Hi,<br>
<br>
This sounds like <a href="https://gitlab.freedesktop.org/gstreamer/cerbero/-/merge_requests/655" target="_blank">https://gitlab.freedesktop.org/gstreamer/cerbero/-/merge_requests/655</a>
which is an issue with newer versions of setuptools.<br>
<br>
Cheers<br>

<div>This is probably because the value of the variable named

<div>I guess this value is fetched from

<div>Hi,</div>

<div>Your best bet for decoding AAC / AC3 on UWP is
described in this issue: <a href="https://gitlab.freedesktop.org/gstreamer/cerbero/-/issues/286" target="_blank">https://gitlab.freedesktop.org/gstreamer/cerbero/-/issues/286</a></div>
<div><br>
</div>
<div>Basically, the FFmpeg recipe doesn't use the Meson port
yet because it's a lot of work to test it on all platforms
supported by gstreamer. Need to ensure that the same code
is built on all platforms with basically the same flags
(and the correct optimizations). There wasn't enough time
to get that done for the 1.18 release.</div>

<div>Cheers,</div>

<div>Hi,</div>
<div><br>
</div>
<div>while I managed to play MP4 and TS video with a
modified UWP sample app, I haven't managed to play
the audio contained in these video files.</div>
<div><br>
</div>
<div>It seems that the required decoders are missing
from the GStreamer UWP release 1.18.0 release
(e.g. avdec_aac and avdec_ac3). Are there any
alternatives in the UWP release?</div>
