avci

AVCodecInternal DecodeContext::avci

Definition at line 64 of file decode.c.

intra_only_flag

int DecodeContext::intra_only_flag

This is set to AV_FRAME_FLAG_KEY for decoders of intra-only formats (those whose codec descriptor has AV_CODEC_PROP_INTRA_ONLY set) to set the flag generically.

Definition at line 71 of file decode.c.

Referenced by decode_simple_internal(), ff_decode_internal_sync(), ff_decode_preinit(), and ff_decode_receive_frame_internal().

initial_pict_type

enum AVPictureType DecodeContext::initial_pict_type

This is set to AV_PICTURE_TYPE_I for intra only video decoders and to AV_PICTURE_TYPE_NONE for other decoders.

It is used to set the AVFrame's pict_type before the decoder receives it.
