--- Comment #11 from Tim-Philipp Müller <t.i.m at zen.co.uk> ---
Still an issue in master (1.5.90).

MKV with PGS subs (probably from Blu-Ray): Video is 720p, pgs subs are
1920x1080 video. Almost all of the subs are invisible because they fall outside
of the video window, example:

  Begin PRESENTATION_SEGMENT (0x16) packet len 19
  Video width 1920 height 1080 fps code 32  
  Win ID 0 x 686 y 888 w 542 h 117

Implementing GstVideoOverlayComposition support as in bug #685282 is probably
going to help with this, we can then use it to resize the video and use the
video overlay composition blending path (if we blit and not downstream).
