Topic: Windows 10 - FFDshow crashing when using svp

since about a week ago, ffdshow has started crashing whenever i start a video with svp running, either 3.1.7 or 4 TP.

mpc-hc crashes out and i get a crash log informing me that it's ffdshow that has crashed

i have the video and audio filters blocked in mpc-hc, and the raw video preferred - since without it, you can't use svp.
if i try to play a video with svp enabled, mpc-hc consistently crashes an i'm unable to until i disable svp

i'm using the internal lav filters from the latest nightly mpc on an nvidia 970gtx.

has anyone else experienced this or knows why it would be happening?

Did you try to disable GPU-acceleration in SVP or to disable CUVID in LAV decoder?

Re: Windows 10 - FFDshow crashing when using svp

i had tried it on dxva2 copy-back, but not without gpu acceleration.

i did just try it though and with no gpu-accel and dxva i still get the same crash.
and i just tried with no hardware-acceleration and no gpu-acceleration, sadly the result was no different.

What version of MPC-HC do you use? It must be x86 version

Re: Windows 10 - FFDshow crashing when using svp

im currently using the 1.7.9.145 (nightly) x86.

i'll try a few previous nightlies and the current stable branch and report what i find

Re: Windows 10 - FFDshow crashing when using svp

just tried the last 10 nightly build as well as the current stable 1.7.9 x86, as well as the standalone lav filters instead of the internal ones, all with the same result, as soon as the video starts, mpc-hc crashes blaming ffdshow

one interesting thing to note, if i have svp disabled and start the video, it's fine, but crashes as soon as you enable svp. is svp asking ffdshow to something unusual maybe? could it be related to the OpenCL 1.2 issue that you linked earlier?

edit: just checked and i have the opencl.dll version 1.2.11.0 if that helps explain anything

Re: Windows 10 - FFDshow crashing when using svp

well, i narrowed it down to a couple of things.

i uninstalled svp 3.1.7 and 4 TP25 and ffdshow.

i then reinstalled ffdshow, making sure that avisynth scripts serving and application plugins were enabled, and then svp 3.1.7 installing avisynth 2.5.8 MT.

and behold, it works again.

so i'm guessing either one or more of those compenents were misbehaving/not present ( even though they should have been ) but it now works.

should look more closely at what installed and what's not next time...

incidentally though, is it possible for svp to know that either avisynth is missing or that ffdshow isn't going to respond to it's requests and inform the user? might make debugging this issue simpler next time

Congratulations! smile

I followed what you did to fix it but no luck for me.  mpc-hc video freezes on the first frame while the audio keeps playing

Re: Windows 10 - FFDshow crashing when using svp

Mine also crashes in SVP 3.17 or 4 (latest build) on Windows 10 x64 using an NVidia GTX 970, unless I disable GPU acceleration.

I watched a couple movies so far, looks decent. I can't wait until the player matures and doesn't crash and works with GPU acceleration too. Good luck and good job so far!

Re: Windows 10 - FFDshow crashing when using svp

RLBURNSIDE

No, this more like about driver's issue than SVP itself. In NVidia, there is change in NVidia since certain driver version number. (I think it's about NVidia trying to change their OpenCL or whatnot) so it will break/crash the software the relied on OpenCL.

Updating the driver won't help.

Disclaimer: I don't have an NVidia GPU tongue
