 /* TODO: 
  *   - Handle CDCI essence
  *   - Handle more formats with RGBA descriptor (4:4:4 / 4:4:4:4 YUV, RGB656, ...)
- *   - Correctly transform for the GStreamer strides
  *   - Handle all the dimensions and other properties in the picture
  *     essence descriptors correctly according to S377M Annex E
  *   - Handle interlaced correctly, i.e. weave until we support one-field-per-buffer
