Firefox 71 Landing Wayland DMA-BUF Textures Support

my only current gripe with FF on Wayland is that when it starts the screen becomes corrupted. The solution is to switch virtual desktops back and forth and then works fine.

Really? The patent is about the hardware acceleration, not on the library used for decoding? mg

With the move to less patent-encumbered codecs like VP9 and AV1 it's less common that you actually have fixed function hardware that supports decoding your codec.

No, you know what is funny, that you complain about something you clearly do not understand. The wayland dmabuf support is a requirement for video decoding to avoid having to avoid unnecessary copying of data to and from the GPU. So you are complaining about them actually getting closer to the thing you want.

Will this mean Firefox can work in a zero-copy mode? IE it only works directly with the GPU memory buffer and that exact same buffer (at the exact same GPU memory address) is referenced by the Wayland compositor when compositing a fullscreen image to be displayed on the monitor?
... so instead of:
Firefox edits system RAM buffer -> Firefox copies RAM buffer to GPU buffer -> Desktop compositor copies GPU buffer to its own memory region -> Desktop compositor creates fullscreen image to display
... you get:
Firefox edits DMABUF, GPU buffer -> Desktop compositor creates fullscreen image to display based on that buffer (and others)

The Wayland support is shaping up nicely for Firefox. The last months there have been very much progress. Now you can run Firefox on Wayland it works pretty well, even though it doesn't work perfectly yet.
