Shengqi Yu	a92167ea6e	glmixer: Add GL_SYNC_META option to bufferpool ... when pipline is glvideomixerelement->glcolorconvertelement->gldownloadelement and glcolorconvertelement is not passthrough, the gl bufferpool between glvideomixerelement and glcolorconvertelement will not add gl sync meta during allocating buffer. This will cause that glcolorconvert's inbuf has no sync meta to wait for. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/6756>	2024-04-29 19:15:39 +00:00
Matthew Waters	9d867356df	gl/bufferpool: add configuration to extend buffer lifetime before reuse ... Fixes a potential GPU stall if an immediately freed texture/buffer is attempted to be reused immediately by the CPU, e.g. when uploading. Problematic scenario is this: 1. element does GPU processing reading from texture 2. frees the buffer back to the pool 3. pool acquire returns the just released buffer 4. GPU processing then has to wait for the previous GPU operation to complete causing a stall If there was a reliable way to know whether a buffer had been finished with across all GPU drivers, we would use it. However as that does not exist, this workaround is to keep the released buffer unusable until the next released buffer. This is the same approach as is used in the qml (Qt5) elements.

Matthew Waters	b291efe44b	gldownload: handle passthrough without a critical ... With passthrough mode, gldownload/glbasefilter may not ever retrieve a relevant GstGLContext as it doesn't actually query the surrounding elements. Guard against that.
