-------------------------------------+-------------------------------------
 After the threading changes to the ffmpeg CLI the {{{-thread_queue_size}}}
 input parameter is no longer respected, because the demuxed packets are no
 longer queued on the output side of the demuxers, only on the input side
 of the decoders. The queue size on the input of the decoders are not
 adjustable at the moment.

 The documentation should be updated to reflect the changes,
 -thread_queue_size as an input option should be deprecated and eventually
 removed, maybe a new per-stream decoder parameter should be added to
 provide some level of replacement for the demuxed queue_size adjustment
 functionality.
