 |

Hi
I want to set the maximum possible number of consistent flags for the ffmpeg package.
How can this be done?
Is there any way to find out which use flags were used for the ffmpeg package in ubuntu? |

Thanks 
I would like to have the maximum set of functions. I'm tired of looking for the right flag every time and rebuilding the package.
Now I got the "Unknown encoder 'libfdk_aac'" error, as I understand it, the fdk flag is responsible for this library.
I would like to build it with the maximum number of flags so that such a problem does not happen again. |

The `equery` command, provided by app-portage/gentoolkit, can show you all available flags for a given package, together with their current status:
| Code: | $ equery u ffmpeg
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for media-video/ffmpeg-4.4.4-r10:

- - cpudetection : Enables runtime CPU detection (useful for bindist, compatibility on other CPUs)
+ + dav1d : Enables AV1 decoding via media-libs/dav1d.
- - debug : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see
https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
- - doc : Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
+ + encode : Add support for encoding of audio or video files
- - fdk : Use external fdk-aac library for AAC encoding
+ + fftools_aviocat : cat's a URL to another one, useful for dumping streams.
+ + fftools_cws2fws : converts cws files (Macromedia Flash, compressed) to fws ones (Macromedia Flash, uncompressed).
+ + fftools_ffescape : Escapes an input string, adopting the av_get_token() escaping logic.
+ + fftools_ffeval : A simple expression evalutor.
+ + fftools_ffhash : Computes a file's digest using libavutil algorithms.
+ + fftools_fourcc2pixfmt : Shows the relationships between rawvideo pixel formats and FourCC tags.
+ + fftools_graph2dot : A tool to convert a libavfilter graph to a dot file.
+ + fftools_ismindex : A tool for creating smooth streaming manifests.
+ + fftools_pktdumper : Dumps packets as demuxed by libavformat.
+ + fftools_qt-faststart : Rearranges a Quicktime file to facilitate network streaming.
+ + fftools_sidxindex : Write an MPD file for fragmented MP4 files with a sidx index at the start of the file.
+ + fftools_trasher : Writes burts of random data into a file. Great for testing error robustness/resilience/concealment.
- - flite : Adds a text-to-speech filter based on app-accessibility/flite.
+ + fontconfig : Support for configuring and customizing font access via media-libs/fontconfig
- - frei0r : Enable frei0r wrapping in libavfilter
- - fribidi : Enables fribidi support in the drawtext filter.
- - gcrypt : Enables gcrypt support: Needed for rtmp(t)e support if openssl, librtmp or gmp is not used.
- - glslang : Use dev-util/glslang to compile GLSL
- - gme : Enables support for media-libs/game-music-emu for playing various video game music formats.
- - gmp : Add support for dev-libs/gmp (GNU MP library)

+ + gpl : Build GPL code. Should be enabled unless you require LGPL binaries.
- - gsm : Add support for the gsm lossy speech compression codec
- - hardcoded-tables : Use pre-calculated tables rather than calculating them on the fly. It results in an increase of approximately 15% in
the size of libavcodec, the main library impacted by this change. It enables savings in table generation time, done
once at codec initialization, since by hardcoding the tables, they do not need to be computed at runtime. However,
the savings are often negligible (~100k cycles is a typical number) especially when amortized over the entire
encoding/decoding operation. Improvements are being made to the runtime initialization, and so over time, this
option will have an impact on fewer and fewer codecs.

I don't think a maximum set of flags will avoid problems. Some flags depend on others and some even require use flags on other packages. So there is no "set everything to on" and all is fine...

As Banana said, useflags are a gentoo/portage feature. But you can see what options were used during ffmpeg compilation just by invoking ffmpeg without any argument.
Here's the output on my gentoo, you can see what was enabled or disabled for my specific ffmpeg build

Hyper fast Audio and Video encoder
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...
Use -h to get full help or, even better, run 'man ffmpeg' |
So I guess using the ffmpeg command with a ubuntu liveCD/USB, you should be able to figure out what options were used for ffmpeg ubuntu build (but tbh many are not that useful, unless you spend a lot of time in video/audio editing or such)

Also there are things that can't be enabled at the same time. For example Systemd and OpenRC are incompatible. Possibly some FFMPEG flags can trigger these incompatibilities.
I know that it's a difficult thing to maintain but you must find a solution by yourself.
I personally spend my Fridays on that. Maintaining my machines. I see what's going on and tweak them. I check my "favorite" packages for changes and recompile them. If something goes wrong I'll have the weekend to solve it. |

Never had problems. Most of the flags you don't need. What do you mean by "for the right flag every time", don't you put them in an entry in package.use?
What's the output of
| Code: | | grep -r ffmpeg /etc/portage |
Best Regards,
Georgi |

eix ffmpeg will show you the potential and default use flags.
