These are some utility functions, which use a DSP context but operate on higher level structures like video frames. As usual, these are supported for any format.
| int gavl_dsp_interpolate_video_frame | ( | gavl_dsp_context_t * | ctx, | |
| gavl_video_format_t * | format, | |||
| gavl_video_frame_t * | src_1, | |||
| gavl_video_frame_t * | src_2, | |||
| gavl_video_frame_t * | dst, | |||
| float | factor | |||
| ) |
Do a linear interpolation of a video frame.
| ctx | A DSP context | |
| format | Video format | |
| src_1 | Frame 1 | |
| src_2 | Frame 2 | |
| dst | Destination frame | |
| factor | Interpolation factor |
If the quality is at least GAVL_QUALITY_MIN, this function never fails.

| gavl_audio_frame_t * | frame, | |||
| const gavl_audio_format_t * | format | |||
| ) |
Swap endianess an audio frame.
| ctx | An initialized dsp context | |
| frame | An audio frame | |
| format | The format of the frame |
| int gavl_dsp_video_frame_swap_endian | ( | gavl_dsp_context_t * | ctx, | |

| const gavl_video_format_t * | format | |||
| ) |
Swap endianess a video frame.
| ctx | An initialized dsp context | |
| frame | A video frame | |
| format | The format of the frame |
If the quality is at least GAVL_QUALITY_MIN, this function never fails.
