a162fa0772 avformat/yuv4mpegenc: Simplify writing global and packet headers
YUV4MPEG writes a string as header for both the file itself as well as
for every frame; these strings contain magic strings and these were up
until now included in the string to write via %s. Yet they are compile
time constants, so one can use the compile-time string concatentation
instead of inserting these strings at runtime.
Furthermore, the global header has been written via snprintf() to
a local buffer first before writing it. This can be simplified by using
avio_printf().

97fa669a6f avformat/mov: Only read the mfra size once during sidx parsing
On files with more than one sidx box, like live fragmented MP4
files, it was previously re-reading and seeking on every singl
sidx box, leading to extremely poor performance on larger files,
especially over the network.

Only do it on the first one, and stash its result.

d1c6e09d09 h264_redundant_pps: Make it reference-compatible
Since c6a63e1109, the parameter sets
modified as content of PPS units were references shared with the
CodedBitstreamH264Context, so modifying them alters the parsing process
of future access units which meant that frames often got discarded
because invalid values were parsed. This patch makes h264_redundant_pps
compatible with the reality of reference-counted parameter sets.

Fixes #7807.

42daac1c74 cbs: Add support functions for handling unit content references
Use the unit type table to determine what we need to do to clone the
internals of the unit content when making copies for refcounting or
writeability.  (This will still fail for units with complex content
if they do not have a defined clone function.)

Setup and naming from a patch by Andreas Rheinhardt
<andreas.rheinhardt@gmail.com>, but with the implementation changed
to use the unit type information if possible rather than requiring a
codec-specific function.

bc7a7e0d65 cbs: Describe allocate/free methods in tabular form
Unit types are split into three categories, depending on how their
content is managed:
* POD structure - these require no special treatment.
* Structure containing references to refcounted buffers - these can use
  a common free function when the offsets of all the internal references
  are known.
* More complex structures - these still require ad-hoc treatment.

For each codec we can then maintain a table of descriptors for each set of
equivalent unit types, defining the mechanism needed to allocate/free that
unit content.  This is not required to be used immediately - a new alloc
function supports this, but does not replace the old one which works without
referring to these tables.
