 |

I have installed media-video/aegisub-3.4.0::gentoo but for some reason, "View > Options... > Advanced > Video > Video provider" list is empty. Likewise, "View > Options... > Advanced > Audio > Audio provider" list is empty too.
As a result, importing any audio from Audio > Open Audio File... or any video from Video > Open video fails with the following error:
| Quote: | None of the available audio providers recognised the selected file as containing audio data.
The following providers were tried:
PCM: RIFF PCM WAV audio provider: File is not a RIFF file
Wave64 audio provider: File is not a RIFF file |
| Quote: | Could not open /path/to/file.ext:
YUV4MPEG: video is not in a supported format. |
I don't have this issue with arch1t3cht fork (using Feature Release 12 AppImage). It allows me to choose between several "Video providers":
- FFmpegSource
- Avisynth
- BestSource
- VapourSynth
and I can import any audio/video file just fine. I can play these audio/video files on my system just fine as well.
I guess I should at least have "FFmpegSource" available since media-libs/ffmpegsource is a dependency (and was installed on my system when emerging media-video/aegisub::gentoo ):
| Code: | % qlist -Iv media-libs/ffmpegsource
media-libs/ffmpegsource-2.40-r2 |
emerge --info
| Code: | % equery u media-video/aegisub::gentoo
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for media-video/aegisub-3.4.0:
U I
+ + alsa : Add support for media-libs/alsa-lib (Advanced Linux Sound Architecture)
- - 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
+ + fftw : Use FFTW library for computing Fourier transforms
+ + lua_single_target_luajit : Build for LuaJIT only
- - openal : Add support for the Open Audio Library
- - portaudio : Add support for the crossplatform portaudio audio API
+ + pulseaudio : Add sound server support via media-libs/libpulse (may be PulseAudio or PipeWire)
+ + spell : Add dictionary support
- - test : Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled
independently)
+ + uchardet : Enable charset discovery via app-i18n/uchardet |
Any idea? |
