Determining playable media formats in qtmultimedia

[janorcutt]

Hi all,
I would like to write a function to determine which media formats can be played.
I thought about using QMediaPlayer::supportedMimeTypes, however the docs say this method is depreciated.
Is there any other way in qt or would i have to dig into kde frameworks/Windows Media apis for this.

Thanks in advance

Looks like this was deprecated because it can depend on the output device.

See QAudioDeviceInfo::availableDevice() and QAudioDeviceInfo::supportedCodecs().

Haven't checked if there are similar classes for Video or how they are called.

P.S.: in lots of cases it can be helpful to check how a deprecated function is implemented. Often this gives hints on alternatives.
Doesn't fully help here since apparently the current implementation depends on non-public API

and

Thanks for the reply.
QAudioDeviceInfo::supportedCodecs() returns only the pcm codec for some reason.
I could use QMimeDatabase but I'm unsure how well that works on Windows. Or macos for that matter.
Oh well more Google fu required

In any case the QMediaPlayer::supportedMimeTypes() will at least continue to work until Qt6, at which point there is likely documentation what to port this call to.
