Originally added as a private entry in  commit 3f75e5116b900f1428aa13041fc7d6301bf1988a, its grouping with  the comment noting its private state was missed during merging of the field  from Libav (most likely due to an already existing field in between). 2021-09-21 - 0760d9153c3 - lavu 57.7.100 - pixfmt.h  Add AV_PIX_FMT_X2BGR10. 2021-09-20 - 8d5de914d31 - lavu 57.6.100 - mem.h  Deprecate av_mallocz_array() as it is identical to av_calloc(). 2021-09-20 - 176b8d785bf - lavc 59.9.100 - avcodec.h  Deprecate AVCodecContext.sub_text_format and the corresponding  AVOptions.
