           Summary: 1 frame/page Ogg/Theora files
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.25
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

Ogg/Theora files created with gstreamer (0.10.25-2) and -base
(0.10.25-2ubuntu1) contain all theora frames/packets in separate ogg pages, 1
packet per page, thus causing high container size overhead.

For example:

  Content-Duration: 00:00:50.480
  Content-Length: 496.691 kB
  Content-Bitrate-Average: 80.604 kbps

  Theora: serialno 2065395012
      1040 packets in 1039 pages, 1.0 packets/page, 22.852% Ogg overhead

or:

  Content-Duration: 01:12:40.593
  Content-Length: 52.944 MB
  Content-Bitrate-Average: 101.850 kbps

  Theora: serialno 0012675979
      91006 packets in 91005 pages, 1.0 packets/page, 13.986% Ogg overhead

Note, that the pages and packets seem continuous, no gaps, so there shouldn't
be a reason to mux a 26 byte frame in a separate ogg page:

  |2008845077|   GP 23057207,  packetno 26: 47 bytes
  |0012675979| page 18026, granulepos 18012|2, Flags:  (1 (26))
  |0012675979|   GP 18012|2,  packetno 6: 26 bytes
  |0012675979| page 18027, granulepos 18012|3, Flags:  (1 (38))
  |0012675979|   GP 18012|3,  packetno 7: 38 bytes
  |0012675979| page 18028, granulepos 18012|4, Flags:  (1 (50))
  |0012675979|   GP 18012|4,  packetno 8: 50 bytes
  |0012675979| page 18029, granulepos 18012|5, Flags:  (1 (89))
  |0012675979|   GP 18012|5,  packetno 9: 89 bytes
  |0012675979| page 18030, granulepos 18012|6, Flags:  (1 (123))
  |0012675979|   GP 18012|6,  packetno 10: 123 bytes
  |0012675979| page 18031, granulepos 18012|7, Flags:  (1 (111))
  |0012675979|   GP 18012|7,  packetno 11: 111 bytes
