoding), but I'm glad to hear your card does.
