Blender on the Raspberry Pi (44)
Welcome to the special Raspberry Pi edition of using Blender (v2.79) for video editing. As of June 2020, it doesn't work out of the box, so we cover three important items here:
0:00 Intro
0:45 Prevent crashes
2:08 Rendering video & audio separately
4:25 Combining video & audio into a single movie file
This video was recorded on a Raspberry Pi 4B with 4GB RAM.
** Here are the terminal commands you will need **
Open a terminal and run this command to start Blender:
blender --debug
This prevents Blender from crashing when you try to load a video file (with the message "Bus error")
To combine your video and audio renders into a single movie file, use FFmpeg.
Assuming that your video file is named "output.mp4", and your audio file is named "audio.flac", and you want to create a final movie file called "muxed.mp4", here is the command to run:
ffmpeg -i output.mp4 -i audio.flac -c:v copy -map 0:v:0 -map 1:a:0 muxed.mp4
** The new "Bullseye" Raspberry Pi OS has Blender v2.83 in the repos. To use it, you can go to your console and run this:
LIBGL_ALWAYS_SOFTWARE=1 blender
I haven't tried doing anything much with it yet except some basic 3D modeling (which was painfully slow). Here's a reference on that command: https://forums.raspberrypi.com/viewto...
