Watching (or trying to) ABC feed at G3C.   Lav video and madvr renderer.  Picture has momentary freeze every 20 seconds or so. But during commercials, all is well. Hints anyone as what combination of video/audio and renderers to try? I've gone through all that I have with no success. Maybe I need a new one.

VLC plays it perfectly here on my 6 yr old thinkpad laptop.
Intel(R) Core(TM) i7-3720QM CPU @ 2.60GHz
w/ 8 GB RAM, intel 3rd gen graphics (no nvidia graphics here).

The cpu usage showed 90 to 95 percent. Once in a while it hit 100%.. i'm shocked. Don't know how to get that down.

You will probably need at least a quad core cpu similar to mine to be able to decode HEVC 4:2:2 in Software smoothly. Suspect your Nvidia won't offload the CPU at all since it's 4:2:2 and probably doesn't know what to do with it.
Mine is quad core with 8 threads. Why I threw the intel specs at ya.

Did you enabled hardware acceleration in LAV Video settings? With so high CPU usage it seems that HW acceleration is not working. For me DXVA2 (copy-back) mode is offering good performance and stability.
You can find some details here: https://www.team-mediaportal.com/wiki/display/MediaPortal1/LAV+VideoConfiguration

I'll look at the hw acceleration in LAV. Buying a new motherboard with more cpu power may be cost prohibitive. Don't know if the rest of my system would be compatible anyway.  The HTPC was built by AC Radio years ago - RIP.

Went to LAV properties and couldn't find hardware acceleration on/off.   It says: Active hardware accelerator: none.

if you try a different channel, say something hevc 4:2:0 or h264 4;2:0 would that property change, or no?
Not a windows guy, just wondering..

Sounds like the cpu is too slow and video is dropping frames.  Nothing you can do without new hardware.  HW accel won't work for 4:2:2 HEVC with your hardware.   Only new hardware that may HW decode 4:2:2 HEVC is the latest Ice Lake intel chips.  It's in their specs, I have not heard from anyone with an Ice Lake chip to know if it actually works as yet.

Lot's of knowledgeable folks here.  I thank you all.  I must say that over the years, I've had no problem with 4:2:2 feeds.   Only since Two un-named networks added H264 to the mix. Now I have a problem with a quick glitch about every 20 seconds. I guess i need more cpu speed. Time to look for a new PC.

Can find decent used HW that is still capable of being souped up too.
When I bought this Lenovo Thinkpad, it came with below:

Lenovo ThinkPad T430 i5-3320M 2.60Ghz 4GB Memory 500GB Hard Drive, Power Supply and a good battery. $99 + shipping

Replaced CPU with the i7 above, obtained that used also, Added 4 GB RAM, and replaced HD with a new 2TB drive.. wound up with a pretty decent laptop... Certainly better than anything I WAS using.
Without running to the store to grab the latest and greatest spending a ton of cash.
Should be a lot easier to upgrade your desktop than a laptop.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
