Why the best preview's resolution is high? #49420
Description
I have a problem with quality of preview on Android devices, it's worse than pre-installed Camera app.
static Size computeBestPreviewSize(String cameraName, ResolutionPreset preset) {
if (preset.ordinal() > ResolutionPreset.high.ordinal()) {
preset = ResolutionPreset.high;
}
CamcorderProfile profile =
getBestAvailableCamcorderProfileForResolutionPreset(cameraName, preset);
return new Size(profile.videoFrameWidth, profile.videoFrameHeight);
}If I delete the row preset = ResolutionPreset.high;, then preview's quality seems good, but on some devices it affects to aspect ratio and preview is wrong scaled.
