定番の $ gst-launch-1.0.exe videotestsrc ! autovideosink が失敗します。
Windows10に、GStreamerの1.24をインストール(フルインストールを選ぶこと)をしたのですが、定番の、
$ gst-launch-1.0.exe videotestsrc ! autovideosink

となります。別のWindows BOXでも、先日も経験して、青ざめていました。
結果として、
$ gst-launch-1.0 videotestsrc ! glimagesink
とすれば動きます。
autovideosinkが動かん、っていうのは、結局分かっていませんが、これは困りものです。
