◆ get_color_format()
Convert FFmpeg pixel format (AVPixelFormat) into APV pre-defined color format.
- Returns
- APV pre-defined color format (
- See also
- oapv.h) on success, OAPV_CF_UNKNOWN on failure

◆ apv_imgb_create()
◆ get_conf()
The function returns a pointer to the object of the oapve_cdesc_t type.
oapve_cdesc_t contains all encoder parameters that should be initialized before the encoder is used.
The field values of the oapve_cdesc_t structure are populated based on:
- the corresponding field values of the AvCodecConetxt structure,
- the apv encoder specific option values,
The order of processing input data and populating the apve_cdsc structure 1) first, the fields of the AVCodecContext structure corresponding to the provided input options are processed, (i.e -pix_fmt yuv422p -s:v 1920x1080 -r 30 -profile:v 0) 2) then apve-specific options added as AVOption to the apv AVCodec implementation (i.e -preset 0)
Keep in mind that, there are options that can be set in different ways. In this case, please follow the above-mentioned order of processing. The most recent assignments overwrite the previous values.
- Parameters
-
| [in] | avctx | codec context (AVCodecContext) |
| [out] | cdsc | contains all APV encoder encoder parameters that should be initialized before the encoder is use |
- Returns
- 0 on success, negative error code on failure
