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