[FFmpeg-devel] [PATCH 2/2] avcodec/decode: sync side_data_pref_mask across worker threads

[James Almer]

side_data_pref_mask is set during ff_decode_preinit() and then never copied to
worker threads. As such, any decoder calling one of the side data helpers that
rely on side_data_pref() in frame threaded scenarios will ignore the user set
list of side data types.
