Re: MediaCoder + NVENC SDK 5.0

I'm a new user and I'm trying to convert .m2ts into h.265 using GPU. After I checkmark GPU, MediaCode automatically chooses NVENC and H.264 (which I then change back to H.265). I have two Nvidia GTX 970 in SLI and I'm using the newest driver 350.12 and I installed CUDA Toolkit 7 (but I only chose to install the CUDA toolkit instead of everything).

When I try to encode, I get error 014. I can encode using the x265 encoder and it uses my CPU but speed is 0.51x (using Medium preset). I would like to use the GPU for faster encoding for H.265. Please advise.

Hello everyone,

I am encode my .mpg file to x265 with nvenc and my GTX980. See attached picture. I just put B-frames to 0 and everything worked.

NVENC SDK 5.0.1 is used, so NVIDIA GPU driver 347.09 or above is required. The latest version of SDK has added support for HEVC (H.265) encoding on GM20x GPUs (GTX980 and future Quadro/Tesla/GRID platforms based on GM20x GPUs).

To test NVENC with MediaCoder, please install the latest MediaCoder Full Edition and install the following update.
If I download the LATEST version do I still need to download the "update" or am I good?
The update never downloads - mirror troubles or something?

Hello!

I have the same problem. I still gets Error 14 when I try to encoded using NVENC to H.265 format. I don`t know if this encoder is present in the newest version of Media Coder Premium from 18th Aug 2015, because the error 14 says that the encoder is absent.

My Input file is MPEG-4 20.7 Mbps bitrate FULL HD 50p

I have the following parameters set:

a) Video tab
Rate Mode: Average bitrate -> Video Bitrate 12000 kbsp
Format: H.265
Encoder: NVENC GPU checked; Auto unchecked
Source disable; Auto checked and System also checked

b) Tasking tab
Parallelize: 1 Job
Priority: Auto
Segmental Video Encoding checked
Cores Allocation: Video Encoder chosen from the list

c) Audio
Copy audio checked

d) Container tab
Container: MKV
Multiplexer: Auto Select

My hardware:
Intel i7-3930 CPU
GeForce GTX 570

My drivers:
The newest version of GeForce Game Ready Driver installed (355.60 from 13th Aug 2015)


Please help me because I have more than 300 videos to convert to H.265 and now this software is unusable for me.

Regards

I am having error 14, with a fresh installation.
I am having NVIDIA 940M, any clue? do I need to install any NVENC SDK or something ?

Currently we have an option for Constant QP which is my preferred encoding method, but it is a fixed value. The encoder supports different values for i-frames and p-frames.
Can we have something like this :

Code: Select all

--cqp <int> or encoded at a fixed quantization amount
          <int>: <int>: <int> default: <I>: <P>: <B> = <20>: <23>: <25>
