I was able to convert MP4 to GIF with ffmpeg with the following commands on Ubuntu 22.04:
ffmpeg \

First, connect to Ubuntu Live with SSH:
sudo apt-get update
sudo apt-get install ssh
sudo passwd ubuntu
List disks and partitions:
sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-13 g++-13
ll /usr/bin/gcc-13
ll /usr/bin/g++-13
update-alternatives --display gcc
ll /etc/alternatives/g*
sudo update-alternatives --remove-all gcc
sudo update-alternatives --remove-all g++
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-13 10 --slave /usr/bin/g++ g++ /usr/bin/g++-13
g++ --version
gcc --version
I cloned the repository, created build directory, set environment variables and run CMake:
git clone https://github.com/baldurk/renderdoc.git
cd renderdoc/
mkdir build-android
cd build-android
export JAVA_HOME=~/dev/repos/graphicsprofiler/tools/buildtools/jdk
export ANDROID_SDK=~/dev/repos/graphicsprofiler/tools/buildtools/android
export ANDROID_NDK=~/dev/repos/graphicsprofiler/tools/buildtools/android/ndk-bundle/android-ndk-r20b
export PATH=$PATH:$JAVA_HOME/bin
cmake -DBUILD_ANDROID=On -DANDROID_ABI=armeabi-v7a ..
I followed this guide, run the following command from WSL:
ssh -L 59000:localhost:5901 -C -N -l dmitriano $VNC_IP
and was able to connect with UltraVNC client:
Installed FireFox browser as described here.
(more…)I simply installed:
sudo apt install ubuntu-desktop-minimal -y
sudo apt install xrdp -y
systemctl status xrdp
and was able to connect with Remote Desktop from Windows as root user:
