avformat/matroskaenc: Regression fix for invalid MKV headers
The following three commits created a regression by writing initially
invalid mkv headers:
650e17d88b63b5aca6e0a43483e89e64b0f7d2dd avformat/matroskaenc: write a

CRC32 element on Info
ee888cfbe777cd2916a3548c750e433ab8f8e6a5 avformat/matroskaenc: postpone
writing the Tracks master
Symptoms:
- You can no longer playback a file that is still processed by ffmpeg,
e.g. VLC fails playback
- You can no longer stream a file to a client while if is still being
processed
- Various diagnosing tools show header errors or incomplete headers
(e.g. ffprobe, mediainfo, mkvalidator)
Note: The symptoms do not apply to completed files or ffmpeg runs that
were interrupted with 'q'
Cause:
The mentioned commits made changes in a way that some header elements
are only partially written in
mkv_write_header, leaving the header in an invalid state. Only in
mkv_write_trailer, these elements
are finished correctly, but that does only occur at the end of the
process.
Regression:
Before these commits were applied, mkv headers have always been valid,
even before completion of ffmpeg.
This has worked reliably over many versions of ffmpeg, to it was an
obvious regression.
Bugtracker:
This issue has been recorded as #5977 which is resolved by this patch
Patch:
The patch adds a new function 'end_ebml_master_crc32_preliminary' that
preliminarily finishes the ebml
element without destroying the buffer. The buffer can be used to update
the ebml element later during
mkv_write_trailer. But most important: mkv_write_header finishes with a
valid mkv header again.

imdct15: replace the FFT with a faster PFA FFT algorithm
This commit replaces the current inefficient non-power-of-two FFT with a
much faster FFT based on the Prime Factor Algorithm.
Although it is already much faster than the old algorithm without SIMD,
the new algorithm makes use of the already very throughouly SIMD'd power
of two FFT, which improves performance even more across all platforms
which we have SIMD support for.
Most of the work was done by Peter Barfuss, who passed the code to me to
implement into the iMDCT and the current codebase. The code for a
5-point and 15-point FFT was derived from the previous implementation,
although it was optimized and simplified, which will make its future
SIMD easier. The 15-point FFT is currently using 6% of the current
overall decoder overhead.
The FFT can now easily be used as a forward transform by simply not
multiplying the 5-point FFT's imaginary component by -1 (which comes
from the fact that changing the complex exponential's angle by -1 also
changes the output by that) and by multiplying the "theta" angle of the
main exptab by -1. Hence the deliberately left multiplication by -1 at
the end.
FATE passes, and performance reports on other platforms/CPUs are
welcome.
Performance comparisons:
iMDCT, PFA:
101127 decicycles in speed, 32765 runs, 3 skips
iMDCT, Old:
211022 decicycles in speed, 32768 runs, 0 skips
Standalone FFT, 300000 transforms of size 960:
PFA Old FFT kiss_fft libfftw3f
3.659695s, 15.726912s, 13.300789s, 1.182222s
Being only 3x slower than libfftw3f is a big achievement by itself.
There appears to be something capping the performance in the iMDCT side
of things, possibly during the pre-stage reindexing. However, it is
certainly fast enough for now.

Prep work for the next commit, which will add a new FFT algorithm
which makes the iMDCT over 3x faster than it is currently (standalone,
the FFT is with some framesizes over 10x faster).
The new FFT algorithm uses the already thouroughly SIMD'd power of two
FFT which already has SIMD for AArch64, so users of that platform will
still see an improvement.
The previous FFT+SIMD was barely 2.5x faster than the C versions on these
platforms.

avformat/hlsenc: strftime identifiers and segment index
in filenames
Putting date/time values into segment filenames is very usefull.
But to produce non-conflicting segment filenames with -use_localtime
option with date/time
values in hls_segment_filename option, sometimes is not enough.
Like in cases when multiple segments produced in the same second.
But hlsenc currently does not make possible to use segment index (%d) at
the
same time whe use_localtime is in effect, due to identifier conflict.
This patch makes possible to use strftime identifiers and still put
segment index (%d) at same time in segment filenames by introducing
second_level_segment_index flag. When -use_localtime is active,
identifier %d is for month day index, so %%d is the segment index
placeholder. This enhanced behaviour only exists when new
second_level_segment_index flag is specified.
For instance putting 'segment_%Y%m%d%H%M%S_%%05d.ts' value into
-hls_segment_filename option and specifing -hls_flags
second_level_segment_index and -use_localtime 1, may produce segment
filename as 'segment_20161230235758_00002.ts'
An example:
ffmpeg -loglevel info -y -f lavfi -i color=c=red:size=640x480:r=25 -f
lavfi -i anullsrc=r=44100:cl=stereo -c:v mpeg2video -g 25 -acodec aac
-cutoff 20000 -ac 2 -ar 44100 -ab 192k -f hls -hls_time 3 -hls_list_size
5 -hls_flags delete_segments+second_level_segment_index -use_localtime 1
-hls_segment_filename "segment_%Y%m%d%H%M%S_%%05d.ts" stream.m3u8
will produce segments filenames:
....
segment_20161227005902_00013.ts

segment_20161227005902_00015.ts
