AVFrame is an abstraction for reference-counted raw multimedia data.
| 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. |
| AV_FRAME_DATA_MASTERING_DISPLAY_METADATA |
Mastering display metadata associated with a video frame. The payload is an AVMasteringDisplayMetadata type and contains information about the mastering display color volume. |
| AV_FRAME_DATA_GOP_TIMECODE |
The GOP timecode in 25 bit timecode format. Data format is 64-bit integer. This is set on the first frame of a GOP that has a temporal reference of 0. |
| AV_FRAME_DATA_SPHERICAL |
The data represents the AVSphericalMapping structure defined in libavutil/spherical.h. |
| AV_FRAME_DATA_CONTENT_LIGHT_LEVEL |
Content light level (based on CTA-861.3). This payload contains data in the form of the AVContentLightMetadata struct. |
| AV_FRAME_DATA_ICC_PROFILE |
The data contains an ICC profile as an opaque octet buffer following the format described by ISO 15076-1 with an optional name defined in the metadata key entry "name". |
| AV_FRAME_DATA_QP_TABLE_PROPERTIES |
Implementation-specific description of the format of AV_FRAME_QP_TABLE_DATA. The contents of this side data are undocumented and internal; use av_frame_set_qp_table() and av_frame_get_qp_table() to access this in a meaningful way instead. |
| AV_FRAME_DATA_QP_TABLE_DATA |
Raw QP table data. Its format is described by AV_FRAME_DATA_QP_TABLE_PROPERTIES. Use av_frame_set_qp_table() and av_frame_get_qp_table() to access this instead. |
Flags for frame cropping.
| Enumerator | |
|---|---|
| AV_FRAME_CROP_UNALIGNED |
Apply the maximum possible cropping, even if it requires setting the AVFrame.data[] entries to unaligned pointers. Passing unaligned data to FFmpeg API is generally not allowed, and causes undefined behavior (such as crashes). You can pass unaligned data only to FFmpeg APIs that are explicitly documented to accept it. Use this flag only if you absolutely know what you are doing. |
Accessors for some AVFrame fields.
These used to be provided for ABI compatibility, and do not need to be used anymore.

The following fields must be set on frame before calling this function:
This function will fill AVFrame.data and AVFrame.buf arrays and, if necessary, allocate and fill AVFrame.extended_data and AVFrame.extended_buf. For planar formats, one buffer will be allocated for each plane.

Crop the given video AVFrame according to its crop_left/crop_top/crop_right/ crop_bottom fields.
If cropping is successful, the function will adjust the data pointers and the width/height fields, and set the crop fields to 0.
In all cases, the cropping boundaries will be rounded to the inherent alignment of the pixel format. In some cases, such as for opaque hwaccel formats, the left/top cropping is ignored. The crop fields are set to 0 even if the cropping was rounded or ignored.
