FFmpeg is a multiplatform, open-source library to record, convert and stream video and audio files. Created in 2000, it is a powerful command-line tool that runs on Linux, Windows and Mac operating systems. FFmpeg is currently used by many websites and programs, including YouTube and VLC Media Player, and is published under the GNU Lesser. A complete, cross-platform solution to record, convert and stream audio and video. Converting video and audio has never been so easy. $ ffmpeg -i input.mp4 output.avi.

FFmpeg GUIs

A GUI is a graphical user interface that makes it easy for a user to work with FFmpeg. Since FFmpeg is open-source, various developers have built software to utilize it with simple GUIs.

Benefits to Using a GUI

Since FFmpeg is used through a command line interface (CLI), there is a relatively steep learning curve for users who are unfamiliar with this type of interface. Using a CLI requires that the user understand how to write commands with the proper language and syntax. Software that provides a GUI makes using FFmpeg as easy as clicking a few buttons and setting a few parameters.

Examples:

  • QWinFF: http://qwinff.github.io/
  • AVANTI - FFmpeg/AviSynth GUI: http://avanti.arrozcru.com/
  • WinFF: http://winff.org/html_new/
  • FFmpegx (mac): http://www.FFmpegx.com/
  • Handbrake: http://handbrake.fr/
  • Mpeg streamclip: http://www.squared5.com/
  • FFmpegYAG (Windows / Linux): https://sourceforge.net/projects/ffmpegyag/

Limitations to Using a GUI

Using a GUI allows the user to jump right into FFmpeg, but it obfuscates what’s happening “under the hood.” Some users may want to know the FFmpeg command generated by using the GUI, and that is not always accessible. Also, GUIs are not always up to date with the latest version of FFmpeg.

I know I could (may be should) have posted this in the Mac section, but I decided against it since it's partly a general question.
background:
StabilizerI'm trying to get hardware encoding working on my mac which works through the use of the videotoolbox API, which ffmpeg/libav supports (https://github.com/FFmpeg/FFmpeg/tree/master/libavcodec)
I did a blind test using:
and the encoding worked fine.
Problem is: What options are available through ffmpeg in regard to videotoolbox.
Here's what I know:
  • '-vcodec X': allows to select the output type (h264_videotoolbox for H.264, hevc_videotoolbox for H.265)
  • for HEVC:
  • for AVC:
I also know that I can set a target bitrate using '-c:v X', but what other options are there? Can I set an aspect ratio? A max bitrate? ..
What are the options that are available to both encoders?
  • '-c:v X' to set the bitrate
  • '-g X' to set the gop size, '-g 1' will be I-Frame only encoding.
  • . help

Has anyone some more experience with this and can lend a helping hand?
Since I normally don't use ffmpeg for encoding video I'm a bit at a loss here and would be happy to get some help.
