avci

AVCodecInternal DecodeContext::avci

Definition at line 62 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 69 of file decode.c.

Referenced by ff_decode_internal_sync().

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.

draining_started

int DecodeContext::draining_started

The caller has submitted a NULL packet on input.

Definition at line 86 of file decode.c.

pts_correction_num_faulty_dts

int64_t DecodeContext::pts_correction_num_faulty_dts

Number of incorrect PTS values so far.

Definition at line 87 of file decode.c.

pts_correction_last_pts

int64_t DecodeContext::pts_correction_last_pts

Number of incorrect DTS values so far.

Definition at line 88 of file decode.c.

pts_correction_last_dts

int64_t DecodeContext::pts_correction_last_dts

PTS of the last frame.

Definition at line 89 of file decode.c.

side_data_pref_mask

uint64_t DecodeContext::side_data_pref_mask

DTS of the last frame.

Bitmask indicating for which side data types we prefer user-supplied (global or attached to packets) side data over bytestream.
