igalia / balena-wpe Goto Github PK

hey @psaavedra great on on this :)

I was wondering if we should wait for the weston service to be ready and create the required files here

we've seen issues with xserver block where services might start before the server and the socket is not available even if we use depends_on in the docker-compose file. See an example here

Is it possible to open two separate windows with each one full screen on a separate display?

Various small SPI-based screens are commonly used in conjunction within the Raspberry Pi ecosystem. It would be fantastic to see support for these as well as the existing HDMI monitors.

Describe alternatives you've considered
Loading the relevant overlay and setting the relevant HDMI configuration settings in config.txt does not create a working system.

Because it has a transparent background i guess.

I'm experimenting with using the balena-wpe block to replace the balena-browser block on a rpi that has a small touchscreen that connects to a local grafana website. However, any time the grafana container is updated, the browser requires a hard refresh to make it connect for a new instance id or something. So right now I need to reboot the entire rpi to get the browser to restart.

The wpe webkit setup here has no address or toolbar, nor does it seem to respond to any touch gestures that might initiate a refresh, so I'm out of ideas after playing around for a while. I have some other handy uses for enabling the bookmarks bar, for example, if that were to be possible, and hardcode a bookmarks.html file into the container to use.

In the balena-browser block, I just left it out of kiosk mode so it had the full address/toolbar to allow refreshing, which unblocked my scenarios, though not perfectly of course. :)

Thanks for the project, though, it's so much faster than the X11-based ancient webkit in the balena-browser project!

I had to use igalia/balena-browser-wpe:raspberrypi4-64-79f2c8d

I am able to play videos on vimeo but not on youtube. Could be related to h264 and VP8/9 decoding.

On chromium-browser running on Raspberry Pi, we had to use the h264ify extension to force YouTube to stream H.264 videos instead of VP8/VP9 videos.

@psaavedra Is it possbile to do same in WPE?

It would be great to have the option to disable/hide the cursor, or at least only show it when the mouse is plugged in and moving around. When used for a kiosk, most of the time a cursor is unwanted/unnecessary.

Option to disable the cursor (env var), possibly also the option to not fully disable it, but at least auto hide it after X seconds.

Is your feature request related to a problem? Please describe.
I would like the ability to rotate the entire display 90 or 180 degrees. I've attempted to set the built-in Balena device configuration to rotate the display, but it doesn't appear to work with the Weston/WPE environments.

Describe the solution you'd like
I would either like an option within this project to rotate the display, or a suggestion for how to accomplish this some other way.

Describe alternatives you've considered
I've tried the Balena configuration option for rotating the display on a Raspberry Pi

Additional context
I'm using a Raspberry Pi 4 with the most recent BalenaOS

I thought WPE provided a web interface to configure url?

The default values for env vars noted in README might be wrong:

likewise for

• WPE_COG_PLATFORM_FDO_VIEW_HEIGHT: 768 vs 720
  

  balena-wpe/wpe/cog-fdo

  Line 9 in 573e8c5

  export COG_PLATFORM_FDO_VIEW_HEIGHT=${WPE_COG_PLATFORM_FDO_VIEW_HEIGHT:-768}

• Not sure about WPE_ENABLE_INSPECTOR_SERVER but it seems it will default to 1 ?
  

  balena-wpe/wpe/cog-fdo

  Line 14 in 573e8c5

  export WPE_ENABLE_INSPECTOR_SERVER=${WPE_ENABLE_INSPECTOR_SERVER:-1}

• CPU_SCALING_GOVERNOR might default to performance ? but readme says ondemand
  

  balena-wpe/wpe/wpe-init

  Line 7 in 573e8c5

  CPU_SCALING_GOVERNOR=${CPU_SCALING_GOVERNOR:-performance}
