It also tidies things up a bit. Some more decode logging. 2016-11-20T23:58:51Z Carl Hetherington cth@carlh.net 2016-11-20T23:58:51Z urn:sha1:878e19aabf2278828a3c9b518e0804b2cef0c01e Move position variables into the video/audio/subtitle decoder classes. 2016-11-19T20:40:36Z Carl Hetherington cth@carlh.net 2016-11-19T20:40:36Z urn:sha1:f113b2aaca7a65f7b37e12a7d9f3f99e2d834e81 Cope with offsets between video/audio/subtitle data in a muxed file. 2016-11-19T00:51:05Z Carl Hetherington cth@carlh.net 2016-11-19T00:31:37Z urn:sha1:24e890682b3f2aa211277ad8b6b3591f2026d4be A possibly-better approach to seeking. 2016-11-17T01:06:31Z Carl Hetherington cth@carlh.net 2016-10-07T15:22:38Z urn:sha1:97d39f46795af78b84d5f7bc9118a188f2864781 Before this commit, decoders try to guess whether they should request a seek based on what they have in their buffers. This seems reasonable for video and audio, which will always (I think) have some data lying around to give an indication of where their parent decoders are in the timeline. It doesn't work so well for subtitles, as the storage of subs is cleared out based on time (+/- 5s of "now") so there is a good chance that the storage will be empty. This gives the subtitle decoder no chance of knowing where its parent is, so it's very likely to seek. This commit asks the parent decoder to seek if it wants to, and it decides based on a knowledge of roughly where it is in the timeline. Hence the sub-decoders just see if they have got the data that is being requested, and if not they suggest to the parent that it might like to seek. They then start calling pass(). Hence the parent should only seek if some calls to pass() are not going to elicit the required data in a reasonable time.
