|
||||
- nvidia driver (patch availible for 375.39 or 396.24)
|
||||
|
||||
Download driver: https://yadi.sk/d/d87mf0y03WTbb5

|
||||
|
||||
### Install driver 396.24
|
||||
```bash
|
||||
mkdir /opt/nvidia && cd /opt/nvidia
|
||||
wget http://us.download.nvidia.com/XFree86/Linux-x86_64/396.24/NVIDIA-Linux-x86_64-396.24.run
|
||||
chmod +x ./NVIDIA-Linux-x86_64-375.39.run
|
||||
./NVIDIA-Linux-x86_64-396.24.run
|
||||
```
|
||||
|
||||
### Check driver
|
||||
```bash
|
||||
nvidia-smi
|
||||
```
|
||||
|
||||
mkdir ~/nvenc_backup
|
||||
### Patch libnvidia-encode.so (with backup)
|
||||
```bash
|
||||
bash ./patch.sh
|
||||
```
|
||||
|
||||
cd ~/nvenc_backup
|
||||
### Silent patch libnvidia-encode.so
|
||||
```bash
|
||||
bash ./patch.sh -s
|
||||
```
|
||||
|
||||
cp /usr/lib/x86_64-linux-gnu/libnvidia-encode.so.378.13 ~/nvenc_backup/
|
||||
|
||||
wget https://raw.githubusercontent.com/keylase/nvidia-patch/master/patch.sh
|
||||
|
||||
chmod +x patch.sh
|
||||
|
||||
./patch.sh ~/nvenc_backup/libnvidia-encode.so.378.13 /usr/lib/x86_64-linux-gnu/libnvidia-encode.so.378.13
|
||||
|
||||
reboot
|
||||
### Rollback libnvidia-encode.so (restore from backup)
|
||||
```bash

If you experience `CreateBitstreamBuffer failed: out of memory (10)`, then you have to lower buffers number used for every encoding session. If you are using `ffmpeg`, consider using this [patch](https://gist.github.com/Snawoot/70ae403716c698cb86ab015626d72bd4).
