Hello. I was just playing around with NVDEC video decoder of my Turing card and I realized that NVCUVID works very nicely under Win 10. It works for legacy codecs like MPEG4 ASP (DivX/ Xvid) which is exposed to LAV Video control panel, but even for not exposed ones like the ancient MPEG1. I was wondering how much trouble is for you to add VP8 to NVCUVID (not DXVA2/D3D11 which could be difficult/ impossible), just NVCUVID. Not that there is some special need for this, but just because Turing NVDEC can accelerate VP8 in HW. NVEncC, a transcoding app which uses both NVDEC and NVENC to accelerate transcoding in HW, can decode VP8 in HW using NVDEC. Thanks! Update: I've just seen that WMV3 also doesn't work for NVCUVID. Weird.

comparing with turned off mixing while have the 2 speakers put far away from each other, it seems that most of the sound are concentrated on one speaker when mixing to stereo. maybe this particular bluray's 5.1ch just happens to be like this. checked and confirmed another bluray's 5.1ch doesn't have sounds concentrate on one speaker when mixing to stereo

Try with a test file like this: https://www.demo-world.eu/download-2...1_lossless.jpg

I reported an issue over in the madVR thread and said I'd give feedback over here.
I completely uninstalled all versions of MPC-HC, LAV filters and madVR then reinstalling from scratch. Then ensured all the internal filters were switched off for x265, x264 and m2ts after installing LAV 0.74.1-18. The result is everything seems to be working perfectly now! I guess it was a mixture of user error and various versions of MPC-HC etc. conflicting. |

No, I do not. The installer is intentionally an one-size-fits-all package for everyone.

I have a video file that probably has an issue with key frames. The symptoms are:
Can LAV be made "compatible" with such files?

I can confirm your issues, LAV Filters for me always had such problems when dealing with HD transport streams. It looks like DirectShow is simply not good at seeking within transport streams...
Just to make sure that your clip was not corrupted I ran it through TSDoctor, and it came out fine without any complaints. My usual workaround for HD transport streams is to repack them into an MKV container. I either use MKVMerge or ffmpeg (using the dmMediaConverter GUI) for this, and the resulting MKVs play with just about any player and have no problems with seeking. Cheers manolito |

This particular stream seems to lack proper recovery information, or has them in a way that FFmpeg doesn't support. No IDR frames, and no Recovery Point SEI. As such, the decoder doesn't know when the image is "clean" and not just artifacts.
I would recommend to report this to ffmpeg, since thats what its based on. This has really nothing to do with being MPEG-TS - although in general its always nice to keep in mind that MPEG-TS is not designed for file-based playback or seeking - its a broadcast format. Thats why Blu-rays keep a seperate index for seeking, which you of course lose if you just take one .m2ts file from the disc.

When I said that I have the same problems with HD transport streams I am talking about the German DVB-T2 broadcasts. They are transmitted with HEVC video and E-AC3 or AAC-LATM audio, and they are not really seekable with DirectShow based source filters.
I did not analyze the transmitted streams if they have IDR frames or Recovery Point SEIs. All I know is that they play well in VLC, but in MPC-HC and Tiny Player they are not seekable. And this time it is not my underperforming hardware, this is on a Core i5 third generation with 8GB RAM under Win7-64. |

Mkvmerge has the option --engage all_i_slices_are_key_frames for such files. But interestingly enabling that option breaks seeking for the resulting mkv, then. |
