AVFrame is an abstraction for reference-counted raw multimedia data.
| enum AVFrameSideDataType |
| Enumerator | |
|---|---|
| AV_FRAME_DATA_PANSCAN |
The data is the AVPanScan struct defined in libavcodec. |
| AV_FRAME_DATA_A53_CC |
ATSC A53 Part 4 Closed Captions. A53 CC bitstream is stored as uint8_t in AVFrameSideData.data. The number of bytes of CC data is AVFrameSideData.size. |
| AV_FRAME_DATA_STEREO3D |
Stereoscopic 3d metadata. The data is the AVStereo3D struct defined in libavutil/stereo3d.h. |
| AV_FRAME_DATA_MATRIXENCODING |
The data is the AVMatrixEncoding enum defined in libavutil/channel_layout.h. |
| AV_FRAME_DATA_DOWNMIX_INFO |
Metadata relevant to a downmix procedure. The data is the AVDownmixInfo struct defined in libavutil/downmix_info.h. |
| AV_FRAME_DATA_REPLAYGAIN |
ReplayGain information in the form of the AVReplayGain struct. |
| AV_FRAME_DATA_DISPLAYMATRIX |
This side data contains a 3x3 transformation matrix describing an affine transformation that needs to be applied to the frame for correct presentation. See libavutil/display.h for a detailed description of the data. |
| AV_FRAME_DATA_AFD |
Active Format Description data consisting of a single byte as specified in ETSI TS 101 154 using AVActiveFormatDescription enum. |
| AV_FRAME_DATA_MOTION_VECTORS |
Motion vectors exported by some codecs (on demand through the export_mvs flag set in the libavcodec AVCodecContext flags2 option). The data is the AVMotionVector struct defined in libavutil/motion_vector.h. |
| AV_FRAME_DATA_SKIP_SAMPLES |
Recommmends skipping the specified number of samples. This is exported only if the "skip_manual" AVOption is set in libavcodec. This has the same format as AV_PKT_DATA_SKIP_SAMPLES. |
| AV_FRAME_DATA_AUDIO_SERVICE_TYPE |
This side data must be associated with an audio frame and corresponds to enum AVAudioServiceType defined in avcodec.h. |
| int64_t av_frame_get_best_effort_timestamp | ( | const AVFrame * | frame | ) |
Accessors for some AVFrame fields.
The position of these field in the structure is not part of the ABI, they should not be accessed directly outside libavutil.
