У меня проблема с выходным видео ffmpeg.
Я использую Raspberry Pi для подключения видео (поток с IP-камеры) и звука. Его работа нормально. Я хотел бы добавить к моему выходному видео еще одно видео со второй камерой (в левом верхнем углу).
Графика выглядит так:

, это мой код для ситуации с top:
/home/pi/FFmpeg/ffmpeg -y -thread_queue_size 512K \
-re -vsync 1 -rtsp_transport tcp -itsoffset 0 -use_wallclock_as_timestamps 1 \
-i "rtsp://admin:admin@172.16.7.7:554/cam/realmonitor?channel=1&subtype=0" \
-thread_queue_size 512K -i "rtsp://video:video@172.16.7.8:554/cam/realmonitor?channel=1&subtype=0" \
-filter_complex "[1]scale=iw/3:ih/3 [pip]; [0][pip] overlay=3:3" \
-ar 44100 -itsoffset 1.5 -ac 2 -f alsa -ac 2 -thread_queue_size 512K -i default -f h264 \
-c:a aac -ab 128k -g 50 -strict -2 -f flv rtmp://127.0.0.1/sesja/transmisja
Поток запущен, однако количество кадров в секунду составляет 4-5, скорость составляет 0,3, поэтому выходной поток не работают правильно.
Я прошу помощи в настройке, возможно, Raspberry не поддерживает это решение аппаратно.
