  • FFMPEG Encryption

    23 septembre 2015, par rickyma924

    I am doing a project with encrypting
    video and I have a few questions for the procedure.

    I used a command to transcode mp4 to HLS with a ts segment duration of 10 seconds.

    First, I need to encrypt those videos with a key from database. However,
    I have no idea for the encryption whether working with ffmpeg or not.

    Second, if the encryption can work without ffmpeg, so what should I do ? I have searched in google which includes something like openssl / aes but
    there is no a detailed step for me to follow, even the ffmpeg link :
    http://www.ffmpeg.org/ffmpeg-all.html#srtp

    Could anyone give me a hand, teaching me how to encrypt a video ? Thanks to you.

  • passing additional values to s3 event notification for lambda consumption

    8 septembre 2017, par user1790300

    I have to write code in react-native that allows a user to upload videos to amazon s3 to be transcoded for consumption by various devices. For the processing after the upload occurs ; I am reviewing two approaches :

    1) I can use Lambda with ffmpeg to handle the transcoding immediately after the uploading occurs (my fear here would be the amount of time required to transcode the videos and the effect on pricing if it takes a considerable amount of time).

    2) I can have s3 pass an sns message to a rest api after the created event occurs and the rest api generate a rabbitmq message that will be processed by worker that will perform the transcoding using ffmpeg.

    Option 1) seems to be the preferable option based on a completion time perspective. How concerned should I be with using 1) considering how long video transcoding might take as opposed to option 2) ?

    Also, regardless, I need a way to pass additional parameters to lambda or along the sns messaging that would allow me to somehow associate the user who uploaded the video with their account. Is there a way to pass additional text-based values to s3 to pass along to lambda or along sns when the upload completes, as a caveat I plan to upload the video directly to s3 using the rest layer(found this answer here : http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html#RESTObjectPUT-responses-examples) ?
