 | 
					
						
							|  |  |  | 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 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. |

							|  |  |  |   (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 |

							|  |  |  |   (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 |

							|  |  |  |   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 |
