• Using ffmpeg for stream encryption by srtp in windows

  11 avril 2015, par user3248865

  I have been trying to make encrypted stream via ffmpeg and I´ve found srtp support in this library (ffmpeg documentation). Unfortunately, it seems that encryption doesn´t work at all. I´m using the following command to send stream :

  ffmpeg -re -i "output.mpg" -vcodec libx264 -f flv "srtp://192.168.0.100:7777?srtp_out_suite=AES_CM_128_HMAC_SHA1_80&srtp_out_params=00108310518720928b30d38f41149351559761969b71d79f8218a39259a7"

  and this one for stream receiving :

  ffplay "srtp://192.168.0.100:7777?srtp_in_suite=AES_CM_128_HMAC_SHA1_80&srtp_in_params=00108310518720928b30d38f41149351559761969b71d79f8218a39259a7"

  They work good.
  But, If I change the command for ffplay to this one :

  ffplay udp://192.168.0.100:7777

  it works too and I can watch the video. So, it means that encryption for srtp doesn´t work ?

  1. Is the stream encryption by using ffmpeg possible (not only srtp) ?
  2. If so, What am I doing wrong ?

  Thanks in advance.

  An output from ffmpeg -re -i ... command is :

  Edit :

  I have tried the above ffmpeg command with srtp_out_suite=NmcxMmQ2ZjVnYjEyNmRmMTV2czY1YWR2ZjFhc2Rm, but udp stream is still playing well.
