* frei0r: handle string paramsRaphael Graf2018-08-30
| | | | | | | | | This is needed for some of the frei0r filters (facebl0r and facedetect) which accept string parameters. Fixes the issue described here: http://www.ffmpeg-archive.org/Unable-to-set-ffmpeg-frei0r-facedetect-filter-parameter-td4680190.html Signed-off-by: Raphael Graf <r@undefined.ch>

* ffmpeg: add correct field for raw pts in -progress reportGyan Doshi2018-08-28
| | | | | | | | | PTS is in microseconds, so correct field name is out_time_us. Old field out_time_ms kept for now - will be removed after a suitable transition period. Fixes #7345
* atrac9dec: clean up code slightlyRostislav Pehlivanov2018-08-28
| | | | | | | Just remove some dead variable assignments, unneeded variables and change the FFMAX order to something more readable. Still identical. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* atrac9dec: implement LFE channel decodingRostislav Pehlivanov2018-08-27
| | | | | | | Much simpler than regular decoding, does allow for 5.1 and 7.1 streams to be decoded without desync. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* atrac9dec: relax gradient value requirementsRostislav Pehlivanov2018-08-27
| | | | | | | | Unlike the range, the gradient start value does not have to be lower than the end value. Does allow more files to be correctly decoded without errors. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* configure: speed up check_deps()Avi Halachmi (:avih)2018-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | x4 - x25 faster. check_deps() recursively enables/disables components, and its loop is iterated nearly 6000 times. It's particularly slow in bash - currently consuming more than 50% of configure runtime, and about 20% with other shells. This commit applies few local optimizations, most effective first: - Use $1 $2 ... instead of pushvar/popvar, and same at enable_deep* - Abort early in one notable case - empty deps, to avoid costly no-op. - Smaller changes which do add up: - Handle ${cfg}_checking locally instead of via enable[d]/disable - ${cfg}_checking: test done before inprogress - x2 faster in 50%+ - one eval instead of several at the empty-deps early abort path. - The "actual work" part is unmodified - just its surroundings. Biggest speedups (relative and absolute) are observed with bash. Tested-by: Michael Niedermayer <michael@niedermayer.cc> Tested-by: Helmut K. C.

* configure: speed up print_enabled_components()Avi Halachmi (:avih)2018-08-27
| | | | | | | | | | | | | | | | | | | | | | x4 - x10 faster. Inside print_enabled components, the filter_list case invokes sed about 350 times to parse the same source file and extract different info for each arg. This is never instant, and on systems where fork is slow (notably MSYS2/Cygwin on windows) it takes many seconds. Change it to use sed once on the source file and set env vars with the parse results, then use these results inside the loop. Additionally, the cases of indev_list and outdev_list are very infrequent, but nevertheless they're faster, and arguably cleaner, with shell parameter substitutions than with command substitutions.

* configure: speed up flatten_extralibs_wrapper()Avi Halachmi (:avih)2018-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x50 - x200 faster. Currently configure spends 50-70% of its runtime inside a single function: flatten_extralibs[_wrapper] - which does string processing. During its run, nearly 20K command substitutions (subshells) are used, including its callees unique() and resolve(), which is the reason for its lengthy run. This commit avoids all subshells during its execution, speeding it up by about two orders of magnitude, and reducing the overall configure runtime by 50-70% . resolve() is rewritten to avoid subshells, and in unique() and flatten_extralibs() we "inline" the filter[_out] functionality. Note that logically, "unique" functionality has more than one possible output (depending on which of the recurring items is kept). As it turns out, other parts expect the last recurring item to be kept (which was the original behavior of uniqie()). This patch preservs its output order.

* lavc/encode: fix frame_number double-countedZhong Li2018-08-27
| | | | | | | | | | Encoder frame_number may be double-counted if some frames are cached and then flushed. Take qsv encoder (some frames are cached firsty for asynchronism) as example, ./ffmpeg -loglevel verbose -hwaccel qsv -c:v h264_qsv -i in.mp4 -vframes 100 -c:v h264_qsv out.mp4 frame_number passed to encoder is double-counted and larger than the accurate value. Libx264 encoding with B frames can also reproduce it. Signed-off-by: Zhong Li <zhong.li@intel.com>

* avformat/movenc: implicitly enable negative CTS offsets for ismvJan Ekström2018-08-24
| | | | | | | | | | | ISMV lacks any sort of edit list support, as well as tfxd is effectively the PTS of the fragment for most intents and purposes. Thus, if b-frames are requested without negative CTS offsets you end up with N frames' worth of delay (tfxd PTS plus the CTS offset of the first sample). Negative CTS offsets enable the first sample to have CTS=DTS, and thus a/v desync due to b-frame reorder delay is avoided.
