version 0.9:

- openal input device 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 makes it possible 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.
