don't be skimpy and post a full log, pls.

also maybe clarify what actually happens. does mpv crash? does it not start? doe it not initialise the context? some lines in a verbose output is not "actual behaviour". we want to know what the problem is.

opengl-angle.log

Most of times I couldn‘t find the differences of the output between ANGLE and WIN (or dxinterop).
But when I tested one hdr source (played to sdr), I got the different outputs.
Could not bind API! always shows in the log if I use the ANGLE, so I wonder if it works correctly and if it is the reason make the different output (in that case).

opengl-angle

opengl-win (It shows the same with d3d11 backend)

[   0.472][v][vo/gpu] Disabling HDR peak computation (one or more of the following is not supported: compute shaders=0, SSBO=0).

that's why. ANGLE doesn't do compute shaders, nor does it do SSBO. Not doing HDR tonemapping the same way as a mode where those things are available is expected behaviour.

In general, you should not use ANGLE if one of the other modes works.

If you want to use Direct3d, I think you should use --gpu-api=d3d11, not ANGLE (which is a layer translating OpenGL ES to Direct3d).

[hooke007]

It solves my confusion. And could I think Could not bind API! is the useless information which actually doesn't affect the output?

[jeeb]

Basically what happens in the following sequence:

[   0.564][v][vo/gpu/opengl] Trying to create Desktop OpenGL context.
[   0.564][v][vo/gpu/opengl] Could not bind API!
[   0.564][v][vo/gpu/opengl] Trying to create GLES 3.x context.

1. Since this is general GL initialization, it attempts to first utilize desktop GL.
2. Could not initialize it (the reason for which is visible from an earlier line, it only has GL ES):

   EGL_CLIENT_APIS=OpenGL_ES
   

3. Then goes for GL ES, and that succeeds with GL ES 3.

Technically the desktop GL attempt is in this case "useless", but would have to check if there's a convenient way of skipping this for ANGLE and/or for GL ES-only things in general..

[Akemi]

since the question has been answered and everything works as intended, i am going to close this.
