ffmpeg | branch: release/1.1 | Michael Niedermayer <michaelni at gmx.at> | Fri Oct 11 14:49:50 2013 +0200| [e31e66948d0a9a3f98afdb49c63208caefed5a61] | committer: Michael Niedermayer

Delete changelog

The merges have filled the changelog of the 1.1 branch with bugfix
entries that ffmpeg 1.1 was never affected by or that where fixed
long ago.
No one has cleaned this mess up and its better to have no changelog file
than one that is 80% wrong.
If someone wants to clean this up, thats of course very welcome, aka yes
patches and pull requests welcome!

-version 0.9:
-
-- openal input device added
-- boxblur filter added
-- BWF muxer
-- Flash Screen Video 2 decoder
-- lavfi input device added
-- added avconv, which is almost the same for now, except
-for a few incompatible changes in the options, which will hopefully make them
-easier to use. The changes are:
-    * The options placement is now strictly enforced! While in theory the
-      options for ffmpeg should be given in [input options] -i INPUT [output
-      options] OUTPUT order, in practice it was possible to give output options
-      before the -i and it mostly worked. Except when it didn't - the behavior was
-      a bit inconsistent. In avconv, it is not possible to mix input and output
-      options. All non-global options are reset after an input or output filename.
-    * All per-file options are now truly per-file - they apply only to the next
-      input or output file and specifying different values for different files
-      will now work properly (notably -ss and -t options).
-    * All per-stream options are now truly per-stream - it is possible to
-      specify which stream(s) should a given option apply to. See the Stream
-      specifiers section in the avconv manual for details.
-    * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
-      sense that they're specified after the output filename instead of before,
-      like all other options. In avconv this irregularity is removed, all options
-      apply to the next input or output file.
-    * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
-      irregular and highly confusing, they were also redundant. In avconv the -map
-      option will create new streams in the output file and map input streams to
-      them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
-      each stream in the first input file.
-    * The -map option now has slightly different and more powerful syntax:
-        + Colons (':') are used to separate file index/stream type/stream index
-          instead of dots. Comma (',') is used to separate the sync stream instead
-          of colon.. This is done for consistency with other options.
-        + It's possible to specify stream type. E.g. -map 0:a:2 creates an
-          output stream from the third input audio stream.
-        + Omitting the stream index now maps all the streams of the given type,
-          not just the first. E.g. -map 0:s creates output streams for all the
-          subtitle streams in the first input file.
-        + Since -map can now match multiple streams, negative mappings were
-          introduced. Negative mappings disable some streams from an already
-          defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
-          all the stream in the first input file, except for the second audio
-          stream'.
-    * There is a new option -c (or -codec) for choosing the decoder/encoder to
-      use, which allows to precisely specify target stream(s) consistently with
-      other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
-      libvorbis sets the codec for the first audio stream and -c copy copies all
-      the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
-      aliases to -c:v/a/s
-    * It is now possible to precisely specify which stream should an AVOption
-      apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
-      -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
-      syntax is deprecated and will stop working soon.
-    * -map_chapters now takes only an input file index and applies to the next
-      output file. This is consistent with how all the other options work.
-    * -map_metadata now takes only an input metadata specifier and applies to
-      the next output file. Output metadata specifier is now part of the option
-      name, similarly to the AVOptions/map/codec feature above.
-    * -metadata can now be used to set metadata on streams and chapters, e.g.
-      -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
-      This made -vlang/-alang/-slang options redundant, so they were removed.
-    * -qscale option now uses stream specifiers and applies to all streams, not
-      just video. I.e. plain -qscale number would now apply to all streams. To get
-      the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
-      and -aq is now an alias for -q:a.
-    * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
-      uses stream specifiers. Use -bsf:v/a/s instead of the old options.
-    * -itsscale option now uses stream specifiers, so its argument is only the
-      scale parameter.
-    * -intra option was removed, use -g 0 for the same effect.
-    * -psnr option was removed, use -flags +psnr for the same effect.
-    * -vf option is now an alias to the new -filter option, which uses stream specifiers.
-    * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
-    * -vtag/-atag/-stag options are now aliases to the new -tag option.

