Types and functions for working with AVPacket. @{
Variants
AV_PKT_DATA_PALETTE
An AV_PKT_DATA_PALETTE side data packet contains exactly AVPALETTE_SIZE bytes worth of palette. This side data signals that a new palette is present.
AV_PKT_DATA_NEW_EXTRADATA
The AV_PKT_DATA_NEW_EXTRADATA is used to notify the codec or the format that the extradata buffer was changed and the receiving side should act upon it appropriately. The new extradata is embedded in the side data buffer and should be immediately used for processing the current frame or packet.
AV_PKT_DATA_PARAM_CHANGE
An AV_PKT_DATA_PARAM_CHANGE side data packet is laid out as follows: @code u32le param_flags if (param_flags & AV_SIDE_DATA_PARAM_CHANGE_CHANNEL_COUNT) s32le channel_count if (param_flags & AV_SIDE_DATA_PARAM_CHANGE_CHANNEL_LAYOUT) u64le channel_layout if (param_flags & AV_SIDE_DATA_PARAM_CHANGE_SAMPLE_RATE) s32le sample_rate if (param_flags & AV_SIDE_DATA_PARAM_CHANGE_DIMENSIONS) s32le width s32le height @endcode
AV_PKT_DATA_H263_MB_INFO
An AV_PKT_DATA_H263_MB_INFO side data packet contains a number of structures with info about macroblocks relevant to splitting the packet into smaller packets on macroblock edges (e.g. as for RFC 2190). That is, it does not necessarily contain info about all macroblocks, as long as the distance between macroblocks in the info is smaller than the target payload size. Each MB info structure is 12 bytes, and is laid out as follows: @code u32le bit offset from the start of the packet u8 current quantizer at the start of the macroblock u8 GOB number u16le macroblock address within the GOB u8 horizontal MV predictor u8 vertical MV predictor u8 horizontal MV predictor for block number 3 u8 vertical MV predictor for block number 3 @endcode
AV_PKT_DATA_REPLAYGAIN
This side data should be associated with an audio stream and contains ReplayGain information in form of the AVReplayGain struct.
AV_PKT_DATA_DISPLAYMATRIX
This side data contains a 3x3 transformation matrix describing an affine transformation that needs to be applied to the decoded video frames for correct presentation.
See libavutil/display.h for a detailed description of the data.
AV_PKT_DATA_STEREO3D
This side data should be associated with a video stream and contains Stereoscopic 3D information in form of the AVStereo3D struct.
AV_PKT_DATA_AUDIO_SERVICE_TYPE
This side data should be associated with an audio stream and corresponds to enum AVAudioServiceType.
AV_PKT_DATA_QUALITY_STATS
This side data contains quality related information from the encoder. @code u32le quality factor of the compressed frame. Allowed range is between 1 (good) and FF_LAMBDA_MAX (bad). u8 picture type u8 error count u16 reserved u64le[error count] sum of squared differences between encoder in and output @endcode
AV_PKT_DATA_FALLBACK_TRACK
This side data contains an integer value representing the stream index of a “fallback” track. A fallback track indicates an alternate track to use when the current track can not be decoded for some reason. e.g. no decoder available for codec.
AV_PKT_DATA_CPB_PROPERTIES
This side data corresponds to the AVCPBProperties struct.
AV_PKT_DATA_SKIP_SAMPLES
Recommmends skipping the specified number of samples @code u32le number of samples to skip from start of this packet u32le number of samples to skip from end of this packet u8 reason for start skip u8 reason for end skip (0=padding silence, 1=convergence) @endcode
AV_PKT_DATA_JP_DUALMONO
An AV_PKT_DATA_JP_DUALMONO side data packet indicates that the packet may contain “dual mono” audio specific to Japanese DTV and if it is true, recommends only the selected channel to be used. @code u8 selected channels (0=mail/left, 1=sub/right, 2=both) @endcode
AV_PKT_DATA_STRINGS_METADATA
A list of zero terminated key/value strings. There is no end marker for the list, so it is required to rely on the side data size to stop.
AV_PKT_DATA_SUBTITLE_POSITION
Subtitle event position @code u32le x1 u32le y1 u32le x2 u32le y2 @endcode
AV_PKT_DATA_MATROSKA_BLOCKADDITIONAL
Data found in BlockAdditional element of matroska container. There is no end marker for the data, so it is required to rely on the side data size to recognize the end. 8 byte id (as found in BlockAddId) followed by data.
AV_PKT_DATA_WEBVTT_IDENTIFIER
The optional first identifier line of a WebVTT cue.
AV_PKT_DATA_WEBVTT_SETTINGS
The optional settings (rendering instructions) that immediately follow the timestamp specifier of a WebVTT cue.
AV_PKT_DATA_METADATA_UPDATE
A list of zero terminated key/value strings. There is no end marker for the list, so it is required to rely on the side data size to stop. This side data includes updated metadata which appeared in the stream.
AV_PKT_DATA_MPEGTS_STREAM_ID
MPEGTS stream ID as uint8_t, this is required to pass the stream ID information from the demuxer to the corresponding muxer.
AV_PKT_DATA_MASTERING_DISPLAY_METADATA
Mastering display metadata (based on SMPTE-2086:2014). This metadata should be associated with a video stream and contains data in the form of the AVMasteringDisplayMetadata struct.
AV_PKT_DATA_SPHERICAL
This side data should be associated with a video stream and corresponds to the AVSphericalMapping structure.
AV_PKT_DATA_CONTENT_LIGHT_LEVEL
Content light level (based on CTA-861.3). This metadata should be associated with a video stream and contains data in the form of the AVContentLightMetadata struct.
AV_PKT_DATA_A53_CC
ATSC A53 Part 4 Closed Captions. This metadata should be associated with a video stream. A53 CC bitstream is stored as uint8_t in AVPacketSideData.data. The number of bytes of CC data is AVPacketSideData.size.
AV_PKT_DATA_ENCRYPTION_INIT_INFO
This side data is encryption initialization data. The format is not part of ABI, use av_encryption_init_info_* methods to access.
AV_PKT_DATA_ENCRYPTION_INFO
This side data contains encryption info for how to decrypt the packet. The format is not part of ABI, use av_encryption_info_* methods to access.
AV_PKT_DATA_AFD
Active Format Description data consisting of a single byte as specified in ETSI TS 101 154 using AVActiveFormatDescription enum.
AV_PKT_DATA_NB
The number of side data types. This is not part of the public API/ABI in the sense that it may change when new side data types are added. This must stay the last enum value. If its value becomes huge, some code using it needs to be updated as it assumes it to be smaller than other limits.
