java - FFMPEG profile-level-id 大小无效

Question

我正在尝试从 JVC KY-PZ 100 录制 RTSP 流.
因此，为此我使用带有一些参数的 ffmpeg，如分段、hls、ts、m3u8 等......
我总是收到错误The profile-level-id field size is invalid (41)和 Error parsing AU headers
这是 FFPROBE 的输出调试 RTSP

ffprobe -loglevel verbose  -i rtsp://jvc:0000@192.168.0.124:554/stream
