* avformat/hlsenc: hls_start_number_source and start_numberBodecs Bela2017-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | | start_number option starts the playlist sequence number (#EXT-X-MEDIA-SEQUENCE) from the specified number. Unless hls_flags single_file is set, it also specifies starting sequence numbers of segment and subtitle filenames. Sometimes it is usefull to have unique starting numbers at each run, but currently it is only achiveable by setting this parameter manually. This patch enables to specify start_number source parameter by introducing hls_start_number_source with 3 possible values: generic/epoch/datetime. This ensures to set start sequence number automatically for practically unique numbers. Generic option is the default and this is the curent behaviour: start_number option value specifies the start sequence number. (start_number default value is 0) If hls_start_number_source is set to epoch, then the start number will be the seconds since epoch (1970-01-01 00:00:00). If set to datetime, then the start sequence number will be based on the current date/time value as YYYYmmddHHMMSS. e.g. 20161231235659. Hls speficication allows 64 bit integers as sequence numbers. This patch also changes some code where only 32 bit integer values were handled correctly.

* avcodec: add Newtek SpeedHQ decoderSteinar H. Gunderson2017-01-11
| | | | | | | | | | | | | | This decoder can decode all existing SpeedHQ formats (SHQ0–5, 7, and 9), including correct decoding of the alpha channel. 1080p is decoded in 142 fps on one core of my i7-4600U (2.1 GHz Haswell), about evenly split between bitstream reader and IDCT. There is currently no attempt at slice or frame threading, even though the format trivially supports both. NewTek very helpfully provided a full set of SHQ samples, as well as source code for an SHQ2 encoder (not included) and assistance with understanding some details of the format.

| | | | | | | | | When allocating stack space with an alignment requirement that is larger than the current stack alignment we need to store a copy of the original stack pointer in order to be able to restore it later. If we chose to use another register for this purpose we should not pick eax/rax since it can be overwritten as a return value.

* ffserver: local OOB write with custom program nameTobias Stoeckmann2017-01-08
| | | | | | | | | | | | | | | | | | When the command line for children is created, it is assumed that my_program_name always ends with "ffserver", which doesn't have to be true if ffserver is called through a symbolic link. In such a case, it could be that not enough space for "ffmpeg" is available at the end, leading to a buffer overflow. One example would be: $ ln -s /usr/bin/ffserver ~/f; ~/f As this is only a local buffer overflow, i.e. is based on a weird program call, this has NO security impact.

* avformat/matroskaenc: Regression fix for invalid MKV headerssoftworkz2017-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following three commits created a regression by writing initially invalid mkv headers: 650e17d88b63b5aca6e0a43483e89e64b0f7d2dd avformat/matroskaenc: write a CRC32 element on Tags 3bcadf822711720ff0f8d14db71ae47cdf97e652 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 algorithmRostislav Pehlivanov2017-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* imdct15: remove the AArch64 assemblyRostislav Pehlivanov2017-01-05
| | | | | | | | | | | | | | | 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. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
