VLC on RaspberryPI0w2 with framebuffer only

Description

Want to use vlc without X11 and run it on fb only.

Steps to reproduce the issue:

Add vlc to IMAGE_INSTALL
Set machine to raspberrypi0-2w
Do not set x11 or wayland in DISTRO_FEATURES
Remove vc4graphics from MACHINE_FEATURES and use userland
Run build using kas-container v3.0.2 https://raw.githubusercontent.com/siemens/kas/3.0.2/kas-container

Describe the results you received:

We are using custom layer which uses meta-raspberrypi. Previously our project used omxplayer but we were told to try and switch to VLC as it gets more support https://github.com/agherzan/meta-raspberrypi/issues/1102.

rpidistro-vlc got some switches on x11 https://github.com/agherzan/meta-raspberrypi/blob/master/dynamic-layers/multimedia-layer/recipes-multimedia/rpidistro-vlc/rpidistro-vlc_3.0.12.bb#L53 so we try build it to run on fb. What we got are following build errors:

First is that running bitbake ffmpeg start ffmpeg from poky/meta

When force to build rpidistro-ffmpeg in return we get

ERROR: Nothing PROVIDES 'rpidistro-ffmpeg'
rpidistro-ffmpeg was skipped: incompatible with host arm-project-linux-gnueabi (not in COMPATIBLE_HOST)

This is probably because of https://github.com/agherzan/meta-raspberrypi/blob/master/recipes-multimedia/rpidistro-ffmpeg/rpidistro-ffmpeg_4.3.2.bb#L193, should not be there just COMPATIBLE_HOST:rpi = "(.*)" - so the same for https://github.com/agherzan/meta-raspberrypi/blob/master/dynamic-layers/multimedia-layer/recipes-multimedia/rpidistro-vlc/rpidistro-vlc_3.0.12.bb#L157 - after that rpidistro-ffmpeg starts build but fails on opengl check (mesa-gl successfully build with this fix https://github.com/agherzan/meta-raspberrypi/issues/987#issuecomment-1020306027)

@EasyIP2023 looks like you did majority of work for VLC support in meta-raspberrypi. Maybe you will be able to support here?

@TomaszAIR Does running it like it shows in Usage example: not produce output? https://meta-raspberrypi.readthedocs.io/en/latest/extra-build-config.html#raspberry-pi-distro-vlc.

Also, may you add some of the vlc flags you are testing with? My main concern was the use of mmal_vout plugin.

@EasyIP2023 thanks for quick response.

The problem is that I am not able to compile VLC for rpi0w2 without x11. The revision used of meta-raspberrypi is fc5f80a47ed7761509ac0700c81581c97dfe135a. I will test from dropping off our custom layer and test rpi0w2 build just with meta-raspberrypi, x11 removed from DISTRO_FEATURES and DISABLE_VC4GRAPHICS set to 1.

Will post the results.

@TomaszAIR Thanks for helping on finding this. Appears the issue is with https://github.com/RPi-Distro/ffmpeg/blob/pios/bullseye/configure#L6455. ./configure is looking for <recipe-sysroot>/usr/include/ES2/gl.h which doesn't exists. It does however exists in <recipe-sysroot>/usr/include/GLES/gl.h.

Also appears I didn't include virtual/libgles2 in PACKAGECONFIG[opengl] = "--enable-opengl,--disable-opengl,virtual/libgl".

Will try to add patch soon that fixes ffmpeg configure bugs.

Hey @TomaszAIR when you get the chance can you try out https://github.com/EasyIP2023/meta-raspberrypi/tree/testing. Contains relevent open MR's + rpidistro-vlc version update.

The VLC recipe update is still a WIP running into a pretty nasty bug when testing. It has the mmal_vout plugin like we all want. You should be able to at least compile both ffmpeg and vlc without x11 or wayland distro features enabled on branch. Just my update will have more time next week on vlc upgrade.

@TomaszAIR Thanks again for identifying this whenever you have time may you try https://github.com/EasyIP2023/meta-raspberrypi/tree/testing-two.

I'm able to build and see output without both x11 and opengl being defined in DISTRO_FEATURES

@EasyIP2023 First of all, sorry that it took so long for me to check this out. Second of all.. Thank you! It is working now. I can confirm that using vlc compiled from https://github.com/EasyIP2023/meta-raspberrypi/tree/testing-two on my rpi0w2 with framebuffer only allow me to start video on screen connected via HDMI.

Are those changes already merged into master of meta-raspberrypi?

Also, got one minor issue. In my build I do not use libcamera so I cannot build if I do not remove libcamera_%.bbappend from dynamic-layers as it does not have recipe to use with. Can it be handled in some way?

@TomaszAIR. The updates to the rpidistro-{vlc,ffmpeg} are merge into master.

BBMASK is your friend. https://docs.yoctoproject.org/ref-manual/variables.html?highlight=bbmask#term-BBMASK

Thanks. I am not used to to use BBMASK. Will try that. Looks like vlc works so I think we can close that issue
