      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.
