hls视频切片，定义hls_segment_filename,执行出错

[feng99721480]

请教下大佬，下面ffmpet命令我在cmd里执行是没问题的，在android里执行就回调IFFmpegListener的onFinish，这是为什么？ ffmpeg命令的目的是把rtsp流切片到本地，每个ts以时间戳命名，谢大佬。 private String[] getCutCommand(String rtspAddress, String second, String m3u8Path) {

    //20201202-0000.ts
    //ffmpeg -re -i rtsp://192.168.10.13/RK_100000030.sdp -codec copy -f hls -hls_list_size 0 -hls_wrap 10 -hls_time 10
    // -use_localtime 1 -hls_flags second_level_segment_index -hls_segment_filename %Y%m%d-%%04d.ts output.m3u8

    RxFFmpegCommandList cmdlist = new RxFFmpegCommandList()；
    cmdlist.append("-re");
    cmdlist.append("-i");
    cmdlist.append(rtspAddress);
    cmdlist.append("-codec");
    cmdlist.append("copy");
    cmdlist.append("-f");
    cmdlist.append("hls");
    cmdlist.append("-hls_list_size");
    cmdlist.append("0");
    cmdlist.append("-hls_wrap");
    cmdlist.append("10");
    cmdlist.append("-hls_time");
    cmdlist.append(second);
    cmdlist.append("-use_localtime");
    cmdlist.append("1");
    cmdlist.append("-hls_flags");
    cmdlist.append("second_level_segment_index");
    cmdlist.append("-hls_segment_filename");
    cmdlist.append("%Y%m%d-%%04d.ts");
    cmdlist.append(m3u8Path);

    ULog.d(TAG, "getCutCommand === cmdlist.toString:" + cmdlist.toString());

    return cmdlist.build();
}
