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, 1280x720 pixels, 25 fps, 213 frames


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).


chroma_siting_test.ogv [25K]

  • Ogg Theora video chroma siting test for 4:2:0. No motion, 1 fps, 20 seconds, 1 frame + 19 repetitions. If the player's conversion to RGB uses correct chroma subsample positioning, then the top and bottom halves should be the same color. If the top and bottom halves are different colors, then the player's chroma siting is wrong. Note that many players delegate YUV to RGB conversion to the graphics hardware or driver, which are then responsible for the chroma siting. This image shows a correct decode.

0byteframes.ogv [31k]

  • Ogg Theora video 25fps, 10 seconds long, frame only changes every second.
