avformat_open_input() error -22 Error setting option
avutil.av_log_set_level(avutil.AV_LOG_ERROR);
FFmpegLogCallback.set();
FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("rtsp://xxxxx");
grabber.setOption("use_wallclock_as_timestamps", "1");
grabber.setOption("rtsp_transport", "tcp");
grabber.setOption("rtsp_flags", "prefer_tcp");
grabber.start();
I used ffmpeg in JavaCV to pull rtsp streams, but there was an error like this
Error: [rtsp @ 0x7f2770145a60] Invalid option type.
Error: [rtsp @ 0x7f2770145a60] Error setting option use_wallclock_as_timestamps to value 1.

When I removed grabber.setOption("use_wallclock_as_timestamps", "1");, the following error occurred：
