7 - Automatic thread count based on detection number of (available) CPU cores
13 - Flash Screen Video 2 decoder
14 - ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
15 - ffmpeg deprecated, added avconv, which is almost the same for now, except
16 for a few incompatible changes in the options, which will hopefully make them
17 easier to use. The changes are:
18 * The options placement is now strictly enforced! While in theory the
19 options for ffmpeg should be given in [input options] -i INPUT [output
20 options] OUTPUT order, in practice it was possible to give output options
21 before the -i and it mostly worked. Except when it didn't - the behavior was
22 a bit inconsistent. In avconv, it is not possible to mix input and output
23 options. All non-global options are reset after an input or output filename.
24 * All per-file options are now truly per-file - they apply only to the next
25 input or output file and specifying different values for different files
26 will now work properly (notably -ss and -t options).
27 * All per-stream options are now truly per-stream - it is possible to
28 specify which stream(s) should a given option apply to. See the Stream
29 specifiers section in the avconv manual for details.
30 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
31 sense that they're specified after the output filename instead of before,
32 like all other options. In avconv this irregularity is removed, all options
33 apply to the next input or output file.
34 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
35 irregular and highly confusing, they were also redundant. In avconv the -map
36 option will create new streams in the output file and map input streams to
37 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
38 each stream in the first input file.
39 * The -map option now has slightly different and more powerful syntax:
40 + Colons (':') are used to separate file index/stream type/stream index
41 instead of dots. Comma (',') is used to separate the sync stream instead
42 of colon.. This is done for consistency with other options.
43 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
44 output stream from the third input audio stream.
45 + Omitting the stream index now maps all the streams of the given type,
46 not just the first. E.g. -map 0:s creates output streams for all the
47 subtitle streams in the first input file.
48 + Since -map can now match multiple streams, negative mappings were
49 introduced. Negative mappings disable some streams from an already
50 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
51 all the stream in the first input file, except for the second audio
53 * There is a new option -c (or -codec) for choosing the decoder/encoder to
54 use, which allows to precisely specify target stream(s) consistently with
55 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
56 libvorbis sets the codec for the first audio stream and -c copy copies all
57 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
59 * It is now possible to precisely specify which stream should an AVOption
60 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
61 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
62 syntax is deprecated and will stop working soon.
63 * -map_chapters now takes only an input file index and applies to the next
64 output file. This is consistent with how all the other options work.
65 * -map_metadata now takes only an input metadata specifier and applies to
66 the next output file. Output metadata specifier is now part of the option
67 name, similarly to the AVOptions/map/codec feature above.
68 * -metadata can now be used to set metadata on streams and chapters, e.g.
69 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
70 This made -vlang/-alang/-slang options redundant, so they were removed.
71 * -qscale option now uses stream specifiers and applies to all streams, not
72 just video. I.e. plain -qscale number would now apply to all streams. To get
73 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
74 and -aq is now an alias for -q:a.
75 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
76 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
77 * -itsscale option now uses stream specifiers, so its argument is only the
79 * -intra option was removed, use -g 0 for the same effect.
80 * -psnr option was removed, use -flags +psnr for the same effect.
81 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
82 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
83 * -vtag/-atag/-stag options are now aliases to the new -tag option.

710 - added partial (frame only) MPEG-2 support
711 - changed the FOURCC code for H.263 to "U263" to be able to see the
712 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
713 this +codec ;) (JuanJo).
714 - Halfpel motion estimation after MB type selection (JuanJo)

718 - added pgmpipe I/O format (original patch from Martin Aumueller
719 <lists at reserv.at>, but changed completely since we use a format
720 instead of a protocol)
725 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
726 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
