* vo_opengl: move shader handling to raGravatar wm42017-08-05
| | | | | | | | | | | | | Now all GL-specifics of shader compilation are abstracted through ra. Of course we still have everything hardcoded to GLSL - that isn't going to change. Some things will probably change later - in particular, the way we pass uniforms and textures to the shader. Currently, there is a confusing mismatch between "primitive" uniforms like floats, and others like textures. Also, SSBOs are not abstracted yet.
* vo_opengl: organize ra PBO flag slightly differentlyGravatar wm42017-08-05
| | | | | | | | Instead of having a mutable ra_tex field (and the only one), move the flag to struct ra, since we have only 2 tex_upload user calls anyway, and both want the same PBO behavior. (At first I considered making it a RA_TEX_UPLOAD_ flag, but why bother. PBOs are a terribly GL-specific thing, so we can't expect a reasonable abstraction of it anyway.)
* vo_opengl: make OSD code use ra for texturesGravatar wm42017-08-05
| | | | | | | | | | | | This requires a silly extension to ra_fns.tex_upload: since the OSD texture can be much larger than the actual OSD image data to upload, a mechanism for uploading only to a small part of the texture is needed. Otherwise, we'd have to realloc/copy the data, just to pad it, and then pay for uploading the padding too. The RA_TEX_UPLOAD_DISCARD flag is not interpreted by GL (not sure how you'd tell GL about this), but it clarifies the API and might be helpful if we support other backend APIs in the future.
* vo_opengl: split utils.c/hGravatar wm42017-08-05
| | | | | | | | | Actually GL-specific parts go into gl_utils.c/h, the shader cache (gl_sc*) into shader_cache.c/h. No semantic changes of any kind, except that the VAO helper is made public again as part of gl_utils.c (all while the goal for gl_utils.c itself is to be included by GL-specific code).
* vo_opengl: osd: use new VAO mechanismGravatar wm42017-07-22
| | | | | | | In addition to using the new VAO mechanism introduced in the previous commit, this tries to keep the OSD code self-contained. This doesn't work all too well (because of the pass and CMS stuff), but it's still better than before.
* vo_opengl: osd: refactor and simplifyGravatar wm42017-07-22
| | | | | | | | Reduce this to 1 draw call per OSD pass. This removes the need for some annoying special handling regarding 3D video support (we supported duplicating the OSD/subtitles for side-by-side 3D output etc.). Remove the unneeded texture sampler uniform thing.
* vo_opengl: remove caching GL_MAX_TEXTURE_SIZE valueGravatar wm42016-07-03
| | | | | | | No real need to cache this, and we need fewer fields in the OSD part struct. Also add logging for when the OSD texture is reallocated.
* vo_opengl: move PBO upload handling to shared codeGravatar wm42016-07-03
| | | | | | | | | | | | | This introduces a gl_pbo_upload_tex() function, which works almost like our gl_upload_tex() glTexSubImage2D() wrapper, except it takes a struct which caches the PBO handles. It also takes the full texture size (to make allocating an ideal buffer size easier), and a parameter to disable PBOs (so that the caller doesn't have to duplicate the gl_upload_tex() call if PBOs are disabled or unavailable). This also removes warnings and fallbacks on PBO failure. We just silently try using PBOs on every frame, and if that fails at some point, revert to normal texture uploads. Probably doesn't matter.
* vo_opengl: remove OSD bitmap packingGravatar wm42016-07-01
| | | | It's packed in the OSD common layer already.
* sub, vo_opengl: use packed sub-bitmaps directly if availableGravatar wm42016-06-17
| | | | | | | | | | | | | | | | | | The previous few commits changed sd_lavc.c's output to packed RGB sub- images. In particular, this means all sub-bitmaps are part of a larger, single bitmap. Change the vo_opengl OSD code such that it can make use of this, and upload the pre-packed image, instead of packing and copying them again. This complicates the upload code a bit (4 code paths due to messy PBO handling). The plan is to make sub-bitmaps always packed, but some more work is required to reach this point. The plan is to pack libass images as well. Since this implies a copy, this will make it easy to refcount the result. (This is all targeted towards vo_opengl. Other VOs, vo_xv, vo_x11, and vo_wayland in particular, will become less efficient. Although at least vo_vdpau and vo_direct3d could be switched to the new method as well.)
* vo_opengl: rename glUploadTex, drop unused parameterGravatar wm42016-05-23
| | | | | | | | Rename it to get out of OpenGL's namespace. The gl_ prefix is used by other mpv functions, but no OpenGL ones. The "slice" parameter was never actually used, and all callers passed 0 for it.
* vo_opengl: unify PBO and normal OSD texture upload pathGravatar wm42016-05-23
| | | | | | | | | | | | | The main change is actually that e first copy to a "staging" memory frame, and then upload this at once. The old non-PBO code called glTexsubImage2D for each OSD sub-bitmap. The new non-PBO code path is a bit faster now if there are many small sub-bitmaps (on Linux/nVidia). It's also a bit simpler, so this is a win. (Although I don't particularly appreciate the mixed normal/PBO texture code.)
* vo_opengl: make PBOs work on GLES 3.xGravatar wm42016-05-23
| | | | | | | | | | | | | For some reason, GLES has no glMapBuffer, only glMapBufferRange. GLES 2 has no buffer mapping at all, and GL 2.1 does not always have glMapBufferRange. On those PBOs remain unsupported (there's no reason to care about GL 2.1 without the extension). This doesn't actually work on ANGLE, and I have no idea why. (There are artifacts on OSD, as if parts of the OSD data weren't copied.) It works on desktop OpenGL and at least 1 other ES 3 implementation. Don't enable it on ANGLE, I guess.

* vo_opengl: reorganize texture format handlingGravatar wm42016-05-12
| | | | | | | | | | | | | This merges all knowledge about texture format into a central table. Most of the work done here is actually identifying which formats exactly are supported by OpenGL(ES) under which circumstances, and keeping this information in the format table in a somewhat declarative way. (Although only to the extend needed by mpv.) In particular, ES and float formats are a horrible mess. Again this is a big refactor that might cause regression on "obscure" configurations.
* vo_opengl, osd: allow osc.lua to react faster on resizesGravatar wm42016-03-21
| | | | | | | | | Glitches when resizing are still possible, but are reduced. Other VOs could support this too, but don't need to do so. (Totally avoiding glitches would be much more effort, and probably not worth the trouble. How about you just watch the video the player is playing, instead of spending your time resizing the window.)
* Change GPL/LGPL dual-licensed files to LGPLGravatar wm42016-01-19
| | | | | | | | | | | Do this to make the license situation less confusing. This change should be of no consequence, since LGPL is compatible with GPL anyway, and making it LGPL-only does not restrict the use with GPL code. Additionally, the wording implies that this is allowed, and that we can just remove the GPL part.
* vo_opengl: remove gl_ prefixes from files in video/out/openglGravatar Niklas Haas2015-09-09
This is a bit redundant with the name of the directory itself, and not in line with existing naming conventions.
