im using Hardware Acceleration on Opera,
and NVIDIA propietary drivers 550VLC has the same problem...
using OpenGL, X11, Xwindow Outputs...VDPAU is the Only output that works,
but Opera does Not allow to select the Video Driver. -

VLC has "Auto" Output module,
because some video files do Not play with some Outputs, do Not decode properly,OpenGL has 3 different versions,
but works with most video codecs....problem is that OpenGL Sharpness enhancement does Not work,
maybe its a driver problem, or a software problem Not adjusting Sharpness code to different Output modules.i guess each output "X11, OpenGL, VDPAU, etc.." has a different API call to do Sharpness,
but API call does Not change when a different Output is selected,
api call is Not recognized by a different driver.VDPAU detects VLC sharpness api call, and works,
but cannot play all video files, cannot play all codecs.same happens with Opera,
Opera default Video Driver is Probably OpenGL, because OpenGL is cross platform, and plays almost all video files.
but Lucid "Sharpness" api call is Not detected by OpenGL output decoder.Thats the only theory i have to explain, why VDPAU works, and Not others...
but thats Not the whole story.....
when using intel integrated graphics, decoding is done by CPU, Not GPU,
and Sharpness works ok done by CPU, but eats a lot of CPU.when GPU is decoding, CPU is very low.
Sharpness "Lucid" api call is different and does Not work with OpenGL / GPU.
but Lucid works using CPU decoding "high CPU usage".Same as VLC.
Firefox type browsers are done with Mercurial,
Chromium type browsers are done with Electron...i dont know Opera what crossplatform mainframe is using for compiling.
dont know if Opera is using libSDL2 libSDL3 ?all i know is that Opera has the same problem as VLC,
Sharpness / Lucid does Not work with OpenGL output Video driver / GPU decoder.
i guess the problem is an Api call mismatch caused by using a platform that allows cross-compiling same code to different OS.
the Sharpness Api call is different:
CPU output module / render / decoder
vs. OpenGL, X11, and others, except VDPAU .
VDPAU has same Api call as CPU decoder "compatible" but works with GPU. "low cpu usage".i dont have an AMD video card to test AMD driver.
