The priority is higher than dav1d so it can handle hardware decoding even if
dav1d is present.
This version of lavc should only allow decoding if the decoder has a profile
that can be decoded by the hardware, otherwise it should let other decoders try
to do the decoding (dav1d, lavc with current priority, etc).
gives much better UX in gui prefs.
the range was dropped, even though ranges are enforced (mostly) unlike
value-lists within the option system, and so it can be sensible to have
them in addition to value-lists, since the avcodec module has code handling
the value of this option which maps each valid value to a specific constant
and uses a default constant for unmapped values, so keeping the range would
be pointless here.
longtext should add something of value, otherwise results in useless
tooltips and a waste of translator time.
in the ball case, feedback was that the longtext was better than the
existing shorttext.
where identical to shorttext, or near enough.
bad because:
- wastes resources.
- useless tooltips in prefs GUI (poor UX) - tooltip longtext should add
something of value.
- useless repetition of text in certain help output.
in some cases they differed only in full-stop, creating unnecessary extra
burden on translators.
The avcodec-fast option, if enabled, sets the AV_CODEC_FLAG2_FAST
option. Using AV_CODEC_FLAG2_FAST can cause use of unsafe code in
avcodec which could lead to crashes.
adapting to the new API requires more than local
patches.
The block is always passed in full, and we can
expect more than a single frame when push returns
EAGAIN.
Requires then more interpolation for timestamps before
using next input packet pts.
Should also be correct when dequeing end of stream.
Implements decoder draining
Note that the input coded buffer is now only freed if the decoding
returns a decoded frame, or the buffer has been entirely consumed
(see *pp_block = NULL).
Re-license almost all the playback modules to LGPLv2.1+ with
authorization from their respective contributors (230+)
This includes:
- access, codec, packetizers, demux
- audio filters, audio mixers, audio output
- video filters, video chroma, video output
- text renderers
- XML parser
- ARM NEON and SSE2 optimisations (mostly for chromas and filters)
Some modules are not concerned:
- BDA and DShow access modules because Manol Manolov is AWOL
- Real RTSP, because it is derived from Xine
- x264 and t140 because they are encoders only
- DLL Loader, because it is derived from MPlayer
- DTS packetizer, because Jon Lech Johansen is AWOL
- Shine and WMAfixed, because they are derived from Rockbox
- Real demuxer, as it is derived from MPlayer and Wang Bo is AWOL
- MPC demuxer, as Yavor Doganov is AWOL
- Tivo demuxer, because it is derived from an MPlayer fork
- Playlist demuxer, (WPL and ZPL parts missing), because suheaven is AWOL
- iOS audio output and video display, because author refuses the license change
- Equalizer and compressor, because Ronald Wright is AWOL
- Mono, Headphone and Dolby, because author refuses the license change
- hqdn3d and yadif, because they are from MPlayer/libavfilter
- remoteosd, because it derives from RealVNC code
- MMX optimisations, because Ollie Lho, from SiS, is AWOL
- Rotate, because it depends on GPL motion
Nota Bene:
- Some modules depend on GPL-only libraries, a LGPL module does not mean
that the resulting binary module will be LGPL.
Libraries affected would include liba52, libdvdcss, libdvdnav, libdvdread,
faad2, libdca, libmad, libmpeg2, libpostproc, SRC, sid, zvbi and probably others.
