openal input device added
boxblur filter added
BWF muxer
Flash Screen Video 2 decoder
lavfi input device added
added avconv, which is almost the same for now, except
for a few incompatible changes in the options, which will hopefully make them
easier to use. The changes are
The options placement is now strictly enforced! While in theory the
options for ffmpeg should be given in [input options] -i INPUT [output
options] OUTPUT order, in practice it was possible to give output options
before the -i and it mostly worked. Except when it didn't - the behavior was
a bit inconsistent. In avconv, it is not possible to mix input and output
options. All non-global options are reset after an input or output filename
All per-file options are now truly per-file - they apply only to the next
input or output file and specifying different values for different files
will now work properly (notably -ss and -t options)
All per-stream options are now truly per-stream - it is possible to
specify which stream(s) should a given option apply to. See the Stream
specifiers section in the avconv manual for details
In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
sense that they're specified after the output filename instead of before
like all other options. In avconv this irregularity is removed, all options
apply to the next input or output file
newvideo/-newaudio/-newsubtitle options were removed. Not only were they
irregular and highly confusing, they were also redundant. In avconv the -map
option will create new streams in the output file and map input streams to
them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
each stream in the first input file
The -map option now has slightly different and more powerful syntax
Colons (':') are used to separate file index/stream type/stream index
instead of dots. Comma (',') is used to separate the sync stream instead
of colon.. This is done for consistency with other options
It's possible to specify stream type. E.g. -map 0:a:2 creates an
output stream from the third input audio stream
Omitting the stream index now maps all the streams of the given type
not just the first. E.g. -map 0:s creates output streams for all the
subtitle streams in the first input file
Since -map can now match multiple streams, negative mappings were
introduced. Negative mappings disable some streams from an already
defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
all the stream in the first input file, except for the second audio
stream'
There is a new option -c (or -codec) for choosing the decoder/encoder to
use, which allows to precisely specify target stream(s) consistently with
other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
libvorbis sets the codec for the first audio stream and -c copy copies all
the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
aliases to -c:v/a/s
It is now possible to precisely specify which stream should an AVOption
apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
syntax is deprecated and will stop working soon
map_chapters now takes only an input file index and applies to the next
output file. This is consistent with how all the other options work
map_metadata now takes only an input metadata specifier and applies to
the next output file. Output metadata specifier is now part of the option
name, similarly to the AVOptions/map/codec feature above
metadata can now be used to set metadata on streams and chapters, e.g
metadata:s:1 language=eng sets the language of the first stream to 'eng'
This made -vlang/-alang/-slang options redundant, so they were removed
qscale option now uses stream specifiers and applies to all streams, not
just video. I.e. plain -qscale number would now apply to all streams. To get
the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
and -aq is now an alias for -q:a
vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
uses stream specifiers. Use -bsf:v/a/s instead of the old options
itsscale option now uses stream specifiers, so its argument is only the
scale parameter
intra option was removed, use -g 0 for the same effect
psnr option was removed, use -flags +psnr for the same effect
vf option is now an alias to the new -filter option, which uses stream specifiers
vframes/-aframes/-dframes options are now aliases to the new -frames option
vtag/-atag/-stag options are now aliases to the new -tag option
