  • Stream ffmpeg transcoding result to S3

    7 juin 2019, par mabead

    I want to transcode a large file using FFMPEG and store the result directly on AWS S3. This will be done inside of an AWS Lambda that has limited tmp space so I can’t store the transcoding result locally and then upload it to S3 in a second step. I won’t have enough tmp space. I therefore want to store the FFMPEG output directly on S3.

    I therefore created a S3 pre-signed url that allows ’PUT’ :

    var outputPath = s3Client.GetPreSignedURL(new Amazon.S3.Model.GetPreSignedUrlRequest
    {
       BucketName = "my-bucket",
       Expires = DateTime.UtcNow.AddMinutes(5),
       Key = "output.mp3",
       Verb = HttpVerb.PUT,
    });

    I then called ffmpeg with the resulting pre-signed url :

    ffmpeg -i C:\input.wav -y -vn -ar 44100 -ac 2 -ab 192k -f mp3 https://my-bucket.s3.amazonaws.com/output.mp3?AWSAccessKeyId=AKIAJDSGJWM63VQEXHIQ&Expires=1550427237&Signature=%2BE8Wc%2F%2FQYrvGxzc%2FgXnsvauKnac%3D

    FFMPEG returns an exit code of 1 with the following output :

    As you can see, I have a URL read error. This is a little surprising to me since I want to output to this url and not read it.

    Anybody know how I can store directly my FFMPEG output directly to S3 without having to store it locally first ?

    Edit 1
    I then tried to use the -method PUT parameter and use http instead of https to remove TLS from the equation. Here’s the output that I got when running ffmpeg with the -v trace option.

  • Getting small file size from ffmpeg [duplicate]

    20 février 2020, par sukach

    I am not an ffmpeg expert. I am trying to get some movies converted to a smaller DIVX file for a cheap portable DVD player for a family trip. The movies are for my kids so I’m not too concerned about quality.

    The DVD player is a 10.1", 1024x600 screen. It says it supports DIVX/MPEG2 files. It took me a lot of experimentation to get the right ffmpeg settings to even get it to work, but I found another answer that provided a very complex set of parameters that ultimately worked.

    I have converted about 20 movies with this setting and every one results in a file size of 1.1GB. I have tried different file sizes and crf settings and it is the same every time.

    Here is an example. First, the original file :

    Same file size but lower resolution.

    Any ideas on what the best settings to achieve my goal ?

  • Getting green screen in ffplay : Streaming desktop (DirectX surface) as H264 video over RTP stream using Live555

    7 novembre 2019, par Ram

    I’m trying to stream the desktop(DirectX surface in NV12 format) as H264 video over RTP stream using Live555 & Windows media foundation’s hardware encoder on Windows10, and expecting it to be rendered by ffplay (ffmpeg 4.2). But only getting a green screen like below,

    I referred MFWebCamToRTP mediafoundation-sample & Encoding DirectX surface using hardware MFT for implementing live555’s FramedSource and changing the input source to DirectX surface instead of webCam.

    I don’t know what am I missing, I have been trying to fix this for almost a week without any progress, and tried almost everything I could. Also, the online resources for encoding a DirectX surface as video are very limited.

    Any help would be appreciated.