-
-
-version 0.4.4:
-
-- fixed some std header definitions (Bjorn Lindgren
-  <bjorn.e.lindgren at telia.com>).
-- added MPEG demuxer (MPEG-1 and 2 compatible).
-- added ASF demuxer
-- added prototype RM demuxer
-- added AC3 decoding (done with libac3 by Aaron Holtzman)
-- added decoding codec parameter guessing (.e.g. for MPEG, because the
-  header does not include them)
-- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
-  play them (only tested video)
-- fixed H.263 white bug
-- fixed phase rounding in img resample filter
-- add MMX code for polyphase img resample filter
-- added CPU autodetection
-- added generic title/author/copyright/comment string handling (ASF and RM
-  use them)
-- added SWF demux to extract MP3 track (not usable yet because no MP3
-  decoder)
-- added fractional frame rate support
-- codecs are no longer searched by read_header() (should fix ffserver
-  segfault)
-
-
-version 0.4.3:
-
-- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
-- fixed raw yuv output
-- added motion rounding support in MPEG-4
-- fixed motion bug rounding in MSMPEG4
-- added B-frame handling in video core
-- added full MPEG-1 decoding support
-- added partial (frame only) MPEG-2 support
-- changed the FOURCC code for H.263 to "U263" to be able to see the
-  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
-  this +codec ;) (JuanJo).
-- Halfpel motion estimation after MB type selection (JuanJo)
-- added pgm and .Y.U.V output format
-- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
-  output.
-- added pgmpipe I/O format (original patch from Martin Aumueller
-  <lists at reserv.at>, but changed completely since we use a format
-  instead of a protocol)
-
-
-version 0.4.2:
-
-- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
-  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
-  missing. MSMPEG4 support is complete.
-- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
-  can decode ffmpeg MPEGs :-)).
-- added libavcodec API documentation (see apiexample.c).
-- fixed image polyphase bug (the bottom of some images could be
-  greenish)
-- added support for non clipped motion vectors (decoding only)
-  and image sizes non-multiple of 16
-- added support for AC prediction (decoding only)
-- added file overwrite confirmation (can be disabled with -y)
-- added custom size picture to H.263 using H.263+ (Juanjo)
-
-
-version 0.4.1:
-
-- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
-  of AVI and ASF to DIV3.
-- added -me option to set motion estimation method
-  (default=log). suppressed redundant -hq option.
-- added options -acodec and -vcodec to force a given codec (useful for
-  AVI for example)
-- fixed -an option
-- improved dct_quantize speed
-- factorized some motion estimation code
-
-
-version 0.4.0:
-
-- removing grab code from ffserver and moved it to ffmpeg. Added
-  multistream support to ffmpeg.
-- added timeshifting support for live feeds (option ?date=xxx in the
-  URL)
-- added high quality image resize code with polyphase filter (need
-  mmx/see optimization). Enable multiple image size support in ffserver.
-- added multi live feed support in ffserver
-- suppressed master feature from ffserver (it should be done with an
-  external program which opens the .ffm url and writes it to another
-  ffserver)
-- added preliminary support for video stream parsing (WAV and AVI half
-  done). Added proper support for audio/video file conversion in
-  ffmpeg.
-- added preliminary support for video file sending from ffserver
-- redesigning I/O subsystem: now using URL based input and output
-  (see avio.h)
-- added WAV format support
-- added "tty user interface" to ffmpeg to stop grabbing gracefully
-- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
-  (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
-- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
-- added new motion estimation algorithms, log and phods (Juanjo)
-- changed directories: libav for format handling, libavcodec for
-  codecs
-
-
-version 0.3.4:
-
-- added stereo in MPEG audio encoder
-
-
-version 0.3.3:
-
-- added 'high quality' mode which use motion vectors. It can be used in
-  real time at low resolution.
-- fixed rounding problems which caused quality problems at high
-  bitrates and large GOP size
-
-
-version 0.3.2: small fixes
-
-- ASF fixes
-- put_seek bug fix
-
-
-version 0.3.1: added avi/divx support
-
-- added AVI support
-- added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
-- added sound for flash format (not tested)
-
-
-version 0.3: initial public release
