SPA_VIDEO_FLAG_VARIABLE_FPS | a variable fps is selected, fps_n and fps_d denote the maximum fps of the video
SPA_VIDEO_FLAG_PREMULTIPLIED_ALPHA | Each color has been scaled by the alpha value.
SPA_VIDEO_FLAG_MODIFIER | use the format modifier

## ◆ spa_video_interlace_mode

enum spa_video_interlace_mode

The possible values of the spa_video_interlace_mode describing the interlace mode of the stream.

Enumerator
SPA_VIDEO_INTERLACE_MODE_PROGRESSIVE | all frames are progressive
SPA_VIDEO_INTERLACE_MODE_INTERLEAVED | 2 fields are interleaved in one video frame. Extra buffer flags describe the field order.
SPA_VIDEO_INTERLACE_MODE_MIXED | frames contains both interlaced and progressive video, the buffer flags describe the frame and fields.
SPA_VIDEO_INTERLACE_MODE_FIELDS | 2 fields are stored in one buffer, use the frame ID to get access to the required field. For multiview (the 'views' property > 1) the fields of view N can be found at frame ID (N * 2) and (N * 2) + 1. Each field has only half the amount of lines as noted in the height property. This mode requires multiple spa_data to describe the fields.
