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

e0db8cfb 981- added multi live feed support in ffserver
982- suppressed master feature from ffserver (it should be done with an
983 external program which opens the .ffm url and writes it to another
984 ffserver)
985- added preliminary support for video stream parsing (WAV and AVI half
986 done). Added proper support for audio/video file conversion in
de6d9b64 987 ffmpeg.
