      avformat/matroskadec: Use right number of tracks · 0260352d
      Andreas Rheinhardt authored 
      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
AVFormatContext before dereferencing the pointer to the tracks.

      avformat/matroskadec: Fix handling gigantic durations · a2ab8bab
      Andreas Rheinhardt authored 
      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 AVPacket is an int64_t.

      avformat/matroskadec: Move AVBufferRef instead of copying, fix memleak · 751f2851
      Andreas Rheinhardt authored 
      EBML binary elements are already made reference-counted when read;
so when populating the AVStream.attached_pic, one does not need to
allocate a new buffer for the data; instead the current code just
creates a new reference to the underlying AVBuffer. But this can be
improved even further: Just move the already existing reference.

This also fixes a memleak that happens upon error because
matroska_read_close has not been called in this scenario.

      avformat/hlsenc: Always treat numbers as decimal · 2c738c75
      Andreas Rheinhardt authored 
      c801ab43 caused a regression: The stream
number is now parsed with strtoll without a fixed basis; as a
consequence, the "010" in a variant stream mapping like "a:010" is now
treated as an octal number (i.e. as eight, not ten). This was not
intended and may break some scripts, so this commit restores the old
behaviour.

      avcodec/hevc_mp4toannexb_bsf: Check NAL size against available input · 82d70d80
      Andreas Rheinhardt authored 
      The hevc_mp4toannexb bsf does not explicitly check whether a NAL unit
is so big that it extends beyond the end of the input packet; it does so
only implicitly by using the checked version of the bytestream2 API.
But this has downsides compared to real checks: It can lead to huge
allocations (up to 2GiB) even when the input packet is just a few bytes.
And furthermore it leads to uninitialized data being output.
So add a check to error out early if it happens.

Also check directly whether there is enough data for the length field.

      pthread_frame: change the way delay is set · 569a9d3d
      Anton Khirnov authored 
      It is a constant known at codec init, so set it in
ff_frame_thread_init(). Also, only set it for video, since the meaning
of this field is not well-defined for audio with frame threading.

Fixes availability of delay in callbacks invoked from the per-thread
contexts after 1f4cf92c.
