Most of the issues brought up in that thread are not technically Flatpak limitations, nor are they handled any better by Snap (eg mentioned apps missing a Flatpak don’t offer a Snap either).
celluloid flatpak gave subtitle errors with various mkv & mp4 files. either no subtitles or subtitles out of sync.
I do not personally experience this, therefore I cannot comment on it.
clamav has no flatpak. clamtk flatpak will only scan files saved by the user & not the home folder or any other system folder.
I haven’t ever had a need for any antivirus on Linux, with that being said if you’re only interested in scanning files you could have just added root fs access to said Flatpak and let it access any directory there is.
It’s just a flatpak override away, but you could also use Flatseal to manage permissions via a gui interface.
epiphany flatpak freezes often & for various youtube videos there is no sound.
I don’t use Epiphany. Are you using the Flathub or Fedora Flatpak for it?
ffmpeg & ffmpegthumbnailer have no flatpaks.
You don’t need a separate Flatpak for ffmpeg, it’s an extension of the freedesktop Platform runtime.
Simply use it as
flatpak run --command=ffmpeg org.freedesktop.Platform, it’s probably already pulled in as a dependency by other major apps.
There’s currently no Flatpak for ffmpegthumbnailer. You should stick with toolbox unfortunately.
mediawriter, why go the way flathub way for just one app.
Cause Flathub is de facto accepted as the Flatpak repository and mostly every single other one is a huge meme, except for ones maintained by upstream projects like Gnome’s and KDE’s.
Fedora only has its own repo cause software shipped with it currently has to be built by Fedora itself, plus there’s currently no direct way to exclude proprietary software (which Fedora can’t provide), though there’s been talk about filters and whitelists being put in place so as for it to be included in the future.
If the problematic apps mentioned above are being pulled in from Fedora’s remote you should give the Flathub builds a try. I’m fairly sure you won’t come across the same issues.
samba has no flatpak.
thunderbird flatpak & transmission flatpak both have no audio alerts.
I never personally pay attention to audio alerts. Do libnotify notifiacations for them work as expected?
