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
Let the source write into a ringbuffer when there is data available.
We then read from the ringbuffer when scheduled and use a dll to keep
the delay constant. We can later make this a driver and use the rate
correction to tweak the timeouts instead of resampling.
See #3478
Round down the size and avail to the frame size to make sure we always
send aligned frames.
When we don't have the required size, set the buffer to 0 but still send
whatever we have in the ringbuffer or else it stays there until some
unknown time when it gets flushed out again with new data.
When we don't manage to emit the notify, still mark the object as
registered. Otherwise we might not emit the unregistered
notify later on.
This usually happens when a client connects and the notifies are
suppressed for all the objects in the graph. When they later disappear
we do want to emit the unregistered notify.
