How to retrieve metadata in AES-CBC-128bit Encryption

Deep Patel
Hi all,

Here I am trying to encrypt and decrypt media file using "aes-cbc openssl" in Gstreamer.

I followed below link for Gst-crypto library:
https://developer.ridgerun.com/wiki/index.php?title=RidgeRun_gst-crypto_GStreamer_Plugin


But while doing encryption I lose my metadata information. This given pipeline I used,

$gst-launch-1.0 filesrc location=1.mp4 ! crypto mode=enc ! filesink location=1_enc.mp4

so, here I am not getting previous metadata information.

$mediainfo 1_enc.mp4

-not getting any metadata information.

So can anyone provide solution for getting metadata after encryption or

during encryption process how to protect metdata?
