* avformat/allformats: Making av_register_all() thread-safe.Vivekanand2016-08-131-1/+2
| | | | | | | | | | | | | | | When multiple threads tries to call av_register_all(), the first thread sets initialized to 1 and do the register process. At the same time, other thread might also call av_register_all(), which returns immediately because initialized is set to 1 (even when it has not completed registering codecs). We can avoid this problem if we set initialised to 1 while exiting from function.

| | | | | | | | | | | | | This reverts commit cb8646af24bd8e9627cc5e1c62b049a00fe0b07b. This change has brough more issues than benefits, between compilation time failures depending on flags used and code miscompilation causing runtime crashes. See the "[PATCH 2/2] configure: Enable GCC vectorization on ≥4.9" thread in the ffmpeg-devel mailing list for the relevant discussion.

This is problematic if the later packets are not the same codec type (e.g. private allocated during Vorbis parsing, but later packets are Opus and the private is assumed to be the oggopus_private type in opus_header()).
