Description of your issue, suggested solution and other information

When I use youtube-dl to download video from IQIYI, the program is downloading all format information first, which is totally meaningless and wasting time. Even when I specify the format I want. Eg., When I use -f h1 in the command, Youtube-dl will get through all possible format, h6 h5 h3 h2 h1, and each format has couple segments. This wastes my time, and if my internet connection is poor. I'll easily get timeout or fail to download the video I want.
Can you improve the code to let youtube-dl download the best quality format or download the format I required directly?

Since Iqiyi changed their codes and youtube-dl gets fixed in 2644e91, this problem is gone.
