raspivid의 제한(?) 인지 1920*1080이 최대라
-md 설정을 이용한 최대 해상도인 2592*1944(5M)는 스트리밍이 불가능...
그래도 확실히 1920보다는 해상도가 오르니 나은건가?
요건 안되고
$ raspivid -o - -t 0 -n -md 2 -w 2592 -h 1944 | cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264
얘는 되고..
$ raspivid -o - -t 0 -n -md 2 | cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264
RASPIVID -mode, -md Sets a specified sensor mode, disabling the automatic selection. Possible values are : Mode Size Aspect Ratio Frame rates FOV Binning 0 automatic selection 1 1920x1080 16:9 1-30fps Partial None 2 2592x1944 4:3 1-15fps Full None --width, -w Set image width <size> Width of resulting video. This should be between 64 and 1920. --height, -h Set image height <size> Height of resulting video. This should be between 64 and 1080. |

캡쳐 해보니.. 화각이랑 해상도가 달라지긴 하네..
2M (1920x1080)
5M(2592x1944)

음... 왜 안되지 ... ㅠㅠ

음.. 비디오 코어 자체가 fullHD 인코딩이라.. 그 이상의 해상도는 무리인건가?
rpicam v2 에서도 그럼 8M 로 받아와도 2M로 밖에 전송이 불가능할지도?
