Yunfei Dong (董云飞) June 26, 2023, 3:53 a.m. UTC
  The shared struct 'mtk_vcodec_ctx/dev' will be changed to 'mtk_vcodec_enc_ctx/dev'
and 'mtk_vcodec_dec_ctx/dev' in order to separate encoder and decoder. Removing
common struct 'mtk_vcodec_ctx/dev' for shared interface which encoder and decoder
used at the same time. Then encoder and decoder can call the same interface
independently.
