This MR improves quartz video seeking particularly for MPEG-1 video. The quartz decoder now flushes the wg_transform buffers on seek. Furthermore, the GStreamer plugin, avdec_mpeg2video, now receives additional information equivalent to an MPEG-1 sequence header, allowing seeking even when such headers are not regularly present. If you're looking for a test video, I recommend the Kirby video available at [1]. It contains only a single sequence header, which makes it suitable for testing.
