From 6b57a294a32874c9cdc1de0310cbf1d693b4776f Mon Sep 17 00:00:00 2001 From: Pavel Koshevoy Date: Mon, 2 Sep 2019 00:34:35 -0600 Subject: [PATCH] lavc/v4l2_m2m: don't close the file descriptor we don't own ff_v4l2_m2m_create_context initialized V4L2m2mContext.fd to 0 which is a valid file descriptor value. Next ff_v4l2_m2m_codec_init failed and v4l2_m2m_destroy_context closed file descriptor 0 even though it didn't belong to V4L2m2mContext.
