From e7d800fe89d337a0414d4d3b2de4162d94fe7046 Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Fri, 30 Jun 2023 17:14:38 -0400 Subject: [PATCH] avdevice/decklink: move queue_size to an argument for ff_decklink_packet_queue_init The existing queue initialization function would always sets it's maximum queue size to ctx->queue_size. But because we are introducing more queues we may want the sizes to differ between them. Move the specification of the queue size into an argument, which can be passed from the caller. This patch makes no functional change to the behavior. It is being made to accommodate Marton Balin's request to split out the queue size for the new VANC queue being introduced in a later patch.
