There were frame-sync errors from FFmpeg around the crash. Subtitle "to" times used to be stored against their "from" times. 2016-02-01T00:26:37Z Carl Hetherington cth@carlh.net 2016-02-01T00:26:37Z urn:sha1:22873931f874a87fcf6a0077eddbec0f97eb3423 Sadly an example shows that from times are not unique. This patch uses a hash of stuff from the first AVSubtitle as the key. Split FilterGraph into that and VideoFilterGraph. 2015-11-18T20:51:16Z Carl Hetherington cth@carlh.net 2015-11-09T23:11:54Z urn:sha1:b147c77c6d44399ad522298ac52a481fe5988287 Speculative fix for image corruption following 2e62b2c0de47fc8e5bcb5466b2876f9b23d2ae84 2015-10-26T13:03:14Z Carl Hetherington cth@carlh.net 2015-10-26T13:03:14Z urn:sha1:a9f8daff61e227f046f5b87830ce902fd9c3fed7 Reinstate subtitle speed-up patch 526fd6de4c80a7ac9614a1cb0209efff7b171cd5 but only for preview. 2015-10-26T09:37:29Z Carl Hetherington cth@carlh.net 2015-10-26T09:37:29Z urn:sha1:2e62b2c0de47fc8e5bcb5466b2876f9b23d2ae84 Revert "Avoid decoding other packets when looking for subs." 2015-10-23T15:12:14Z Carl Hetherington cth@carlh.net 2015-10-23T15:12:14Z urn:sha1:526fd6de4c80a7ac9614a1cb0209efff7b171cd5 This reverts commit 9e025d3f85f9d6d855b3d5e6c90bca0eac3a3d49. It causes corruption in prophet_clip.xml for reasons that are not yet known. Avoid decoding other packets when looking for subs. 2015-10-16T13:38:44Z Carl Hetherington cth@carlh.net 2015-10-16T13:38:44Z urn:sha1:9e025d3f85f9d6d855b3d5e6c90bca0eac3a3d49 The "accumulation" of, for example, video data when we are looking for audio data is an *optimisation* to reduce the number of seeks. It should not be necessary for correctness (the output should be right even if we never kept anything except what we were looking for). Doing this accumulation is not always an optimisation; sometimes not doing it is better. Avoiding it when going back for subtitles is one of these cases.
