[FFmpeg-devel] [PATCH 6/8] avformat/matroskadec: Use right number of tracks

When demuxing a Matroska/WebM file, streams are added for tracks and for attachments, so that the array containing the former can be NULL even when the corresponding AVFormatContext has streams. So check for there to be tracks in the MatroskaDemuxContext instead of just streams in the AVFormatConte

[FFmpeg-devel] [PATCH 3/8] avformat/matroskadec: Fix handling gigantic durations

matroska_parse_block currently asserts that the duration is not equal to AV_NOPTS_VALUE, but there is nothing that actually guarantees this. It is easy to create (spec-compliant) files which run into this assert; so replace it and instead cap the duration to INT64_MAX, as the duration field of an A

[FFmpeg-devel] [PATCH 7/8] avformat/matroskadec: Use already parsed cues if available

1. The Matroska CuePoints (the index entries) contain timestamps and offsets as uint64_t. When adding them to a stream's index, they will be automatically converted to int64_t. Up until now, there was no check for whether a overflow happened during said conversion. This has been changed. Given that

This function can fail just like the seeks that it replaced; and just like the seeks that it replaced, it was left unchecke

[FFmpeg-devel] [PATCH 4/8] avformat/matroskadec: Sanitize seekhead entries

A Seek element in a Matroska SeekHead should contain a SeekID and a SeekPosition element and upon reading, they should be sanitized: Given that IDs are restricted to 32 bit, longer SeekIDs should be treated as invalid. Instead currently the lower 32 bits have been used. For SeekPosition, no check
