						||
| 
								 | 
							
								- openal input device added

								- 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 makes it possible 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.

								 | 
							
								  header does not include them)
							 | 
						||

| 
								 | 
							
								- added fractional frame rate support
							 |

| 
								 | 
							
								  segfault)
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								
							 | 
						||

							 | 
						||
| 
								 | 
							
								  +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 pgmpipe I/O format (original patch from Martin Aumueller
							 |

| 
								 | 
							
								  instead of a protocol)

								 | 
							
								
							 | 
						||
|

							 | 
						||
|

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

							 | 
						||
| 
								 | 
							
								  missing. MSMPEG4 support is complete.
							 | 
						||
| 
								 | 
							
								- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
							 | 
						||
| 
								 | 
							
								  can decode ffmpeg MPEGs :-)).
							 |

| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								
							 | 
						||

							 | 
						||
| 
								 | 
							
								  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
							 | 
						||
| 
								 |

							 | 
						||
| 
								 | 
							
								  multistream support to ffmpeg.
							 | 
						||

								 | 
							
								- added timeshifting support for live feeds (option ?date=xxx in the
							 | 
						||
| 
								 | 
							
								  URL)
							 | 
						||
| 
								 |

							 | 
						||
| 
								 | 
							
								- 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

						||
| 
								 | 
							
								- fixed rounding problems which caused quality problems at high
							 | 
						||
| 
								 | 
							
								  bitrates and large GOP size
							 |
