It can also convert between arbitrary sample rates and resize video on the fly with a high quality polyphase filter. AVplay is a very simple and portable media player using the Libav libraries and the SDL library. avprobe gathers information from multimedia streams and prints it in human- and machine-readable fashion. avserver is a streaming server for both audio and video. Command line tools.

It seems that branch 12 will bot released before I am 6 feet under!
That sucks! LIBAV is not a good choice for developers who wants to be up-to-date!
Your overall better choice is FFMPEG!

Still no branch 12 to see on the horizon!
That makes me tired...

It still does not have proper support for Avisynth 2.6, is a shame.

Feb 29, 2016 Version: Libav OS: Windows 7 Ease of use: 5/10 Functionality: 5/10 Value for money: 5/10 Overall: 5/10

Simply annoying is the long time between major release versions. Version 12 is under development since more than a half year, but we still see no release version announced. I just complain about it because most open source software developer do not use nightly builds so new features not come to life in proper libav based softwsae tools while ffmpeg based tools have it included due to their faster integration to release versions & the shorter release cycles.
I do not say that ffmpeg is more better than libav or the other way around. I just say that great developments does not cone to life without a force to release it soon. Development in libav is great, but please let it out all the good work you did to can use all the good work in great tools such as VLC Player or Handbrake. If these tools would use ffmpeg libraries the missing features & format support would be already a part of it...

My hope for the future is to see libav & ffmpeg teams joined.

Nov 1, 2015 Version: 12 OS: Windows 7 64-bit Ease of use: 5/10 Functionality: 10/10 Value for money: 10/10 Overall: 5/10

Twelve years ago that Avisynth use, in ffmpeg I have no problems, in mencoder I have no problems, in libav:

"avconv version v12_dev0-1322-g4e17946, Copyright (c) 2000-2015 the Libav developers
built on May 24 2015 18:24:04 with gcc 4.8.3 (Gentoo 4.8.3 p1.1, pie-0.5.9)
C:\Program Files (x86)\LIBAV\usr\bin\LIBRA.avs: Invalid data found when processing input"

Please fix it.
Thank you.
