Is there any way to "decryption_key" argument

[silverman2012]

Hi,
I want to decrypta video file and use "-decryption_key" for ffplay, just like what I mention below:
ffplay 10M00S.mp4_enc.mp4 -decryption_key 76a6c65c5ea762046bd749a2e632ccbb

You can read about my idea here:

Hi silverman2012,
You could modify the native code as below and rebuild the dll for your customization.
In line 63 of ViveMediaDecoder/NativeCode/DecoderFFmpeg.cpp,
av_dict_set(&opts, "decryption_key", "76a6c65c5ea762046bd749a2e632ccbb", 0);
Thanks.
