  1591. 

  1592. - openal input device added

  1593. - boxblur filter added

  1594. - BWF muxer

  1595. - Flash Screen Video 2 decoder

  1596. - lavfi input device added

  1597. - added avconv, which is almost the same for now, except

  1598. for a few incompatible changes in the options, which will hopefully make them

  1599. easier to use. The changes are:

  1600.     * The options placement is now strictly enforced! While in theory the

  1601.       options for ffmpeg should be given in [input options] -i INPUT [output

  1602.       options] OUTPUT order, in practice it was possible to give output options

  1603.       before the -i and it mostly worked. Except when it didn't - the behavior was

  1604.       a bit inconsistent. In avconv, it is not possible to mix input and output

  1605.       options. All non-global options are reset after an input or output filename.

  1606.     * All per-file options are now truly per-file - they apply only to the next

  1607.       input or output file and specifying different values for different files

  1608.       will now work properly (notably -ss and -t options).

  1609.     * All per-stream options are now truly per-stream - it is possible to

  1610.       specify which stream(s) should a given option apply to. See the Stream

  1611.       specifiers section in the avconv manual for details.

  1612.     * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the

  1613.       sense that they're specified after the output filename instead of before,

  1614.       like all other options. In avconv this irregularity is removed, all options

  1615.       apply to the next input or output file.

  1616.     * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they

  1617.       irregular and highly confusing, they were also redundant. In avconv the -map

  1618.       option will create new streams in the output file and map input streams to

  1619.       them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for

  1620.       each stream in the first input file.

  1621.     * The -map option now has slightly different and more powerful syntax:

  1622.         + Colons (':') are used to separate file index/stream type/stream index

  1623.           instead of dots. Comma (',') is used to separate the sync stream instead

  1624.           of colon.. This is done for consistency with other options.

  1625.         + It's possible to specify stream type. E.g. -map 0:a:2 creates an

  1626.           output stream from the third input audio stream.

  1627.         + Omitting the stream index now maps all the streams of the given type,

  1628.           not just the first. E.g. -map 0:s creates output streams for all the

  1629.           subtitle streams in the first input file.

  1630.         + Since -map can now match multiple streams, negative mappings were

  1631.           introduced. Negative mappings disable some streams from an already

  1632.           defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for

  1633.           all the stream in the first input file, except for the second audio

  1634.           stream'.

  1635.     * There is a new option -c (or -codec) for choosing the decoder/encoder to

  1636.       use, which makes it possible to precisely specify target stream(s) consistently with

  1637.       other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0

  1638.       libvorbis sets the codec for the first audio stream and -c copy copies all

  1639.       the streams without reencoding. Old -vcodec/-acodec/-scodec options are now

  1640.       aliases to -c:v/a/s

  1641.     * It is now possible to precisely specify which stream should an AVOption

  1642.       apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while

  1643.       -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k

  1644.       syntax is deprecated and will stop working soon.

  1645.     * -map_chapters now takes only an input file index and applies to the next

  1646.       output file. This is consistent with how all the other options work.

  1647.     * -map_metadata now takes only an input metadata specifier and applies to

  1648.       the next output file. Output metadata specifier is now part of the option

  1649.       name, similarly to the AVOptions/map/codec feature above.

  1650.     * -metadata can now be used to set metadata on streams and chapters, e.g.

  1651.       -metadata:s:1 language=eng sets the language of the first stream to 'eng'.

  1652.       This made -vlang/-alang/-slang options redundant, so they were removed.

  1653.     * -qscale option now uses stream specifiers and applies to all streams, not

  1654.       just video. I.e. plain -qscale number would now apply to all streams. To get

  1655.       the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale

  1656.       and -aq is now an alias for -q:a.

  1657.     * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which

  1658.       uses stream specifiers. Use -bsf:v/a/s instead of the old options.

  1659.     * -itsscale option now uses stream specifiers, so its argument is only the

  1660.       scale parameter.

  1661.     * -intra option was removed, use -g 0 for the same effect.

  1662.     * -psnr option was removed, use -flags +psnr for the same effect.

  1663.     * -vf option is now an alias to the new -filter option, which uses stream specifiers.

  1664.     * -vframes/-aframes/-dframes options are now aliases to the new -frames option.

  1665.     * -vtag/-atag/-stag options are now aliases to the new -tag option.

  2316.   decoder)

  2317. - added fractional frame rate support

  2318. - codecs are no longer searched by read_header() (should fix ffserver

  2319.   segfault)

  2331. - changed the FOURCC code for H.263 to "U263" to be able to see the

  2332.   +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with

  2333.   this +codec ;) (JuanJo).

  2334. - Halfpel motion estimation after MB type selection (JuanJo)

  2335. - added pgm and .Y.U.V output format

  2336. - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or

  2337.   output.

  2338. - added pgmpipe I/O format (original patch from Martin Aumueller

  2339.   <lists at reserv.at>, but changed completely since we use a format

  2340.   instead of a protocol)

  2341. 

  2342. 

  2343. version 0.4.2:

  2344. 

  2345. - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support

  2346.   (for OpenDivX) is almost complete: 8x8 MVs and rounding are

  2347.   missing. MSMPEG4 support is complete.

  2348. - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it

  2349.   can decode ffmpeg MPEGs :-)).

  2350. - added libavcodec API documentation (see apiexample.c).

  2351. - fixed image polyphase bug (the bottom of some images could be

  2352.   greenish)

  2353. - added support for non clipped motion vectors (decoding only)

  2354.   and image sizes non-multiple of 16

  2355. - added support for AC prediction (decoding only)

  2356. - added file overwrite confirmation (can be disabled with -y)

  2357. - added custom size picture to H.263 using H.263+ (Juanjo)

  2358. 

  2359. 

  2360. version 0.4.1:

  2361. 

  2362. - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec

  2363.   of AVI and ASF to DIV3.

  2364. - added -me option to set motion estimation method

  2365.   (default=log). suppressed redundant -hq option.

  2366. - added options -acodec and -vcodec to force a given codec (useful for

  2367.   AVI for example)

  2368. - fixed -an option

  2369. - improved dct_quantize speed

  2370. - factorized some motion estimation code

  2371. 

  2372.

  2376.   multistream support to ffmpeg.

  2377. - added timeshifting support for live feeds (option ?date=xxx in the

  2378.   URL)

  2379. - added high quality image resize code with polyphase filter (need

  2380.   mmx/see optimization). Enable multiple image size support in ffserver.

  2381. - added multi live feed support in ffserver

  2382. - suppressed master feature from ffserver (it should be done with an

  2383.   external program which opens the .ffm url and writes it to another

  2384.   ffserver)

  2385. - added preliminary support for video stream parsing (WAV and AVI half

  2386.   done). Added proper support for audio/video file conversion in

  2387.   ffmpeg.

  2388. - added preliminary support for video file sending from ffserver

  2409.   real time at low resolution.

  2410. - fixed rounding problems which caused quality problems at high

  2411.   bitrates and large GOP size

  2412.
