[FFmpeg-devel] [PATCH] libavcodec/videotoolboxenc: fix pixel buffer memory leak

[YuTong Song]

From: songyutong <songyutong at kuaishou.com>

In function vtenc_populate_extradata(), there is a manually created
pixel buffer that has not been released. So we should use CVPixelBufferRelease
to release this pixel buffer at the end, otherwise will cause a memory leak.
