+- ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
+- ffmpeg deprecated, 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.
