/**
 * video/x-dumdum is a very simple encoded video format:
 *
 * - It has I-frames, P-frames and B-frames for the purpose
 *   of testing trick modes, and is infinitely scalable, mimicking server-side
 *   trick modes that would have the server reencode when a trick mode seek with
 *   an absolute rate different from 1.0 is requested.
 *
 * - The only source capable of outputting this format, `TestSrc`, happens
 *   to always output frames following this pattern:
 *
 *   IBBBBPBBBBI
 *
 *   Its framerate is 1000 / 1, each Group of Pictures is thus 10 milliseconds
 *   long. The first frame in the stream dates back to January the first,
 *   1900, at exactly midnight. There are no gaps in the stream.
 *
 *   A nice side effect of this for testing purposes is that as the resolution
 *   of UTC (clock=) seeks is a hundredth of a second, this coincides with the
 *   alignment of our Group of Pictures, which means we don't have to worry
 *   about synchronization points.
 *
 * - Size is used to distinguish the various frame types:
 *
 *   * I frames: 20 bytes
 *   * P frames: 10 bytes
 *   * B frames: 5 bytes
 *
