[GStreamer] media/video-volume.html broken after switching from cubic to linear scaling
https://bugs.webkit.org/show_bug.cgi?id=199505
Reviewed by Xabier Rodriguez-Calvar.
PulseAudio has a conversion process from volume's in
double-precision to uint32_t volumes. Depending on the environment
can introduce rounding errors. Be more lenient in our comparison
code.
* media/video-volume-expected.txt: Update baseline
* media/video-volume.html: Compare volume values within a
reasonable tolerance.
