  1070. version 0.9:

  1071. 

  1072. - openal input device added

  1073. - boxblur filter added

  1074. - BWF muxer

  1075. - Flash Screen Video 2 decoder

  1076. - lavfi input device added

  1077. - added avconv, which is almost the same for now, except

  1078. for a few incompatible changes in the options, which will hopefully make them

  1079. easier to use. The changes are:

  1080.     * The options placement is now strictly enforced! While in theory the

  1081.       options for ffmpeg should be given in [input options] -i INPUT [output

  1082.       options] OUTPUT order, in practice it was possible to give output options

  1083.       before the -i and it mostly worked. Except when it didn't - the behavior was

  1084.       a bit inconsistent. In avconv, it is not possible to mix input and output

  1085.       options. All non-global options are reset after an input or output filename.

  1086.     * All per-file options are now truly per-file - they apply only to the next

  1087.       input or output file and specifying different values for different files

  1088.       will now work properly (notably -ss and -t options).

  1089.     * All per-stream options are now truly per-stream - it is possible to

  1090.       specify which stream(s) should a given option apply to. See the Stream

  1091.       specifiers section in the avconv manual for details.

  1092.     * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the

  1093.       sense that they're specified after the output filename instead of before,

  1094.       like all other options. In avconv this irregularity is removed, all options

  1095.       apply to the next input or output file.

  1096.     * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they

  1097.       irregular and highly confusing, they were also redundant. In avconv the -map

  1098.       option will create new streams in the output file and map input streams to

  1099.       them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for

  1100.       each stream in the first input file.

  1101.     * The -map option now has slightly different and more powerful syntax:

  1102.         + Colons (':') are used to separate file index/stream type/stream index

  1103.           instead of dots. Comma (',') is used to separate the sync stream instead

  1104.           of colon.. This is done for consistency with other options.

  1105.         + It's possible to specify stream type. E.g. -map 0:a:2 creates an

  1106.           output stream from the third input audio stream.

  1107.         + Omitting the stream index now maps all the streams of the given type,

  1108.           not just the first. E.g. -map 0:s creates output streams for all the

  1109.           subtitle streams in the first input file.

  1110.         + Since -map can now match multiple streams, negative mappings were

  1111.           introduced. Negative mappings disable some streams from an already

  1112.           defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for

  1113.           all the stream in the first input file, except for the second audio

  1114.           stream'.

  1115.     * There is a new option -c (or -codec) for choosing the decoder/encoder to

  1116.       use, which makes it possible to precisely specify target stream(s) consistently with

  1117.       other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0

  1118.       libvorbis sets the codec for the first audio stream and -c copy copies all

  1119.       the streams without reencoding. Old -vcodec/-acodec/-scodec options are now

  1120.       aliases to -c:v/a/s

  1121.     * It is now possible to precisely specify which stream should an AVOption

  1122.       apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while

  1123.       -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k

  1124.       syntax is deprecated and will stop working soon.

  1125.     * -map_chapters now takes only an input file index and applies to the next

  1126.       output file. This is consistent with how all the other options work.

  1127.     * -map_metadata now takes only an input metadata specifier and applies to

  1128.       the next output file. Output metadata specifier is now part of the option

  1129.       name, similarly to the AVOptions/map/codec feature above.

  1130.     * -metadata can now be used to set metadata on streams and chapters, e.g.

  1131.       -metadata:s:1 language=eng sets the language of the first stream to 'eng'.

  1132.       This made -vlang/-alang/-slang options redundant, so they were removed.

  1133.     * -qscale option now uses stream specifiers and applies to all streams, not

  1134.       just video. I.e. plain -qscale number would now apply to all streams. To get

  1135.       the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale

  1136.       and -aq is now an alias for -q:a.

  1137.     * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which

  1138.       uses stream specifiers. Use -bsf:v/a/s instead of the old options.

  1139.     * -itsscale option now uses stream specifiers, so its argument is only the

  1140.       scale parameter.

  1141.     * -intra option was removed, use -g 0 for the same effect.

  1142.     * -psnr option was removed, use -flags +psnr for the same effect.

  1143.     * -vf option is now an alias to the new -filter option, which uses stream specifiers.

  1144.     * -vframes/-aframes/-dframes options are now aliases to the new -frames option.

  1145.     * -vtag/-atag/-stag options are now aliases to the new -tag option.

  1841. 

  1842. - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec

  1843.   of AVI and ASF to DIV3.

  1844. - added -me option to set motion estimation method

  1845.   (default=log). suppressed redundant -hq option.

  1846. - added options -acodec and -vcodec to force a given codec (useful for

  1847.   AVI for example)

  1848. - fixed -an option

  1849. - improved dct_quantize speed

  1850. - factorized some motion estimation code

  1851. 

  1852. 

  1853. version 0.4.0:

  1854. 

  1855. - removing grab code from ffserver and moved it to ffmpeg. Added

  1856.   multistream support to ffmpeg.

  1857. - added timeshifting support for live feeds (option ?date=xxx in the

  1858.   URL)

  1859. - added high quality image resize code with polyphase filter (need

  1860.   mmx/see optimization). Enable multiple image size support in ffserver.

  1861. - added multi live feed support in ffserver

  1862. - suppressed master feature from ffserver (it should be done with an

  1863.   external program which opens the .ffm url and writes it to another

  1864.   ffserver)

  1865. - added preliminary support for video stream parsing (WAV and AVI half

  1866.   done). Added proper support for audio/video file conversion in

  1867.   ffmpeg.

  1868. - added preliminary support for video file sending from ffserver

  1869. - redesigning I/O subsystem: now using URL based input and output

  1870.   (see avio.h)

  1871. - added WAV format support

  1872. - added "tty user interface" to ffmpeg to stop grabbing gracefully

  1873. - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)

  1875. - added MMX DCT from mpeg2_movie 1.5 (Juanjo)

  1876. - added new motion estimation algorithms, log and phods (Juanjo)

  1877. - changed directories: libav for format handling, libavcodec for

  1878.   codecs

  1879. 

  1880. 

  1881. version 0.3.4:

  1885. 

  1886. version 0.3.3:

  1887. 

  1888. - added 'high quality' mode which use motion vectors. It can be used in

  1889.   real time at low resolution.

  1890. - fixed rounding problems which caused quality problems at high

  1891.   bitrates and large GOP size

  1892. 

  1893. 

  1894. version 0.3.2: small fixes

  1895. 

  1896. - ASF fixes

  1897. - put_seek bug fix

  1898.

  1901. 

  1902. - added AVI support
