2017-09-02build: drop unused sndio_h and asoundlib_hClément Bœsch
2017-09-02build: make sndio part of the autodetected librariesClément Bœsch
sndio is already autodetected, this commit makes sure --disable-autodetect actually disable it unless --enable-sndio is specified.
2017-09-02build: make jack part of the autodetected librariesClément Bœsch
jack is already autodetected, this commit makes sure --disable-autodetect actually disable it unless --enable-jack is specified.
2017-09-02build: make alsa part of the autodetected librariesClément Bœsch
alsa libs are already autodetected, this commit makes sure --disable-autodetect actually disable it unless --enable-alsa is specified.
2017-09-02build: make sure a disabled autodetect still pick the libc's iconvClément Bœsch
2017-09-02build: add --disable-autodetect switchClément Bœsch
2017-09-02build: simplify weak-enabling of autodetected librariesClément Bœsch
2017-09-02build: remove vda_framework from enable_weakClément Bœsch
vda_framework is already pulled by the weakly enabled vda and videotoolbox.
2017-09-02build: replace use of HAVE_SDL2 with existing CONFIG_SDL2Clément Bœsch
There is no need for duplication.
2017-09-02build: treat sdl2 like other autodetected librariesClément Bœsch
2017-09-02build: isolate sdl-to-sdl2 aliasingClément Bœsch
This simplifies incoming SDL related changes by removing potential mismatching states of sdl and sdl2 variables. Since a component can have all kind of states (such as unset, enabled, disabled or requested), keeping these variables in sync manually in random places is not robust.
2017-09-02build: treat securetransport and schannel like other autodetected librariesClément Bœsch

2017-09-02build: treat iconv like other autodetected librariesClément Bœsch
2017-09-02build: treat crystalhd like other hwaccelsClément Bœsch
2017-09-02build: group z libs with other autodetected librariesClément Bœsch
2017-09-02avcodec/nvenc: always output picture timing SEITimo Rothenpieler
Interlaced encoding profits from it, or might even need it in some players. No harm in enabling it unconditionally. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>
2017-09-01avcodec/internal: move FF_QSCALE_TYPE defines from avcodec.hJames Almer
Their use in the public header is deprecated and will be removed, but they are still needed by some codecs at least as long as qscale related deprecated fields in the AVFrame struct remain in the tree.

It's already defined and actually enabled depending on compiler options elsewhere. Signed-off-by: James Almer <jamrial@gmail.com>
2017-09-01lavf: make avio_read_partial() publicwm4
Main use-case is proxying avio through a foreign I/O layer and a custom AVIO context, without losing latency and performance characteristics. Signed-off-by: Luca Barbato <lu_zero@gentoo.org> Merged from Libav commit 173b56218f39c64.
2017-09-01avformat/avio: update avio_alloc_context() doxyJames Almer

2017-09-01avio: add a destructor for AVIOContextAnton Khirnov
Before this commit, AVIOContext is to be freed with a plain av_free(), which prevents us from adding any deeper structure to it. (cherry picked from commit 99684f3ae752fc8bfb44a2dd1482f8d7a3d8536d) Signed-off-by: James Almer <jamrial@gmail.com>

2017-09-01avformat/mov: prevent duplication of first fragment's ctts_dataDaniel Glöckner
MP4 files with fragments might have the first moof box that is mentioned in a fragment index before the first mdat box. Since it is then already parsed by mov_read_header, we have to make sure that mov_switch_root will not parse it again when seeking by setting the headers_read flag in the index. Parsing it a second time would cause the ctts_data array to receive a second copy of the information from the trun box, leading to wrong PTS values for the second and following fragments in presence of B-frames. Fixes ticket 6560. Signed-off-by: Daniel Glöckner <daniel-gl@gmx.net> Reviewed-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2017-09-01avformat/mov: Bail when invalid sample data is present.Dale Curtis
ctts data in ffmpeg relies on the index entries array to be 1:1 with samples... yet sc->sample_count can be read directly from the 'stsz' box and index entries are only generated if a chunk count has been read from 'stco' box. Ensure that if sc->sample_count > 0, sc->chunk_count is too as a basic sanity check. Additionally we need to check that after the index is built we have the right number of entries, so we also check in mov_read_trun() that sc->sample_count == st->nb_index_entries.

2017-08-31avformat/concatdec: add fallback for calculating file durationJustin Ruggles
If a file does not have a known duration, this leads to the timestamps starting over for the next file, causing non-monotonic timestamps. To prevent this, track the duration during demuxing and use it to determine the current file duration before opening the next file. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
