  975. easier to use. The changes are:

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

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

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

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

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

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

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

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

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

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

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

  987.       specifiers section in the avconv manual for details.

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

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

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

  991.       apply to the next input or output file.

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

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

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

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

  996.       each stream in the first input file.

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

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

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

  1000.           of colon.. This is done for consistency with other options.

  1001.         + It's possible to specify stream type. E.g. -map 0:a:2 creates an

  1002.           output stream from the third input audio stream.

  1003.         + Omitting the stream index now maps all the streams of the given type,

  1004.           not just the first. E.g. -map 0:s creates output streams for all the

  1005.           subtitle streams in the first input file.

  1006.         + Since -map can now match multiple streams, negative mappings were

  1007.           introduced. Negative mappings disable some streams from an already

  1008.           defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for

  1009.           all the stream in the first input file, except for the second audio

  1010.           stream'.

  1011.     * There is a new option -c (or -codec) for choosing the decoder/encoder to

  1012.       use, which makes it possible to precisely specify target stream(s) consistently with

  1013.       other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0

  1014.       libvorbis sets the codec for the first audio stream and -c copy copies all

  1015.       the streams without reencoding. Old -vcodec/-acodec/-scodec options are now

  1016.       aliases to -c:v/a/s

  1017.     * It is now possible to precisely specify which stream should an AVOption

  1018.       apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while

  1019.       -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k

  1020.       syntax is deprecated and will stop working soon.

  1021.     * -map_chapters now takes only an input file index and applies to the next

  1022.       output file. This is consistent with how all the other options work.

  1023.     * -map_metadata now takes only an input metadata specifier and applies to

  1024.       the next output file. Output metadata specifier is now part of the option

  1025.       name, similarly to the AVOptions/map/codec feature above.

  1026.     * -metadata can now be used to set metadata on streams and chapters, e.g.

  1027.       -metadata:s:1 language=eng sets the language of the first stream to 'eng'.

  1028.       This made -vlang/-alang/-slang options redundant, so they were removed.

  1029.     * -qscale option now uses stream specifiers and applies to all streams, not

  1030.       just video. I.e. plain -qscale number would now apply to all streams. To get

  1031.       the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale

  1032.       and -aq is now an alias for -q:a.

  1033.     * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which

  1034.       uses stream specifiers. Use -bsf:v/a/s instead of the old options.

  1035.     * -itsscale option now uses stream specifiers, so its argument is only the

  1036.       scale parameter.

  1037.     * -intra option was removed, use -g 0 for the same effect.

  1038.     * -psnr option was removed, use -flags +psnr for the same effect.

  1039.     * -vf option is now an alias to the new -filter option, which uses stream specifiers.

  1040.     * -vframes/-aframes/-dframes options are now aliases to the new -frames option.

  1041.     * -vtag/-atag/-stag options are now aliases to the new -tag option.
