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. +- XMV demuxer +- Windows Media Image decoder +- LATM muxer/demuxer +- showinfo filter +- split filter +- libcdio-paranoia input device for audio CD grabbing +- select filter +- Apple ProRes decoder +- CELT in Ogg demuxing +- VC-1 interlaced decoding +- lut, lutrgb, and lutyuv filters +- boxblur filter +- Ut Video decoder +- Speex encoding via libspeex +- 4:2:2 H.264 decoding support +- 4:2:2 and 4:4:4 H.264 encoding with libx264 +- Pulseaudio input device +- replacement Indeo 3 decoder +- TLS/SSL and HTTPS protocol support +- AVOptions API rewritten and documented +- most of CODEC_FLAG2_*, some CODEC_FLAG_* and many codec-specific fields in + AVCodecContext deprecated.
