Support for Arlo Wire-Free

[protonpopsicle]

Currently Arlo support is for Arlo-Q. I tested the Arlo Wire-Free camera and it does not playback in STAVPlay. Two issues: Arlo Wire-Free has no audio source--this case is not handled in STAVPlay. Additionally STAVPlay struggles with the video source.

ffprobe output:

Wire-Free: Video: h264 (Main), yuv420p, 640x352, 24 fps
Arlo-Q:    Video: h264 (Main), yuvj420p(pc, bt709), 1280x720 [SAR 1:1 DAR 16:9], 29.97 fps

The error that is raised when trying to playback the Wire-Free video only is:

./pepper_42/include/nacl_player/media_common.h:  MediaPlayerError_UnsupportedContainer = 8

@protonpopsicle - We could able to mock (yuv420p, 640x352, 15 fps) Video-only using gst-rtsp-server. And the current implementation handles well for video-only case with mock url. However we will confirm with Arlo Wire-free once we receive.
