  1092. version 0.9:

  1093. 

  1094. - openal input device added

  1095. - boxblur filter added

  1096. - BWF muxer

  1097. - Flash Screen Video 2 decoder

  1098. - lavfi input device added

  1099. - added avconv, which is almost the same for now, except

  1100. for a few incompatible changes in the options, which will hopefully make them

  1101. easier to use. The changes are:

  1102.     * The options placement is now strictly enforced! While in theory the

  1103.       options for ffmpeg should be given in [input options] -i INPUT [output

  1104.       options] OUTPUT order, in practice it was possible to give output options

  1105.       before the -i and it mostly worked. Except when it didn't - the behavior was

  1106.       a bit inconsistent. In avconv, it is not possible to mix input and output

  1107.       options. All non-global options are reset after an input or output filename.

  1108.     * All per-file options are now truly per-file - they apply only to the next

  1109.       input or output file and specifying different values for different files

  1110.       will now work properly (notably -ss and -t options).

  1111.     * All per-stream options are now truly per-stream - it is possible to

  1112.       specify which stream(s) should a given option apply to. See the Stream

  1113.       specifiers section in the avconv manual for details.

  1114.     * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the

  1115.       sense that they're specified after the output filename instead of before,

  1116.       like all other options. In avconv this irregularity is removed, all options

  1117.       apply to the next input or output file.

  1118.     * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they

  1119.       irregular and highly confusing, they were also redundant. In avconv the -map

  1120.       option will create new streams in the output file and map input streams to

  1121.       them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for

  1122.       each stream in the first input file.

  1123.     * The -map option now has slightly different and more powerful syntax:

  1124.         + Colons (':') are used to separate file index/stream type/stream index

  1125.           instead of dots. Comma (',') is used to separate the sync stream instead

  1126.           of colon.. This is done for consistency with other options.

  1127.         + It's possible to specify stream type. E.g. -map 0:a:2 creates an

  1128.           output stream from the third input audio stream.

  1129.         + Omitting the stream index now maps all the streams of the given type,

  1130.           not just the first. E.g. -map 0:s creates output streams for all the

  1131.           subtitle streams in the first input file.

  1132.         + Since -map can now match multiple streams, negative mappings were

  1133.           introduced. Negative mappings disable some streams from an already

  1134.           defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for

  1135.           all the stream in the first input file, except for the second audio

  1136.           stream'.

  1137.     * There is a new option -c (or -codec) for choosing the decoder/encoder to

  1138.       use, which makes it possible to precisely specify target stream(s) consistently with

  1139.       other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0

  1140.       libvorbis sets the codec for the first audio stream and -c copy copies all

  1141.       the streams without reencoding. Old -vcodec/-acodec/-scodec options are now

  1142.       aliases to -c:v/a/s

  1143.     * It is now possible to precisely specify which stream should an AVOption

  1144.       apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while

  1145.       -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k

  1146.       syntax is deprecated and will stop working soon.

  1147.     * -map_chapters now takes only an input file index and applies to the next

  1148.       output file. This is consistent with how all the other options work.

  1149.     * -map_metadata now takes only an input metadata specifier and applies to

  1150.       the next output file. Output metadata specifier is now part of the option

  1151.       name, similarly to the AVOptions/map/codec feature above.

  1152.     * -metadata can now be used to set metadata on streams and chapters, e.g.

  1153.       -metadata:s:1 language=eng sets the language of the first stream to 'eng'.

  1154.       This made -vlang/-alang/-slang options redundant, so they were removed.

  1155.     * -qscale option now uses stream specifiers and applies to all streams, not

  1156.       just video. I.e. plain -qscale number would now apply to all streams. To get

  1157.       the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale

  1158.       and -aq is now an alias for -q:a.

  1159.     * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which

  1160.       uses stream specifiers. Use -bsf:v/a/s instead of the old options.

  1161.     * -itsscale option now uses stream specifiers, so its argument is only the

  1162.       scale parameter.

