Combined with the blit filter the process function of the source is
often called without a valid buffer, which results in a crash. This hack
mitigates this.
If the modifier for a format is not fixated yet, we will use vulkan to
fixate a modifier, update the parsed format, change the EnumFormats mask
and exit early. This triggers a new enum_params with EnumFormats and a
new set_param for Format.
This commit add helpers to create and to import a DmaBuf via the
external_dmabuf_info struct.
The import path is based on the image creation of wlroots and the create path is
inspired by the wlroots vulkan allocator MR.
vulkan_wait_idle waits until the device is idle and all referenced
objects can be destroyed.
vulkan_wait_fence waits until a fence is triggered by a finished
queueSubmit.
vulkan: wait on fence
This commit should just shuffle code around with no functional changes.
The goal is to ease development of simple vulkan nodes by providing
generic helpers.
The default period is based on the default rate and might be too small
when using high samplerates. Scale the rate with the samplerate and make
sure it's a power of 2 to avoid trouble.
Fixes#3444
The tag param has a list of arbitrary key/value pairs. Like the Latency
param, it travels up and downstream. Mixers will append the info
dictionaries or do some more fancy merging.
The purpose is to transport arbirary metadata, out-of-band, through the
graph and it's used for stream metadata and other stream properties.
Add an xrun counter in the clock that accumulated the duration of
xruns. Fill this in in alsa-pcm.
A client could use this to dectect xruns (when it changes) and to align
the position and nsec after an xrun.
