It will not be set unless the muxing codec context is also the encoding
context, which is discouraged. When the frame size is not known from
av_get_audio_frame_duration(), the fallback should still be good enough.
It will not be set if the stream codec context is not the encoding
context. Use av_get_audio_frame_duration() instead, it should work for
all audio codecs supported by the muxer.
Having a configure option with the same name as a MIPS ISA is confusing,
so better to remove it. This option was being used to add some
optimizations to a specific core (i6400). We will add the optimizations
just when the i6400 core has been detected, in a later patch.

Relying on AVPixFmtDescriptor.nb_components is cleaner and faster than
checking data and linesize for every possible plane.

The transpose_4x4H is wrong which cost me much time to find this bug. The orders of r2 and r3 are wrong,
this bug waste me much time while I make aarch64 arm instruction which used the function.
This also removes a #ifdef and special case for the fixed point case

-hex and -dump command line options do nothing unless -loglevel debug is set.
-dump by itself is useful for monitoring live streams (to get the current PTS for example) however when it is used with -loglevel debug for an RTMP stream, librtmp also dumps the packet data which makes the output too noisy.
do_pkt_dump is only set in check_keyboard_interaction or by the -dump command line option so this change should have no effect on any other parts of the code..

If the input contains too many too large values, the imdct can overflow.
Even if it didn't, the output would be larger than the valid range of 29
bits.
Note that this is a very delicate limit: Allowing values up to 1<<25
does not prevent input larger than 1<<29 from arriving at
sbr_sum_square, while limiting values to 1<<23 breaks the
fate-aac-fixed-al_sbr_hq_cm_48_5.1 test.
