Due to the recent change of using FFmpeg to decode MJPEG, MJPEG was
getting included in the delayed device check. This fixes that so that
it doesn't. MJPEG can decode in real time.
IsEncoded is meant to be used to indicated delayed devices, such as
older Elgato devices, or Hauppauge device. Devices that use H264 and
have a 800+ millisecond latency. This changes the function name to
better indicate that.
Add a separate shader for area upscaling to take advantage of bilinear
filtering. Iterating over texels is unnecessary in the upscale case
because a target pixel can only overlap 1 or 2 texels in X and Y
directions. When only overlapping one texel, adjust UVs to sample texel
center to avoid filtering.
Also add "base_dimension" uniform to avoid unnecessary division.
Intel HD Graphics 530, 644x478 -> 1323x1080: ~836 us -> ~232 us
Enable B-Pyramid frames to improve quality for high motion content.
B-pyramid allows a B-frame to choose closer frames for reference which
may have higher correlation.
Adjusts packet priority to avoid dropping referable B-frames
A check has been added to ensure feature is enabled only on platforms
with MSDK API 1.8 or higher - addresses crashing issues.
Move xlock after initial window listing
- XErrorLock uses static fields so when you use them recursively
they collide and do weird things. This keeps the two xlocks from
colliding.
Build obs textures based on returned pixmap texture types to ensure
compatibility during copies. (prevents glCopyImageSubData failed due to
texture incompatibilities)
Fix alpha check by using pixmap depth instead of checking channel sizes
(wrong on nvidia and maybe amd hardware)
Fix X error checking, now you will get 1 BadAlloc when pixmap allocation
fails instead "glCopyImageSubData failed" every frame. (occurs on Gnome
under special circumstances)
If a device produces video and audio timestamps atdifferent rates,
this divergence can cause massive buffering on the audio side, leading
to a capped audio buffer, and total sound loss. This change allows a
hardcoded list of devices to use the existing decoupling logic. For
now, only "GV-USB2" has been added.
When combined with another fix, 5+ hours of stable audio without any
buffering on my GV-USB2 where it used to drop sound completely after
an hour or so.
