From ba96cdd551e7bf938ae8af90e14498edd09ee71a Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Thu, 26 Nov 2020 23:59:39 +0100 Subject: [PATCH] avcodec/cri: Make decoder init-threadsafe The only thing that stands in the way of adding the FF_CODEC_CAP_INIT_THREADSAFE flag to the Cintel RAW decoder is its usage of ff_codec_open2_recursive(): This function requires its caller to hold the lock for the mutex that guards initialization of AVCodecContexts whose codecs have a non-threadsafe init function and only callers whose codec does not have the FF_CODEC_CAP_INIT_THREADSAFE flag set hold said lock (the others don't need to care about said lock). But one can set the flag if one switches to avcodec_open2() at the same time.
