映像伝送実験でH.264を使ったRTP通信したくなったのでGstreamerでやってみました．備忘録です．

環境
Ubuntu Linux 20.04
Roland UVC-01
受信側
gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,width=1280,height=720,framerate=30/1,format=YUY2 ! videoconvert ! video/x-raw,format=NV12 ! x264enc ! rtph264pay ! udpsink host=127.0.0.1 port=5005 sync=false
やっていることとしては，RAWで1280*720 30fpsを入力してx264encのソースとして対応してるNV12に変換したあとX264encに入れてrtph264pay udpsinkでrtp送信しています．
今回はHDMI入力した映像を出力したかったのでRolandのお高いまあまあ良いキャプチャボードを使っています．これなにが良いってRAW(YUV)で1080p60とか出力できるところなんですよね．Mjpegとかじゃないので実験や研究段階で非常に重宝します．
ちなみに，普通のUSBカメラだとMjpegで720p30などで出力されることが多く，RAWで出力しようとすると8fpsとか3fpsとかしか出力できないことが多いです(USB2.0はたった480Mbpsなので帯域的にも仕方ない)．手持ちのカメラがどんなものを出力できるのか調べる方法は余談で述べます．
Mjpegで入力したい場合は一度Jpeg DecoderでデコードしてRAWにしてから更にH264にエンコードする必要があるので注意です．当然ですがその分遅延も発生します．RAWで出力できるカメラがほしいんじゃ！って人は高いですがLogicoolのBRIO 4Kカメラ とかはおすすめです．もしくは今回のようにRAWで入力できるキャプチャボードから映像を入れるのも手です．
受信側
gst-launch-1.0 -v udpsrc port=5005 ! application/x-rtp,media=video,encoding-name=H264 ! queue ! rtph264depay ! avdec_h264 ! videoconvert ! autovideosink
言うことはないですが，そのまんまrtp受信してh264デコード，Autovidesinkで表示している感じです．
videoデバイスの出力形式を知る方法
例えばですが/dev/video0にカメラがつながっていればこのようにすると調べられます．この場合はC922 Pro Stream Webcamです．YUYV422だと800x448 30fpsに対応，1920*1080だと5fpsしかでないんですねー．公式にはFHDまでとされていますがセンサー自体は2304x1536まで出力できるようで，RAWであれば2304x1536 2fpsまで取れるみたいですよ．Mjpeg形式で出力するのであれば1080pでももちろん30fps出ます．
ここから下は手持ちのUSBビデオデバイスの出力をメモしておきます．