  1163.     * -intra option was removed, use -g 0 for the same effect.

  1164.     * -psnr option was removed, use -flags +psnr for the same effect.

  1165.     * -vf option is now an alias to the new -filter option, which uses stream specifiers.

  1166.     * -vframes/-aframes/-dframes options are now aliases to the new -frames option.

  1167.     * -vtag/-atag/-stag options are now aliases to the new -tag option.

  1838. - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or

  1839.   output.

  1840. - added pgmpipe I/O format (original patch from Martin Aumueller

  1841.   <lists at reserv.at>, but changed completely since we use a format

  1842.   instead of a protocol)

  1843. 

  1844. 

  1845. version 0.4.2:

  1846. 

  1847. - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support

  1848.   (for OpenDivX) is almost complete: 8x8 MVs and rounding are

  1849.   missing. MSMPEG4 support is complete.

  1850. - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it

  1851.   can decode ffmpeg MPEGs :-)).

  1852. - added libavcodec API documentation (see apiexample.c).

  1853. - fixed image polyphase bug (the bottom of some images could be

  1854.   greenish)

  1855. - added support for non clipped motion vectors (decoding only)

  1856.   and image sizes non-multiple of 16

  1857. - added support for AC prediction (decoding only)

  1858. - added file overwrite confirmation (can be disabled with -y)

  1859. - added custom size picture to H.263 using H.263+ (Juanjo)

  1860. 

  1861. 

  1862. version 0.4.1:

  1863. 

  1864. - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec

  1865.   of AVI and ASF to DIV3.

  1866. - added -me option to set motion estimation method

  1867.   (default=log). suppressed redundant -hq option.

  1868. - added options -acodec and -vcodec to force a given codec (useful for

  1869.   AVI for example)

  1870. - fixed -an option

  1871. - improved dct_quantize speed

  1872. - factorized some motion estimation code

  1873. 

  1874. 

  1875. version 0.4.0:

  1876. 

  1877. - removing grab code from ffserver and moved it to ffmpeg. Added

  1878.   multistream support to ffmpeg.

  1879. - added timeshifting support for live feeds (option ?date=xxx in the

  1880.   URL)

  1881. - added high quality image resize code with polyphase filter (need

  1882.   mmx/see optimization). Enable multiple image size support in ffserver.

  1883. - added multi live feed support in ffserver

  1884. - suppressed master feature from ffserver (it should be done with an

  1885.   external program which opens the .ffm url and writes it to another

  1886.   ffserver)

  1887. - added preliminary support for video stream parsing (WAV and AVI half

  1888.   done). Added proper support for audio/video file conversion in

  1889.   ffmpeg.

  1890. - added preliminary support for video file sending from ffserver

  1891. - redesigning I/O subsystem: now using URL based input and output

  1892.   (see avio.h)

  1893. - added WAV format support

  1894. - added "tty user interface" to ffmpeg to stop grabbing gracefully

  1895. - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)

  1896.   (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)

  1897. - added MMX DCT from mpeg2_movie 1.5 (Juanjo)

  1898. - added new motion estimation algorithms, log and phods (Juanjo)

  1899. - changed directories: libav for format handling, libavcodec for

  1900.   codecs

  1901. 

  1902. 

  1903. version 0.3.4:

  1904. 

  1905. - added stereo in MPEG audio encoder

  1906. 

  1907. 

  1908. version 0.3.3:

  1909. 

  1910. - added 'high quality' mode which use motion vectors. It can be used in

  1911.   real time at low resolution.

  1912. - fixed rounding problems which caused quality problems at high

  1913.   bitrates and large GOP size

  1914. 

  1915. 

  1916. version 0.3.2: small fixes

  1917. 

  1918. - ASF fixes

  1919. - put_seek bug fix

  1920. 

  1921. 

  1922. version 0.3.1: added avi/divx support

  1923. 

  1924. - added AVI support

  1925. - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec

  1926. - added sound for flash format (not tested)

  1927.
