CUDA Encoder suddenly stopped working

[gothdir]

Hey guys,

Yesterday I was encoding some video files (like 10 in a row, all same format) the first 5 all worked fine using CUDA Encoder but then at some point it suddenly stopped encoding without any error massage (the progress remained at 0% with 0,0x speed).

I tried with various files and it has stopped working completely I didn't change anything I wonder what happened here and hope someone has a solution.

When you say "it has stopped working completely", do you mean it will no longer convert at all now with CUDA enabled? Even when you restart MediaCoder?
As a preliminary measure, I'd suggest reinstalling first, just to make sure that MediaCoder hasn't logged an error somewhere in the settings. Make sure to tick the "Revert settings" option in the installer.
What graphics card and NVIDIA driver are you using btw?

EDIT: oh, you might also want to try the 32-bit version of MediaCoder and see if that helps if the reinstall of the x64 version doesn't help.

Okay it works again. I reinstalled Mediacoder but that didnt fix it so I also reinstalled my Gfx drivers and that helped. Seems like something broke before. I have a Gtx 660 with the newest drivers.

thank you for your help.

Hey I want to bump this since the problem is back after updating on the newest NVIDIA driver but this time re-installing gfx drivers or Mediacoder doesn't help (even installed 32bit version). After reinstalling Mediacoder, I get the message "no supported acceleration hardware detected".

I checked with other programs (sony vegas pro) and with them CUDA still works fine.

Which version of MediaCoder? Is it the same version as the working one before or did you get the newest version?

It was the version were it worked fine but when the problem started I updates to the newest mediacoder version in hope that it would fix that.

But by now it seems like Nvidia has changed something for CUDA or NVENC because on the Geforce forums a few people had the same problem and on 3Dguru is a moded version of the neweset NVIDIA driver which makes CUDA work again and it made CUDA also work for me too.

Im have absolutely no idea what Nvidia changed, I have no clue about these things but I will link you the thread on the nvidia forums.

This is a post describing what happened with the drivers:

It seems like Mediacoder using some kind of old protocol? But since i have no idea about this stuff Ill leave it up for the professional people.

Getting beyond my technical knowledge there... Also, I'm currently using AMD graphics cards so I can't personally test it.
Maybe you should just reinstall the previous NVIDIA driver you had if you really need CUDA encoding.

Well thanks to the 3dguru mod it works now but maybe the devs can look into it and find a solution which works with official drivers in the future, dont know if they read the forum.
