    Hello MIE team!
    First of all, Thank you for this really interesting and well-documented solution

    Thank you! Would you happen to know if I can safely uncomment parts of the CloudFormation yaml that relate to TranscribeWorkflow? From what I understood the Rekognition workflow does transcribing too, so it was a bit redundant. But if I did not need Rekognition, can I simply substitute it with TranscribeWorkflow by uncommenting it? Would it break compatibility with the Demo App?
    Ian Downard
    @iandow
    The demo app does not use the transcribeworkflow so you can remove it. Don’t remove the recognition workflow though because the demo app does use that one.

    @antonostrovsky
    Thank you for clarifying!

    I have just launched a test stack, and the Web-app can't display the video in the player. I have made this particular file public and I can access it if I follow a URL without the additional GET parameters like X-Amz-Algorithm

    But the Web-app attempts to access the media with credentials and security tokens within the GET request, which results in <Code>SignatureDoesNotMatch</Code>

    <Message>
    The request signature we calculated does not match the signature you provided. Check your key and signing method.

    @antonostrovsky I think you’re getting a CORS error. We see this sometimes, but it goes away within a few hours. Not sure what’s causing that, yet. What region are you in?
    Anton
    @antonostrovsky
    This is exactly it! It goes away in an hour or so. I am using region eu-west-2
    Ian Downard
    @iandow
    I’ve also seen it happen in eu-west-1. I have not seen it in the US regions yet.
    Anton
    @antonostrovsky
    OK, thank you for the information.

    You’re welcome. Anytime!

    I have a question about FaceSearch. I have successfully added some faces to a Rekognition collection, and confirmed that they were present:
    Faces in collection "people"
    {'FaceId': '1f5f7d4b-d82c-4499-9959-e078b8a0300b', 'BoundingBox': {'Width': 0.5046759843826294, 'Height': 0.59968101978302, 'Left': 0.20208899676799774, 'Top': 0.16646400094032288}, 'ImageId': '9c8e829e-25fe-37c7-a037-b33489de2ead', 'ExternalImageId': 'Matthew', 'Confidence': 100.0}
    {'FaceId': '22152d88-020e-44fc-b0a1-ee01ecb67fb3', 'BoundingBox': {'Width': 0.6467159986495972, 'Height': 0.6781880259513855, 'Left': 0.10873699933290482, 'Top': 0.2798289954662323}, 'ImageId': '3aecbfd0-31fd-3d29-a1a1-05bbeebd93fe', 'ExternalImageId': 'Kelz', 'Confidence': 99.99970245361328}
    A media file containing the faces above has been uploaded, and yet I can't see any matches at all in ML Vision -> Faces output. Is that where I should expect to see matches? And what would be the best way to troubleshoot the process?
    Ian Downard
    @iandow
    Double check that you created your face collection in the same region as where you deployed MIE.
    e.g. aws rekognition list-faces --collection-id family_faces --region us-east-2, where us-east-2 is the region where you deployed MIE.
    Anton
    @antonostrovsky
    Yes, all listed
    aws rekognition list-faces --collection-id people --region eu-west-2
    {
    "Faces": [
    {
    "FaceId": "1f5f7d4b-d82c-4499-9959-e078b8a0300b",
    "BoundingBox": {
    "Width": 0.5046759843826294,
    "Height": 0.59968101978302,
    "Left": 0.20208899676799774,
    "Top": 0.16646400094032288
    },
    "ImageId": "9c8e829e-25fe-37c7-a037-b33489de2ead",
    "ExternalImageId": "Matthew",
    "Confidence": 100.0
    },

    Oh, I see what’s happening. We haven’t surfaced “face search” (i.e. show me faces in my collection) results in the GUI yet.
    The GUI only shows "face detection” (i.e. show me all the faces) results.
    Ian Downard
    @iandow
    I'm going to remove face search from the workflow config for now, until I get a chance to surface those results in the GUI.
    Anton
    @antonostrovsky
    Thank you for looking into this. This is useful feedback, as I could try and get to these values from the local instance of the webapp. It looks like the results of faceSearch are in the ElasticSearch, is that correct?
    Ian Downard
    @iandow
    Yes, that’s correct.

    Hey! I have a use case which involves extracting frames by specifying timestamps to a video. Is there a way to do that using MIE?
    Ian Downard
    @iandow
    @rajesh1993 Yes, you can do that. First you would want to write an AWS Lambda function which extracts frames based on an input timestamp. Then you would use MIE to define a workflow which calls that function. Are you planning to use ffmpeg?
    Rajesh.M
    @rajesh1993
    Thanks Ian. I was looking for libraries in Python to do the same. I was not aware of ffmpeg. Would you recommend it over openCV (a simple Google search for a Pythonic way gave me this)?
    Ian Downard
    @iandow
    OpenCV is fine. You might also be able to use the thumbnail feature for AWS Mediaconvert to do the same. The disadvantage of using opencv is (I think) you’ll need to download the entire media file to /tmp in the lambda runtime environment in order to process it. However Mediaconvert could process it directly from s3, which would have no limit on file size.
