AK
285- ffmpeg deprecated, added avconv, which is almost the same for now, except
286for a few incompatible changes in the options, which will hopefully make them
287easier to use. The changes are:
c4302a39
AK
288 * The options placement is now strictly enforced! While in theory the
289 options for ffmpeg should be given in [input options] -i INPUT [output
290 options] OUTPUT order, in practice it was possible to give output options
291 before the -i and it mostly worked. Except when it didn't - the behavior was
292 a bit inconsistent. In avconv, it is not possible to mix input and output
293 options. All non-global options are reset after an input or output filename.
294 * All per-file options are now truly per-file - they apply only to the next
295 input or output file and specifying different values for different files
296 will now work properly (notably -ss and -t options).
297 * All per-stream options are now truly per-stream - it is possible to
298 specify which stream(s) should a given option apply to. See the Stream
299 specifiers section in the avconv manual for details.
300 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
301 sense that they're specified after the output filename instead of before,
302 like all other options. In avconv this irregularity is removed, all options
303 apply to the next input or output file.
304 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
305 irregular and highly confusing, they were also redundant. In avconv the -map
306 option will create new streams in the output file and map input streams to
307 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
308 each stream in the first input file.
309 * The -map option now has slightly different and more powerful syntax:
310 + Colons (':') are used to separate file index/stream type/stream index
311 instead of dots. Comma (',') is used to separate the sync stream instead
312 of colon.. This is done for consistency with other options.
313 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
314 output stream from the third input audio stream.
315 + Omitting the stream index now maps all the streams of the given type,
316 not just the first. E.g. -map 0:s creates output streams for all the
317 subtitle streams in the first input file.
318 + Since -map can now match multiple streams, negative mappings were
320d7693 319 introduced. Negative mappings disable some streams from an already
c4302a39
AK
320 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
321 all the stream in the first input file, except for the second audio
322 stream'.
323 * There is a new option -c (or -codec) for choosing the decoder/encoder to
324 use, which allows to precisely specify target stream(s) consistently with
325 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
326 libvorbis sets the codec for the first audio stream and -c copy copies all
327 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
328 aliases to -c:v/a/s
320d7693 329 * It is now possible to precisely specify which stream should an AVOption
c4302a39
AK
330 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
331 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
332 syntax is deprecated and will stop working soon.
320d7693
AK
333 * -map_chapters now takes only an input file index and applies to the next
334 output file. This is consistent with how all the other options work.
335 * -map_metadata now takes only an input metadata specifier and applies to
336 the next output file. Output metadata specifier is now part of the option
337 name, similarly to the AVOptions/map/codec feature above.
c4302a39
AK
338 * -metadata can now be used to set metadata on streams and chapters, e.g.
339 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
340 This made -vlang/-alang/-slang options redundant, so they were removed.
341 * -qscale option now uses stream specifiers and applies to all streams, not
342 just video. I.e. plain -qscale number would now apply to all streams. To get
343 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
344 and -aq is now an alias for -q:a.
345 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
346 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
347 * -itsscale option now uses stream specifiers, so its argument is only the
348 scale parameter.
349 * -intra option was removed, use -g 0 for the same effect.
350 * -psnr option was removed, use -flags +psnr for the same effect.
351 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
352 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
353 * -vtag/-atag/-stag options are now aliases to the new -tag option.
