hi,我目前在抽取视频帧的脚本上遇到了些问题，希望能占用您几分钟 我的运行指令如下 python ./tools/extract_frames.py --source_dir ./tiny-Kinetics-400 --target_dir ./tiny-Kinetics-400_30fps_frames 并且我的数据集摆放如下图 而chans产生的结果则是全部报decode filed，如下图 Current class inx: 0 Video ./tiny-Kinetics-400/train_256/abseiling decode failed.

可以检查一下ffmpeg是否可以正常使用

[YancyGuo]

ffmpeg检测输出是没有问题的，后续用mmaction的脚本抽成功了，十分感谢您提供的数据集。

[jiajiajun]

您好，我也跟您一样decode失败了，请问您是用的mmaction里的哪个脚本解决的呢？多谢！

[YancyGuo]

传送门，然后具体的抽帧处理在官方手册——dataset preparation

传送门，然后具体的抽帧处理在官方手册——dataset preparation 已找到并解决，非常感谢！！

我一开始用cmd没有切换当前目录也遇到了这个问题，后续使用pycharm terminal成功运行。。小白也不懂怎么回事，希望给后来人一点经验。
