  1328. - BWF muxer
  1329. - Flash Screen Video 2 decoder
  1330. - lavfi input device added
  1331. - added avconv, which is almost the same for now, except
  1332. for a few incompatible changes in the options, which will hopefully make them
  1333. easier to use. The changes are:
  1334. * The options placement is now strictly enforced! While in theory the
  1335. options for ffmpeg should be given in [input options] -i INPUT [output
  1336. options] OUTPUT order, in practice it was possible to give output options
  1337. before the -i and it mostly worked. Except when it didn't - the behavior was
  1338. a bit inconsistent. In avconv, it is not possible to mix input and output
  1339. options. All non-global options are reset after an input or output filename.
  1340. * All per-file options are now truly per-file - they apply only to the next
  1341. input or output file and specifying different values for different files
  1342. will now work properly (notably -ss and -t options).
  1343. * All per-stream options are now truly per-stream - it is possible to
  1344. specify which stream(s) should a given option apply to. See the Stream
  1345. specifiers section in the avconv manual for details.
  1346. * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
  1347. sense that they're specified after the output filename instead of before,
  1348. like all other options. In avconv this irregularity is removed, all options
  1349. apply to the next input or output file.
  1350. * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
  1351. irregular and highly confusing, they were also redundant. In avconv the -map
  1352. option will create new streams in the output file and map input streams to
  1353. them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
  1354. each stream in the first input file.
  1355. * The -map option now has slightly different and more powerful syntax:
  1356. + Colons (':') are used to separate file index/stream type/stream index
  1357. instead of dots. Comma (',') is used to separate the sync stream instead
  1358. of colon.. This is done for consistency with other options.
  1359. + It's possible to specify stream type. E.g. -map 0:a:2 creates an
  1360. output stream from the third input audio stream.
  1361. + Omitting the stream index now maps all the streams of the given type,
  1362. not just the first. E.g. -map 0:s creates output streams for all the
  1363. subtitle streams in the first input file.
  1364. + Since -map can now match multiple streams, negative mappings were
  1365. introduced. Negative mappings disable some streams from an already
  1366. defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
  1367. all the stream in the first input file, except for the second audio
  1368. stream'.
  1369. * There is a new option -c (or -codec) for choosing the decoder/encoder to
  1370. use, which makes it possible to precisely specify target stream(s) consistently with
  1371. other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
  1372. libvorbis sets the codec for the first audio stream and -c copy copies all
  1373. the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
  1374. aliases to -c:v/a/s
  1375. * It is now possible to precisely specify which stream should an AVOption
  1376. apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
  1377. -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
  1378. syntax is deprecated and will stop working soon.
  1379. * -map_chapters now takes only an input file index and applies to the next
  1380. output file. This is consistent with how all the other options work.
  1381. * -map_metadata now takes only an input metadata specifier and applies to
  1382. the next output file. Output metadata specifier is now part of the option
  1383. name, similarly to the AVOptions/map/codec feature above.
  1384. * -metadata can now be used to set metadata on streams and chapters, e.g.
  1385. -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
  1386. This made -vlang/-alang/-slang options redundant, so they were removed.
  1387. * -qscale option now uses stream specifiers and applies to all streams, not
  1388. just video. I.e. plain -qscale number would now apply to all streams. To get
  1389. the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
  1390. and -aq is now an alias for -q:a.
  1391. * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
  1392. uses stream specifiers. Use -bsf:v/a/s instead of the old options.
  1393. * -itsscale option now uses stream specifiers, so its argument is only the
  1394. scale parameter.
  1395. * -intra option was removed, use -g 0 for the same effect.
  1396. * -psnr option was removed, use -flags +psnr for the same effect.
  1397. * -vf option is now an alias to the new -filter option, which uses stream specifiers.
  1398. * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
  1399. * -vtag/-atag/-stag options are now aliases to the new -tag option.
