Unable to Install Raspbian - Debian Buster 10.11 based

[iriki]

Hello. I'm on Raspbian Debian Buster:

pi@raspberrypi:~/stremio-shell $ cat /etc/debian_version 10.11

... but I'm having issues installing the newer version:

pi@raspberrypi:~/stremio-shell $ sudo dpkg -i /tmp/Stremio-4.4.142-armhf-32-bit/stremio_4.4.142-1_armhf.deb Selecting previously unselected package stremio.

Try 'apt --fix-broken install' with no packages (or specify a solution). pi@raspberrypi:~/stremio-shell $

Note that I added

deb http://ftp.us.debian.org/debian/ buster main contrib non-free deb-src http://ftp.us.debian.org/debian/ buster main contrib non-free

as stated on the ticket #30 .

Can anyone help? Many thanks in advance.

A couple of issues. Looks like you have not followed the README completely.

1. Why do you have a stremio-shell folder ?
2. The installation command is not what I have given. (Did you see 5. under https://github.com/shivasiddharth/Stremio-RaspberryPi#installation-using-binaries ?)
3. Why is the binary in the tmp folder ?

Getting stremio to work on Pi is tricky. It took me over 50 attempts to figure out the exact step-by-step procedure. If you deviate from the exact steps, its not going to work.

Yay it's working, I feel ashamed and I'm sorry I haven't followed all the instructions thoroughly, now it's working, albeit it presents a bit of tearing when there's a lot of horizontal movement.

Fix for screen tearing

Open a terminal and run

sudo raspi-config     

In that, Navigate to Advanced Options -> Compositor -> xcompmgr composition manager -> Choose “No”

Make sure to increase the GPU memory also.

[shivasiddharth]

You need to do a restart after that.

Thanks, but xcompmgr composition manager was already disabled on my Buster installation.

After much fiddling, I found the cause (and also the fix!):

Chromium had Video acceleration disabled. Go to chromium://gpu and check under "Video decode". Mine was on software rendering. So I found this tutorial and followed the steps, but unfortunately on Fig.5 while trying to activate Hardware-accelerated video decode, that option was "Not available on your platform".

After more searching, I found out that starting chromium with the flag --enable-features=VaapiVideoDecoder the hardware video decoding was now enabled in chromium://gpu. Woh-woh!

Now I needed a way to pass that flag back to Stremio. After even more searching, I found that one can pass that command line options inside a file in your home dir called ~/.chromium-browser.init. This way it will be picked up by all Chromium instances.

CHROMIUM_FLAGS="--enable-features=VaapiVideoDecoder"

Now when starting Chromium normally, the Video Decode: Hardware accelerated should now appear in Green and ready to rock! The video playback on Stremio is now also butter-smooth and I can no longer see any tearing whatsoever. Hope this helps anyone with the same issue.

Hello again. After reinstalling Debian Buster 2021-12-02 version, the upper fix no longer worked. After much fiddling, the flags now need to be set in another location, this time at the end of the file /etc/chromium.d/default-flags, like so:

export CHROMIUM_FLAGS="$CHROMIUM_FLAGS --enable-features=VaapiVideoDecoder"
export CHROMIUM_FLAGS="$CHROMIUM_FLAGS --ignore-gpu-blocklist"

Now the flags will be picked up automatically by any instance of chromium, including the one ran by Stremio. Enjoy flicker-free experience!
