Issue #705

Updated by Denis 'GNUtoo' Carikli 4 months ago

Replicant is currently using the fallback Android EGL implementation, which is incomplete. The missing features of this implementation cause multiple issues:
* Slowness issues on devices with slow CPUs
* YUV is not properly supported (only black & white), which forces us to use RGB565 as a preview format on the camera modules. This causes several issues:
* preview-based detection (such as barecodes, QR codes, etc) doesn't work
* panorama feature is broken
* Screenshots do not work
* Previews of the windows in the tasks switcher are missing
* Some applications rely on unimplemented features, such as Firefox, Document Viewer and crash as they are missing

There are patches to use llvmpipe We tried using "Mesa":http://cgit.freedesktop.org/mesa/mesa/ as a replacement, both with Replicant, swrast/softpipe and work swrast/llvmpipe, but it is ongoing to:
* investigate how
too slow to improve the performances of llvmpipe
* investigate how to integrate llvmpipe and libagl at the same time on the device, in a clean way.
be usable.
