我也遇到了同样场景，经过尝试貌似解决了，目前没有遇到抛错了；首先得依赖完整包，然后构建命令： new RxFFmpegCommandList() .append("-ss") .append(CommUtils.videoTimeCut(start)) .append("-to") .append(CommUtils.videoTimeCut(end)) .append("-accurate_seek") .append("-i") .append(info.path) .append("-c:v") .append("libx264") .append("-avoid_negative_ts") .append("1") .append(file.getAbsolutePath())

获取裁剪时间：
public static String videoTimeCut(long time) { final int ms = (int) (time % 1000); final int t = (int) (time / 1000); final int s = t % 60; final int m = t / 60 % 60; final int h = t / 3600; return new Formatter(new StringBuilder(), Locale.getDefault()).format("%02d:%02d:%02d.%03d", h, m, s, ms).toString(); }
