The video is 650x850, and while `MFCalculateImageSize()` returns `828750`, `gst_video_info_from_caps()` fills `src_video_info` in `wg_transform_read_data()` with a size of `831300`. The caps object has no paddings, but the gstreamer source has in `video-info.c` for NV12:
```
      info->stride[0] = GST_ROUND_UP_4 (width);
```
