onPreviewFrame not getting called on start of recording



I want to get the preview frames during video recording. But when i start recording i am not getting onPreviewFrame callback. Any suggestions?



Isn’t onPreviewFrame an Android thing? You might have to be clearer about what software you are running (in fact perhaps you mention what hardware you are running too). AFAIK there isn’t really any Android release for Dragonboard 820C so the help on this forum could be rather limited.
