1327version 0.9:
1328
1329- openal input device added
1330- boxblur filter added
1331- BWF muxer
1332- Flash Screen Video 2 decoder
1333- lavfi input device added
1334- added avconv, which is almost the same for now, except
1335for a few incompatible changes in the options, which will hopefully make them
1336easier to use. The changes are:
1337    * The options placement is now strictly enforced! While in theory the
1338      options for ffmpeg should be given in [input options] -i INPUT [output
1339      options] OUTPUT order, in practice it was possible to give output options
1340      before the -i and it mostly worked. Except when it didn't - the behavior was
1341      a bit inconsistent. In avconv, it is not possible to mix input and output
1342      options. All non-global options are reset after an input or output filename.
1343    * All per-file options are now truly per-file - they apply only to the next
1344      input or output file and specifying different values for different files
1345      will now work properly (notably -ss and -t options).
1346    * All per-stream options are now truly per-stream - it is possible to
1347      specify which stream(s) should a given option apply to. See the Stream
1348      specifiers section in the avconv manual for details.
1349    * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
1350      sense that they're specified after the output filename instead of before,
1351      like all other options. In avconv this irregularity is removed, all options
1352      apply to the next input or output file.
1353    * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
1354      irregular and highly confusing, they were also redundant. In avconv the -map
1355      option will create new streams in the output file and map input streams to
1356      them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
1357      each stream in the first input file.
1358    * The -map option now has slightly different and more powerful syntax:
1359        + Colons (':') are used to separate file index/stream type/stream index
1360          instead of dots. Comma (',') is used to separate the sync stream instead
1361          of colon.. This is done for consistency with other options.
1362        + It's possible to specify stream type. E.g. -map 0:a:2 creates an
1363          output stream from the third input audio stream.
1364        + Omitting the stream index now maps all the streams of the given type,
1365          not just the first. E.g. -map 0:s creates output streams for all the
1366          subtitle streams in the first input file.
1367        + Since -map can now match multiple streams, negative mappings were
1368          introduced. Negative mappings disable some streams from an already
1369          defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
1370          all the stream in the first input file, except for the second audio
1371          stream'.
1372    * There is a new option -c (or -codec) for choosing the decoder/encoder to
1373      use, which makes it possible to precisely specify target stream(s) consistently with
1374      other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
1375      libvorbis sets the codec for the first audio stream and -c copy copies all
1376      the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
1377      aliases to -c:v/a/s
1378    * It is now possible to precisely specify which stream should an AVOption
1379      apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
1380      -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
1381      syntax is deprecated and will stop working soon.
1382    * -map_chapters now takes only an input file index and applies to the next
1383      output file. This is consistent with how all the other options work.
1384    * -map_metadata now takes only an input metadata specifier and applies to
1385      the next output file. Output metadata specifier is now part of the option
1386      name, similarly to the AVOptions/map/codec feature above.
1387    * -metadata can now be used to set metadata on streams and chapters, e.g.
1388      -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
1389      This made -vlang/-alang/-slang options redundant, so they were removed.
1390    * -qscale option now uses stream specifiers and applies to all streams, not
1391      just video. I.e. plain -qscale number would now apply to all streams. To get
1392      the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
1393      and -aq is now an alias for -q:a.
1394    * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
1395      uses stream specifiers. Use -bsf:v/a/s instead of the old options.
1396    * -itsscale option now uses stream specifiers, so its argument is only the
1397      scale parameter.
1398    * -intra option was removed, use -g 0 for the same effect.
1399    * -psnr option was removed, use -flags +psnr for the same effect.
1400    * -vf option is now an alias to the new -filter option, which uses stream specifiers.
1401    * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
1402    * -vtag/-atag/-stag options are now aliases to the new -tag option.

2100  of AVI and ASF to DIV3.
2101- added -me option to set motion estimation method
2102  (default=log). suppressed redundant -hq option.

2117  mmx/see optimization). Enable multiple image size support in ffserver.
2118- added multi live feed support in ffserver
2119- suppressed master feature from ffserver (it should be done with an
2120  external program which opens the .ffm url and writes it to another
2121  ffserver)
2122- added preliminary support for video stream parsing (WAV and AVI half
2123  done). Added proper support for audio/video file conversion in
2124  ffmpeg.
