Cameron Gutman 05ef938e2c Add support for LTR ACK control messages 2026-01-20 21:54:14 -06:00
Cameron Gutman 1e825c85e5 Optimize render to decode fence usage to reduce pipeline bubbles 2026-01-19 18:38:38 -06:00
Cameron Gutman a0a4c1ea83 Use decoder texture binding by default when using separate devices 
This significantly improves performance on Ryzen 3300U and should generally perform equal or better everywhere.

This decoder->SRV path has been prone to driver bugs, so we may need to adjust this logic if driver issues crop up.
 2026-01-19 16:46:50 -06:00
Cameron Gutman b5e7dec378 Fix D2R fence initial value 
Fixes synchronization of the first decoded frame
 2026-01-19 16:10:02 -06:00
Cameron Gutman adbd19e6fa Remove the previous frame rendered fence 
- Waiting on this fence prior to rendering introduces pipeline bubbles which can impact rendering performance on low-end GPUs
- Pacer simply waiting to release the previous frame until after the current frame is rendered already means any decoder stall should be very short
 2026-01-19 16:01:50 -06:00
Cameron Gutman 02a86167da Disable separate decoder devices for non-Intel FL11.0 GPUs 2026-01-19 15:08:14 -06:00
Cameron Gutman a739c1cef8 Fix D3D11 fence sharing without monitored fence support 2026-01-19 14:53:23 -06:00
Cameron Gutman f6e08f8a43 Use separate render and decode D3D11Devices 
See #1424
 2026-01-19 14:25:08 -06:00
Cameron Gutman 218ffc2d55 Set explicit scaling mode for all SDL textures 2026-01-17 02:34:54 -06:00
Cameron Gutman 0f49dca4c0 Use GL_NEAREST when possible without degrading quality 2026-01-17 02:23:28 -06:00
Cameron Gutman 30274f3ae8 Don't keep the dummy renderer alive for EGLRenderer's lifetime 
At best, it doesn't do anything other than some queue some viewport
changes via SDL_RendererEventWatch(). At worst, it can race with
the render thread and cause trouble.

Cameron Gutman d865c77975 Crop the incoming frames if they deviate slightly from the expected size 
Fixes #1466
 2026-01-11 20:58:48 -06:00
Cameron Gutman cd13910e6c Add support for YUV 4:4:4 in DXVA2 
We get it basically for free now that we let FFmpeg handle the heavy lifting.
 2026-01-11 20:55:46 -06:00
Cameron Gutman b8e9262b1b Replace deprecated DXVA2 initialization with standard hwaccel init 
- Avoids requiring a hardcoded number of frames (and creating surfaces ourselves)
- Removes a ton of unnecessary code that's duplicated in FFmpeg
- Supports dynamic frame sizes, formats, and color conversion
- Supports frame cropping in FFmpeg
 2026-01-11 17:46:13 -06:00
Cameron Gutman c14ebb1ad7 Adjust buffer count for hwaccel and v4l2m2m decoders 
- For hwaccel decoders, don't depend on FFmpeg's 4 working surfaces.
  The decoders might need one or more of them internally.

- For V4L2M2M decoders, adjust the buffer counts to match our needs
  and requirements regarding Pacer-held frames.
 2026-01-11 14:18:22 -06:00
Cameron Gutman d3957b3cbb Fix race condition where a separate test decoder could ingest a real frame 2026-01-11 13:41:12 -06:00

Cameron Gutman 09f8e7117b Fix incorrect src pixel offset in overlay composition 
Currently harmless because no overlay has a non-zero X coordinate.
 2026-01-11 01:40:32 -06:00
Cameron Gutman 88719cc8bf Use FB_DAMAGE_CLIPS instead of drmModeDirtyFB() 2026-01-11 01:15:28 -06:00
Cameron Gutman 3ea62c0800 Call drmModeDirtyFB() for the modified composition regions 2026-01-10 23:53:07 -06:00
Cameron Gutman 7643cc929e Implement DRM overlay composition 
This allows overlays to work on drivers that only have one usable
overlay plane and when we are using the primary plane (which often
must be exactly CRTC-sized) to overlay on top of a video underlay.

