Still having issues with CUVID. It will play a video fine for a good 20 minutes then suddenly start dropping frames like crazy. If I go back I still get the dropped frames. It's weird. It only seems to do it on some files (Mostly anime).

Unless i managed to implement some new bugs, it should be more reliable then before, though.

Can of course always just disable CUVID and use DXVA2 or software decoding, that should in theory resolve those issues.

Quick question, I have a i3 2120 using MPC-HC w Lav Filters/EVR custom renderer. Under Lav Video settings - hardware decoder to use, I have 2 available options, Intel Quicksync or DXVA2 (copy) which option would be best? For BD and Remux playback ?

If your CPU supports it, use QuickSync. A i3 2120 should be fine with it.

I've noticed that the CPU usage is around 3-5% when benchmarking after installing 0.46 and with 0.45 it's at 7-11% and yeilding 3x the result which is interesting. Whether it's highlighting a real issue or not I don't know, if everyone else's system is fine then don't waste any time on it, thanks. |

@Nev Do you know why the Performance of YV12 in Lav Video is lower as the one in FFdshow aren't both the same ?

Hi, Nevcairiel !
LAV Video Decoder not always switch to hardware mode (for ex.: when using DVB Viewer with H.264 streams). In this case, the decoder reports that hardware acceleration is "Available", but not "Active". It happens not quite often, but still... Maybe 'Pure Hardware Mode' option for LAV Video Decoder will solve it? Intel P4@4GHz, GTX560Ti |

There is always a reason when it decides to switch to software mode, if it wouldn't do it, it would potentially mean that playback would fail.
Its certainly possible there is somewhere a small issue that makes it fail when it wouldn't need to, but then that should be fixed and not some mode added that bypasses the checks.

Alexey are you sure the Stream isn't 4:2:2 ? a pure hardware mode wouldn't help in that case as you would only see Garbage
@ Nev DXVA2 Copy back does really well https://forum.doom9.org/showpost.php...&postcount=754 though Intel got the Kernel pressure nicely under control or is this a bug ?

In short, not it shouldn't have any impact, unless i start using new functions.

There is GPU Compute capability, which tops out at 2.1 right now, and specifys which features are supported by the GPU. The CUDA SDK version is just the software version to match, and support only depends on drivers.

Strange issue: using any nVidia GeForce driver since 285.62 and later, cause the problem - image crumbles, tearing into squares, etc. But if I use any earlier driver - there is no problem.
The situation repeating with every new driver release! Any version of LAV Video with CUVID acceleration faces the problem. With CoreAVC Decoder, which uses CUDA too, the same thing! With decoders that uses DXVA everything OK with any driver... Can someone experienced and knows how to fix? Last edited by Alexey1975; 13th February 2012 at 17:42. |
