some samples to test your theora decoder

a decoder must play all these files without problems to comply with the theora specification.

320x240.ogg [0.3 MB]

  • simplest example


320x240.ogv [0.3 MB]

  • simple example with Skeleton Stream


320x240.skeleton+cmml.ogv [0.3 MB]

  • simple example with Skeleton and CMML Stream; decoders should read the Skeleton stream to identify the other streams in Ogg and ignore those that are not supported by the application


pixel_aspect_ratio.ogg [1.8 MB]

  • Aspect Ratio defined in header to 1.82/1 , it also has a theora comment header


videotestsrc-720x576-16-15.ogg [422K]

  • Aspect Ratio defined in header to 1.33/1 (PAL DVD format)


322x242_not-divisible-by-sixteen-framesize.ogg [0.3 MB]

  • both dimensions not divisible by 16 but still even - if you see a black border around the testimage you should have a look at the Spec/2.2 on page 22, to see how to use: ti.width, ti.height, ti.frame_width, ti.frame_height, ti.offset_x, ti.offset_y


[...]

  • one dimension divisible by 16 while the other one isn't


[...]

  • odd dimensions


chained_streams.ogg [2.4 MB]

  • all other samples as a chained stream. (see Spec/A.3.1 on page 157)


multi2.ogg [171 K]

  • another chained file


mobile_itu601_i_422.ogg [8 MB]

  • 4:2:2 pixel format, in the original spec and supported by the mainline decoder since alpha8 and the mainline encoder since 1.1.


ducks_take_off_444_720p25.ogg [7.2 MB]

  • Ogg Theora video 4:4:4 pixel format.


stockholm-vfr.ogg [1.8 MB]

  • Hybrid 24fps/30fps clip encoded as 120fps with dropped frames.


offset_test.ogv [0.2 MB] (10 frames, 1 fps, no visible movement, visible frame 512 x 512)


sign_irene_cif-3qi-b.ogg [1.3 MB]

  • Ogg Theora video using 3qi (adaptive quantization).

Player compliance

  • Firefox (3.6)
    • Seems to pass all tests (not sure about the 322x242 "not divisible by 16" - there is

a black line ...), but high requirements to play some (especially large) videos, behaves badly if hardware is insufficient to play in real-time

  • MPLAYER (r30369)
    • 4:2:2 and 4:4:4 do play, but look "strangely" - bad
    • Offset test fails, shows what shouldn't be visible
  • VLC
    • ...
  • DUGL Player
    • Offset test fails, shows what shouldn't be visible
