ViQ videos play back using G.711, AAC-LD, or G.722, whichever the endpoint prefers. However, there is no video resolution scaling in MediaSense. A 320p video plays at 320p on every device, and a 1080p video plays at 1080p on every device. Most devices properly handle any necessary correction to the scaling, but the 8941, 8945, 9951, 9971 devices do not. Upload as 480p or less any video that is intended to play on a 8941, 8945, 9951, 9971 device. MediaSense does not support the G.711 A-Law codec for video playback.
