Matroska makes it pretty hard to resync correctly on broken files: random data returns "valid" EBML IDs with a high probability, and when trying to skip them it's likely that you skip a random amount of data (instead of considering the element length invalid). Improve upon this by skipping known level 1 elements only. Consider everything else invalid and call the resync code. This might result in annoying behavior when Matroska adds new level 1 elements, although it won't be particularly harmful. Matroska doesn't really allow us to do better (even mkvtoolnix explicitly checks for known level 1 elements). Since we now don't always want to combine EBML element skipping and resyncing, remove ebml_read_skip_or_resync_cluster(), and make ebml_read_skip() more tolerant against skipping broken elements. Also, don't resync when reading sub-elements, and instead do resyncing when reading them results in an error. |
