  • Videos written with moviepy on amazon aws S3 are empty

    10 avril 2019, par cellistigs

    I am working on processing a dataset of large videos ( 100 GB) for a collaborative project. To make it easier to share data and results, I am keeping all videos remotely on an amazon S3 bucket, and processing it by mounting the bucket on an EC2 instance.

    One of the processing steps I am trying to do involves cropping the videos, and rewriting them into smaller segments. I am doing this with moviepy, splitting the video with the subclip method and calling :

    subclip.write_videofile("PathtoS3Bucket"+VideoName.split('.')[0]+'part' +str(segment)+ '.mp4',codec = 'mpeg4',bitrate = "1500k",threads = 2)

    I found that when the videos are too large (parameters set as above) calls to this function will sometimes generate empty files in my S3 bucket ( 10% of the time). Does anyone have insight into features of moviepy/ffmpeg/S3 that would lead to this ?

  • How do I install ffmpeg on one EC2 Amazon Linux instance that can stream a mp4 ? [closed]

    12 septembre 2020, par starpebble

    Good day. How can I install ffmpeg on an EC2 amazon linux machine that can stream a mp4 ?

    


    The goal : an ffmpeg install on EC2 Amazon Linux that can stream one mp4 to one rtmps endpoint. Then, create an integration test suite with it.

    


    Is it just me or is ffmpeg a little crippled on EC2 Amazon Linux ?

    


    Example :

    


    ffmpeg -re -i input.mp4 -c:v libx264 -b:v 6000K -maxrate 6000K -pix_fmt yuv420p -s 1920x1080 -profile:v main -preset veryfast -g 120 -x264opts "nal-hrd=cbr:no-scenecut” -acodec aac -ab 160k -ar 44100 -f flv rtmps:///app/


    


    Linux OS :

    


    Linux version 4.14.193-113.317.amzn1.x86_64 (mockbuild@koji-pdx-corp-builder-60005) (gcc version 7.2.1 20170915 (Red Hat 7.2.1-2) (GCC)) #1 SMP Thu Sep 3 19:08:08 UTC 2020


    


    The stackoverflow answer to similar questions fail to install a ffmpeg that can stream.

    


    An installation script such as Install FFMPEG Library on EC2 Server fail this year.

    


    The static downloads referenced on John Van Sickle-FFmpeg Static Builds fail to stream to IVS. I tried the i686 release, my first guess for an x86_64 instance.

    


    The git source tree compiled binary fails to stream. Example : The tip of the tree isn't what I expected because the binary fails to recognize switches like -preset.

    


    I'd love to be able to explain streaming to anyone. Thanks.
