  1068. version 0.9:

  1069. 

  1070. - openal input device added

  1071. - boxblur filter added

  1072. - BWF muxer

  1073. - Flash Screen Video 2 decoder

  1074. - lavfi input device added

  1075. - added avconv, which is almost the same for now, except

  1076. for a few incompatible changes in the options, which will hopefully make them

  1077. easier to use. The changes are:

  1078.     * The options placement is now strictly enforced! While in theory the

  1079.       options for ffmpeg should be given in [input options] -i INPUT [output

  1080.       options] OUTPUT order, in practice it was possible to give output options

  1081.       before the -i and it mostly worked. Except when it didn't - the behavior was

  1082.       a bit inconsistent. In avconv, it is not possible to mix input and output

  1083.       options. All non-global options are reset after an input or output filename.

  1084.     * All per-file options are now truly per-file - they apply only to the next

  1085.       input or output file and specifying different values for different files

  1086.       will now work properly (notably -ss and -t options).

  1087.     * All per-stream options are now truly per-stream - it is possible to

  1088.       specify which stream(s) should a given option apply to. See the Stream

  1089.       specifiers section in the avconv manual for details.

  1090.     * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the

  1091.       sense that they're specified after the output filename instead of before,

  1092.       like all other options. In avconv this irregularity is removed, all options

  1093.       apply to the next input or output file.

  1094.     * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they

  1095.       irregular and highly confusing, they were also redundant. In avconv the -map

  1096.       option will create new streams in the output file and map input streams to

  1097.       them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for

  1098.       each stream in the first input file.

  1099.     * The -map option now has slightly different and more powerful syntax:

  1100.         + Colons (':') are used to separate file index/stream type/stream index

  1101.           instead of dots. Comma (',') is used to separate the sync stream instead

  1102.           of colon.. This is done for consistency with other options.

  1103.         + It's possible to specify stream type. E.g. -map 0:a:2 creates an

  1104.           output stream from the third input audio stream.

  1105.         + Omitting the stream index now maps all the streams of the given type,

  1106.           not just the first. E.g. -map 0:s creates output streams for all the

  1107.           subtitle streams in the first input file.

  1108.         + Since -map can now match multiple streams, negative mappings were

  1109.           introduced. Negative mappings disable some streams from an already

  1110.           defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for

  1111.           all the stream in the first input file, except for the second audio

  1112.           stream'.

  1113.     * There is a new option -c (or -codec) for choosing the decoder/encoder to

  1114.       use, which makes it possible to precisely specify target stream(s) consistently with

  1115.       other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0

  1116.       libvorbis sets the codec for the first audio stream and -c copy copies all

  1117.       the streams without reencoding. Old -vcodec/-acodec/-scodec options are now

  1118.       aliases to -c:v/a/s

  1119.     * It is now possible to precisely specify which stream should an AVOption

  1120.       apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while

  1121.       -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k

  1122.       syntax is deprecated and will stop working soon.

  1123.     * -map_chapters now takes only an input file index and applies to the next

  1124.       output file. This is consistent with how all the other options work.

  1125.     * -map_metadata now takes only an input metadata specifier and applies to

  1126.       the next output file. Output metadata specifier is now part of the option

  1127.       name, similarly to the AVOptions/map/codec feature above.

  1128.     * -metadata can now be used to set metadata on streams and chapters, e.g.

  1129.       -metadata:s:1 language=eng sets the language of the first stream to 'eng'.

  1130.       This made -vlang/-alang/-slang options redundant, so they were removed.

  1131.     * -qscale option now uses stream specifiers and applies to all streams, not

  1132.       just video. I.e. plain -qscale number would now apply to all streams. To get

  1133.       the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale

  1134.       and -aq is now an alias for -q:a.

  1135.     * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which

  1136.       uses stream specifiers. Use -bsf:v/a/s instead of the old options.

  1137.     * -itsscale option now uses stream specifiers, so its argument is only the

  1138.       scale parameter.

  1139.     * -intra option was removed, use -g 0 for the same effect.

  1140.     * -psnr option was removed, use -flags +psnr for the same effect.

  1141.     * -vf option is now an alias to the new -filter option, which uses stream specifiers.

  1142.     * -vframes/-aframes/-dframes options are now aliases to the new -frames option.

  1143.     * -vtag/-atag/-stag options are now aliases to the new -tag option.

  1839. 

  1840. - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec

  1841.   of AVI and ASF to DIV3.

  1842. - added -me option to set motion estimation method

  1843.   (default=log). suppressed redundant -hq option.

  1844. - added options -acodec and -vcodec to force a given codec (useful for

  1845.   AVI for example)

  1846. - fixed -an option

  1847. - improved dct_quantize speed

  1848. - factorized some motion estimation code

  1849. 

  1850. 

  1851. version 0.4.0:

  1852. 

  1853. - removing grab code from ffserver and moved it to ffmpeg. Added

  1854.   multistream support to ffmpeg.

  1855. - added timeshifting support for live feeds (option ?date=xxx in the

  1856.   URL)

  1857. - added high quality image resize code with polyphase filter (need

  1858.   mmx/see optimization). Enable multiple image size support in ffserver.

  1859. - added multi live feed support in ffserver

  1860. - suppressed master feature from ffserver (it should be done with an

  1861.   external program which opens the .ffm url and writes it to another

  1862.   ffserver)

  1863. - added preliminary support for video stream parsing (WAV and AVI half

  1864.   done). Added proper support for audio/video file conversion in

  1865.   ffmpeg.

  1866. - added preliminary support for video file sending from ffserver

  1867. - redesigning I/O subsystem: now using URL based input and output

  1868.   (see avio.h)

  1869. - added WAV format support

  1870. - added "tty user interface" to ffmpeg to stop grabbing gracefully

  1871. - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)

  1872.   (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)

  1873. - added MMX DCT from mpeg2_movie 1.5 (Juanjo)

  1874. - added new motion estimation algorithms, log and phods (Juanjo)

  1875. - changed directories: libav for format handling, libavcodec for

  1876.   codecs

  1877. 

  1878. 

  1879. version 0.3.4:

  1880. 

  1881. - added stereo in MPEG audio encoder

  1883. 

  1884. version 0.3.3:

  1885. 

  1886. - added 'high quality' mode which use motion vectors. It can be used in

  1887.   real time at low resolution.

  1888. - fixed rounding problems which caused quality problems at high

  1889.   bitrates and large GOP size

  1890. 

  1891. 

  1892. version 0.3.2: small fixes

  1893. 

  1894. - ASF fixes

  1895. - put_seek bug fix

  1896. 

  1897. 

  1898. version 0.3.1: added avi/divx support

  1899. 

  1900. - added AVI support

  1901. - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec

  1902. - added sound for flash format (not tested)
