4d58e4cb 210- ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
211- ffmpeg deprecated, added avconv, which is almost the same for now, except
212for a few incompatible changes in the options, which will hopefully make them
213easier to use. The changes are:
214 * The options placement is now strictly enforced! While in theory the
215 options for ffmpeg should be given in [input options] -i INPUT [output
216 options] OUTPUT order, in practice it was possible to give output options
217 before the -i and it mostly worked. Except when it didn't - the behavior was
218 a bit inconsistent. In avconv, it is not possible to mix input and output
219 options. All non-global options are reset after an input or output filename.
220 * All per-file options are now truly per-file - they apply only to the next
221 input or output file and specifying different values for different files
222 will now work properly (notably -ss and -t options).
223 * All per-stream options are now truly per-stream - it is possible to
224 specify which stream(s) should a given option apply to. See the Stream
225 specifiers section in the avconv manual for details.
226 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
227 sense that they're specified after the output filename instead of before,
228 like all other options. In avconv this irregularity is removed, all options
229 apply to the next input or output file.
230 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
231 irregular and highly confusing, they were also redundant. In avconv the -map
232 option will create new streams in the output file and map input streams to
233 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
234 each stream in the first input file.
235 * The -map option now has slightly different and more powerful syntax:
236 + Colons (':') are used to separate file index/stream type/stream index
237 instead of dots. Comma (',') is used to separate the sync stream instead
238 of colon.. This is done for consistency with other options.
239 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
240 output stream from the third input audio stream.
241 + Omitting the stream index now maps all the streams of the given type,
242 not just the first. E.g. -map 0:s creates output streams for all the
243 subtitle streams in the first input file.
244 + Since -map can now match multiple streams, negative mappings were
320d7693 245 introduced. Negative mappings disable some streams from an already
246 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
247 all the stream in the first input file, except for the second audio
248 stream'.
249 * There is a new option -c (or -codec) for choosing the decoder/encoder to
250 use, which allows to precisely specify target stream(s) consistently with
251 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
252 libvorbis sets the codec for the first audio stream and -c copy copies all
253 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
254 aliases to -c:v/a/s
320d7693 255 * It is now possible to precisely specify which stream should an AVOption
256 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
257 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
258 syntax is deprecated and will stop working soon.
259 * -map_chapters now takes only an input file index and applies to the next
260 output file. This is consistent with how all the other options work.
261 * -map_metadata now takes only an input metadata specifier and applies to
262 the next output file. Output metadata specifier is now part of the option
263 name, similarly to the AVOptions/map/codec feature above.
264 * -metadata can now be used to set metadata on streams and chapters, e.g.
265 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
266 This made -vlang/-alang/-slang options redundant, so they were removed.
267 * -qscale option now uses stream specifiers and applies to all streams, not
268 just video. I.e. plain -qscale number would now apply to all streams. To get
269 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
270 and -aq is now an alias for -q:a.
271 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
272 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
273 * -itsscale option now uses stream specifiers, so its argument is only the
274 scale parameter.
275 * -intra option was removed, use -g 0 for the same effect.
276 * -psnr option was removed, use -flags +psnr for the same effect.
277 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
278 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
279 * -vtag/-atag/-stag options are now aliases to the new -tag option.

56cc85a0 956 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 957- added multi live feed support in ffserver

959 external program which opens the .ffm url and writes it to another
960 ffserver)
961- added preliminary support for video stream parsing (WAV and AVI half
962 done). Added proper support for audio/video file conversion in
de6d9b64 963 ffmpeg.