Cameron Gutman 377409f313 Fix oversized DRM dumb buffer for 4:2:0 uploads 2026-01-06 00:49:49 -06:00
Cameron Gutman 80ddd5ba13 Fix software upload for DRM renderer with non-720p resolutions 
The buffer allocated for the 720p test frame was left around
and we would attempt to reuse it even if the stream had frames
of a different size.
 2026-01-06 00:35:36 -06:00
Cameron Gutman 4a547eb05e Add fourcc_mod_is_vendor() definition for older headers 2026-01-05 23:00:31 -06:00
Cameron Gutman 1c6ed8f390 Remove atomic test-only commit 
This is currently race-prone because nothing is synchronizing
between other Qt and SDL uses of DRM master, so it can cause
false negatives if we can't retake master ourselves.

Cameron Gutman e6f41f5574 Improve DRM renderer plane compatibility testing 
For atomic drivers, use a test-only commit to fully exercise the
path that we will be using when rendering.

For legacy drivers, mask the variable portion of Broadcom modifiers
before matching with IN_FORMATS.

Cameron Gutman bd32370b6d Fix libdrm return value vs errno confusion 
libdrm is inconsistent between returning -1 with an errno set
and just returning -errno as the return value. Figuring out which
behavior a given libdrm function has require reading the source :/
 2026-01-04 21:50:40 -06:00
Cameron Gutman 8726c1c7d0 Bring back atomic async page flip support 
Now that we're referencing the AVFrame to keep the buffers from
being reused during scanout, this should hopefully work better.
 2026-01-04 19:34:13 -06:00
Cameron Gutman 34881599f5 Reference the AVFrame while the backing DMA-BUFs are used for scanout 
This prevents tearing and other artifacts caused by the decoder
writing to a DMA-BUF that is currently being displayed.

Cameron Gutman b8c3658c42 Skip modifier check if the frame doesn't have any modifiers 2026-01-03 02:53:44 -06:00
Cameron Gutman d3fb52c5a0 Check modifiers support in IN_FORMATS property 
As it turns out, there *are* in fact hardware vendors dumb enough
to ship V4L2 decoders that output buffers which are unsupported by
any plane on their display hardware. By checking modifiers, we can
still fall back to GLES on GL_IS_SLOW=1 builds in this case.

Cameron Gutman 2972022ced Remove async and non-blocking page flip support 
It doesn't work well in practice for a few major reasons:
- It can result in the decoder writing on DMA-BUFs being used by the display
- It can generate page flip events that collide with Qt/SDL
- It can stall the decoder if the DMA-BUF has a fence on it from the display driver
 2026-01-03 00:41:14 -06:00

Cameron Gutman be460970a8 Remove use of DMA_BUF_IOCTL_SYNC 
It's only necessary on "real" DMA-BUFs, not dumb buffers.

Cameron Gutman d50ba06321 Implement DRM atomic renderer with overlay support 
Fixes #1733
 2026-01-02 01:24:35 -06:00
Cameron Gutman b108684edc Handle missing bitstream restrictions element in H.264 SPS fixup 
NVENC on the 591.59 driver seems to not include the bitstream
restrictions element, which renders our attempt to set the
max_dec_frame_buffering value ineffective. Handle this by
providing inserting default bitstream restrictions if one
is not present.

Cameron Gutman b6d10a34c8 Update blocking swap buffer opt-out comment 2025-12-30 15:43:31 -06:00
Cameron Gutman 232ff0b3c6 Revert "Remove opt-out of blocking swap buffers logic for KMSDRM" 
This significantly hurts performance on slower GPUs by preventing
the pipelining required when frametimes exceed the video frame
interval.

This reverts commit c26e437f40.
 2025-12-30 15:39:47 -06:00

Cameron Gutman ceef792f04 Use display scaling to improve performance on slow GPUs 
This dramatically improves performance for lower resolution
streams on slow GPUs when using the GL and Vulkan renderers.

Cameron Gutman 3e5aa9b127 Simplify EGLImageFactory and remove caching logic for now 
The platforms that would most benefit (embedded V4L2 decoders)
either don't use frame pooling or don't synchronize with
modified DMA-BUFs unless eglCreateImage() is called each time.

Cameron Gutman f1451a0db3 Fix UB due to missing shader attribute location binding 
Mesa drivers seem to generally bind attributes in order, but the
proprietary PowerVR driver (pvr) doesn't and renders incorrectly
as a result.
 2025-12-27 23:56:17 -06:00
Cameron Gutman 8a5f34fb01 Remove logic to force the OpenGL ES library to load 
This isn't necessary now that we turn on EGL everywhere,
and it breaks OpenGL ES 2.0 support too.
 2025-12-27 23:11:53 -06:00
Cameron Gutman d1f43ca258 Use ESSL 1.0 for EGLRenderer shaders 
We still ostensibly support GLES 2.0 GPUs.
