video - What's the difference between libavcodec-ffmpeg-extra56 and libavcodec-ffmpeg56? Which should I install? - Ask Ubuntu


as title says - what's difference between libavcodec-ffmpeg-extra56 , libavcodec-ffmpeg56? should install?

i'm using kdenlive auditioning other non-linear video editors. matter of these packages installed, presumably 1 ffmpeg , 1 ubuntu bawdlerised version (or avconv now?)?

advice please?

edit, packages.ubuntu.com:

package libavcodec-ffmpeg-extra56

xenial (16.04lts) (libs): ffmpeg library **additional** de/encoders audio/video codecs [universe] 7:2.8.8-0ubuntu0.16.04.1 [security]: amd64 i386 7:2.8.6-1ubuntu2 [ports]: arm64 armhf powerpc ppc64el s390x

package libavcodec-ffmpeg56

xenial (16.04lts) (libs): ffmpeg library de/encoders audio/video codecs - runtime files [universe] 7:2.8.8-0ubuntu0.16.04.1 [security]: amd64 i386 7:2.8.6-1ubuntu2 [ports]: arm64 armhf powerpc ppc64el s390x

if @ files (plain, extra) difference appears file in /usr/share/lintian/overrides/. .so files identically named , versioned.

libavcodec-ffmpeg-extra56 adds additional, useless encoders:

  • libopencore_amrwb - adaptive multi-rate wide (amr-wb). outdated format used in old phones.
  • libopencore_amrnb - adaptive multi-rate narrowband (amr-nb). outdated format used in old phones.
  • libvo_aacenc - aac-lc audio encoder. this has been removed upstream in ffmpeg since it's crappy encoder , native ffmpeg aac encoder (-c:a aac) better.

so there no reason install particular package unless need encode amr. i've never had need so.

ubuntu no longer uses libav fork including avconv. use ffmpeg.
