[QUOTE="velis, post: 726580, member: 96429"] Man, I really need to set up VPN to home :( Yeah, sorry, forgot to attach the .rar. Will do immediately when I get home (in 7 hours). Edit: attached One further observation: This mostly drops in HDTV signals - or better said: when CPU usage is ~100% on all cores. It seems that the grabber thread will normally grab the packets, but the mm thread can't get them because it's blocked by too much CPU usage. Pretty much every stutter is reflected by additional buffer allocation in the grabber thread. Need to verify what happens if I also set mm thread to time_critical. Two expected outcomes: 1. mm thread is blocking and grabber thread will not be able to grab packets == stutter 2. TvService will successfully get all its CPU cycles and do its work. Only the client will drop video frames due to inability to render fast enough Naturally the second outcome is much preferred :D Edit2: I don't get it. Playing IPTV with 8Mbit SDTV MPEG2 signal takes <10% of my CPU, but playing a 24Mbit HDTV MPEG2 totally stumps my CPU :( So for 4x the pixels I get ~10x CPU usage :S [/QUOTE]
