In avcodec.h, the docs for AVCodecContext->framerate say:
encoding: May be used to signal the framerate of CFR content to an
encoder.
OBS is designed to always output Constant Frame Rate (CFR) content.
Instead of letting this be implied, let's explicitly set the framerate
per the docs.
When using FFmpeg-based NVENC, with b-frames, and a non-1 framerate
numerator (eg. `1001/60000` aka 59.94fps), the DTS values outputted
by FFmpeg result in invalid DTS values.
Detect when using an unpatched FFmpeg build and correct the values
accordingly.
The current method would enum though all devices looking for a matching
uid instead of directly asking for kAudioHardwarePropertyDeviceForUID.
Asking directly instead would also enable finding hidden devices that
can only be found directly via uid and not via enumerating (were we ever
to need to find such a device).
Pipewire desktop portal capture assumes premultiplied alpha, so make
sure to use the right blend equation to make translucent pixels work
correctly.
This is still broken for emissive pixels (alpha < color) since OBS seems
to unpremultiply at some point during blending, but it works properly
for translucent pixels (emissive pixel support requires an end-to-end
premultiplied pipeline).
We were calling avio_close on a field that might have held an
AVIOContext. This commit checks which type was allocated so we
can call the appropriate cleanup function.
Telling a user to "Check your driver is up to date" is too open to
interpretation, many users will use Windows Update or Device Manager to
check for updates which doesn't help. Instead, let's explicitly tell
them what is most likely to fix the problem.
- Do not set sample rate (not required here, but can be 24/32 now)
- Only set bit_rate for lossless codecs
- Only set frame_size for codecs using a fixed one
Applications that use this Vulkan extension would have image usage
mismatches because we add VK_IMAGE_USAGE_TRANSFER_SRC_BIT to
VkSwapchainCreateInfoKHR::imageUsage, so make the same modification to
VkFramebufferAttachmentImageInfo::usage.
