Some GStreamer elements may produce buffers with very non standard strides, offsets and/or even transport each plane in different, non-contiguous pointers. This non-standard layout is communicated via GstVideoMeta structures attached to the buffers. Given this, when a GstVideoMeta is available, one should parse the layout from it instead of generating a generic one from the caps. The GstVideoFrame utility does precisely this: if the buffer contains a video meta, it uses that to fill the format and memory layout. If there is no meta available, the layout is inferred from the caps. |
