[FFmpeg-devel] [PATCH] avutil/hwcontext_vulkan: Fix memleaks when transfer to vulkan

[Zhao Zhili]

From: Zhao Zhili <zhilizhao at tencent.com>

Without ff_vk_exec_discard_deps which is called by ff_vk_exec_wait,
the reference count of hwframe context cannot reach zero due to
circular reference created by ff_vk_exec_add_dep_frame.

Fix #10873
