Ffmpeg shows the following streams available from the camera: Stream #0:0: Video: h264 (Main), yuv420p(progressive), 1920x1080, 12 fps, 12 tbr, 90k tbn, 24 tbc Stream #0:0: Video: h264 (Main), yuv420p(progressive), 640x352, 12 fps, 12 tbr, 90k tbn, 24 tbc Perhaps it's not even necessary to recode the stream?
