335 - Flash Screen Video 2 decoder
336 - lavfi input device added
337 - added avconv, which is almost the same for now, except
338 for a few incompatible changes in the options, which will hopefully make them
339 easier to use. The changes are:
340 * The options placement is now strictly enforced! While in theory the
341 options for ffmpeg should be given in [input options] -i INPUT [output
342 options] OUTPUT order, in practice it was possible to give output options
343 before the -i and it mostly worked. Except when it didn't - the behavior was
344 a bit inconsistent. In avconv, it is not possible to mix input and output
345 options. All non-global options are reset after an input or output filename.
346 * All per-file options are now truly per-file - they apply only to the next
347 input or output file and specifying different values for different files
348 will now work properly (notably -ss and -t options).
349 * All per-stream options are now truly per-stream - it is possible to
350 specify which stream(s) should a given option apply to. See the Stream
351 specifiers section in the avconv manual for details.
352 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
353 sense that they're specified after the output filename instead of before,
354 like all other options. In avconv this irregularity is removed, all options
355 apply to the next input or output file.
356 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
357 irregular and highly confusing, they were also redundant. In avconv the -map
358 option will create new streams in the output file and map input streams to
359 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
360 each stream in the first input file.
361 * The -map option now has slightly different and more powerful syntax:
362 + Colons (':') are used to separate file index/stream type/stream index
363 instead of dots. Comma (',') is used to separate the sync stream instead
364 of colon.. This is done for consistency with other options.
365 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
366 output stream from the third input audio stream.
367 + Omitting the stream index now maps all the streams of the given type,
368 not just the first. E.g. -map 0:s creates output streams for all the
369 subtitle streams in the first input file.
370 + Since -map can now match multiple streams, negative mappings were
371 introduced. Negative mappings disable some streams from an already
372 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
373 all the stream in the first input file, except for the second audio
375 * There is a new option -c (or -codec) for choosing the decoder/encoder to
376 use, which allows to precisely specify target stream(s) consistently with
377 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
378 libvorbis sets the codec for the first audio stream and -c copy copies all
379 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
381 * It is now possible to precisely specify which stream should an AVOption
382 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
383 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
384 syntax is deprecated and will stop working soon.
385 * -map_chapters now takes only an input file index and applies to the next
386 output file. This is consistent with how all the other options work.
387 * -map_metadata now takes only an input metadata specifier and applies to
388 the next output file. Output metadata specifier is now part of the option
389 name, similarly to the AVOptions/map/codec feature above.
390 * -metadata can now be used to set metadata on streams and chapters, e.g.
391 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
392 This made -vlang/-alang/-slang options redundant, so they were removed.
393 * -qscale option now uses stream specifiers and applies to all streams, not
394 just video. I.e. plain -qscale number would now apply to all streams. To get
395 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
396 and -aq is now an alias for -q:a.
397 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
398 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
399 * -itsscale option now uses stream specifiers, so its argument is only the
401 * -intra option was removed, use -g 0 for the same effect.
402 * -psnr option was removed, use -flags +psnr for the same effect.
403 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
404 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
405 * -vtag/-atag/-stag options are now aliases to the new -tag option.
