Hi,

   I have a question regarding error code AUTH_FAIL during srtp_unprotect. I'm using gstreamer to send srtp audio packets and during transmission I do have a 'pause/resume functionality. 

   At pause the gst-launch cmd is terminated.

   At resume the gst-launch is restarted but by having a new SSRC (which is a mistake), while the srtp key remains the same and the sequence number is higher than the last one. I'm using:  AES_CM_128_HMAC_SHA1_32

   Since the SSRC has changed, should't the srtp library return an AUTH_FAIL ? It does not complain that the SSRC has changed and I do not understand why.

   Thank you.

BR,

Dan S.
