This is a substitute for the url_fskip function that was deprecated by
commit 0300db8ad7. avio_fskip is provided to
improve demuxer code readability. It distinguishes the act of skipping over
unknown or irrelevant bytes from the standard avio_seek operation.

Should an AVC-1 in MP4 stream not contain SPS or PPS NAL units,
this BSF is then unable to allocate an output buffer for the
modified stream. Warn that the resulting stream may be unplayable.
Fix roundup issue #2386.

If this flag is set, the protocol can handle URLs where the
scheme is a nested scheme such as applehttp+file: - the protocol
can handle any URL where the first segment of the nested scheme
belongs to this protocol.

This fixes compilation with preprocessors which do not add whitespace
around replaced tokens, resulting in invalid expressions like 1--1.

Currently it is always 4, but this change will allow it to be adjusted when
bandwidth-related features are added such as channel coupling, enhanced
channel coupling, and spectral extension.
This moves setting the thread count to a minimum of 1 to
frame_thread_init(), allowing a value of zero to propagate
through to the codec if frame threading is not used. This
makes auto-threads work in libx264.

In most cases, s->buf_ptr will be equal to s->buf_end when
fill_buffer is called, but this may not always be the case, if
we're seeking forward by reading (permitted by the short seek
threshold).
If fill_buffer is writing to s->buf_ptr instead of s->buf_end (when
they aren't equal and s->buf_ptr is ahead of s->buffer), the data
between s->buf_ptr and s->buf_end is overwritten, leading to
inconsistent buffer content. This could return incorrect data if
later seeking back into the area before the current s->buf_ptr.

For intra codecs, ff_thread_finish_setup() is called before decoding starts
automatically. However, get_buffer can only be used before it's called, so
adding this requirement broke frame threading for them. Fixed by moving the
call until after get_buffer is finished.

Although not documented, clang does support the --sysroot flag, and it
does the right thing. Use this flag intead of -isysroot which only
applies to header file searches, not the linker.

The assembler emits literal pools too far from the load instructions,
so we must do it explicitly at a suitable location.

Use the FATE_SAMPLES environment variable if samples location
is not set with the --samples configure option or on the make
command line.

This causes lxlite to use stdout instead of vioXXX
functions. This improves fate and build logs readability.
