unixfdsink

Send file-descriptor backed buffers (e.g. memfd, dmabuf) over unix socket to matching unixfdsrc. There can be any number of clients, if none are connected buffers are dropped.

Buffers can have any number of GstMemory, but it is an error if any one of them lacks a file-descriptor.

GstShmAllocator is added into the allocation proposition, which makes most sources write their data into shared memory automatically.

Example launch lines

 gst-launch-1.0 -v videotestsrc ! unixfdsink socket-path=/tmp/blah
 gst-launch-1.0 -v unixfdsrc socket-path=/tmp/blah ! autovideosink
