Increasing this number fix a buffer starvation problem I'm hitting with a "v4l2src ! kmssink" pipeline. kmssink requests 2 buffer as it keeps a reference on the last rendered one. So we were allocating 3 buffers for the pipeline. Once the first 2 buffers have been pushed we ended up with: - one buffer queued in v4l2 - one being pushed - one kept as last rendered If this 3rd buffer is released after that v4l2 used the first one to capture we end up with a buffer starvation problem as no buffer is currently queued in v4l2 for capture. Fixing this by adding one extra buffer to the pipeline so when one buffer is being pushed downstream the other can already be queued to capture the next frame. We were already adding 3 buffers if downstream didn't reply to the allocation query. I reduced this number to 2 to compensate the extra buffer which is now always added. https://bugzilla.gnome.org/show_bug.cgi?id=783049 |
