<div dir="ltr">Hi all,<br>


        
        <span></span>
        
        


<p style="margin-bottom:0.2in;line-height:100%">Here I am trying
to <b>encrypt and decrypt</b> media file using "<b>aes-cbc openssl</b>"
in Gstreamer.</p>
<p style="margin-bottom:0in;line-height:100%">I followed below
link for Gst-crypto
library:<br><a href="https://developer.ridgerun.com/wiki/index.php?title=RidgeRun_gst-crypto_GStreamer_Plugin"><u>https://developer.ridgerun.com/wiki/index.php?title=RidgeRun_gst-crypto_GStreamer_Plugin</u></a></p>
<p style="margin-bottom:0in;line-height:100%"><br>
</p>
<p style="margin-bottom:0in;line-height:100%">But while doing
encryption I lose my metadata information. This given pipeline I
used,</p>
<p style="margin-bottom:0in;line-height:100%"><b>$gst-launch-1.0
filesrc location=</b><span style="font-weight:normal">1.mp4</span><b>
! crypto mode=enc ! filesink location=</b><span style="font-weight:normal">1_enc.mp4</span></p>
<p style="margin-bottom:0.2in;line-height:100%">so, here I am not
getting previous metadata information.</p>
<p style="margin-bottom:0.2in;line-height:100%"><b>$mediainfo
1_enc.mp4</b></p>
<p style="margin-bottom:0.2in;line-height:100%"><b>-</b><span style="font-weight:normal">not
getting any metadata information.</span></p>
<p style="margin-bottom:0in;line-height:100%">So can anyone
provide solution for getting metadata after encryption or</p>
<p style="margin-bottom:0in;line-height:100%">during encryption
process how to protect metdata?</p>
