What videocard do you have?
As I mentioned in this thread http://forum.doom9.org/showthread.ph...56#post1780356 new GTX750 with h265 VLDecoding, http://forum.ixbt.com/topic.cgi?id=10:60902-42 and my Info there.
With LAV CUVID Decoder - DirectShow CUVID Video 0.13 your 1HD sample playing well with unchecked Use HQ DXVA Processing only. With checked it is horrible - worse then decoded by any DXVA1 decoder I tried including CoreAVC 3.0.1 with DXVA Accelaration, with CUDA and None plays well and even KMP not hangs up. This is one more thing why I (and others) want that CUVID (not DXVA) will decode h265 10bit https://devtalk.nvidia.com/default/topic/965840 in XP, 7x64, Linux .... But technical support of nVIDIA worse day by day.
So, it is DXVA issue with NTV+ (like your sample 1HD) channels - some people from http://viaccessfree.su/forum thought this issue due to many GOPs in stream http://webcache.googleusercontent.co...&hl=ru&ct=clnk
IMHO maximum that nevcairiel can do before CUVID will decode h265 10bit - implement mechanism for automatic switching between CUVID and DXVA2 in his LAV Video Decoder. But IMHO it is difficult begining from interface of decoder settings and nevcairiel never do what I ask (
PS. Due to my new videocard my asks about Mainconcept HEVC Decoder support in LAV Splitter and possibility of decoding only key frames in LAV Video Decoder are cancelled by me now )
