  • Boto3 Video Upload 0 Bytes from Heroku

    14 juillet 2017, par genghiskhan

    I have a small Flask api that takes a video and an image, overlays the image on the video and uploads the result to Amazon S3. I am using ffmpeg to do the actual overlaying. Here is that code :

    command = "ffmpeg -i {0} -i {1} -filter_complex \"overlay=0:0\" {2}".format(background_name, overlay_name, output_name)
    
subprocess.getoutput(command)

    Then I simply upload it via Boto3 :

    s3.upload_file(output_name, VIDEO_BUCKET_NAME, output_name)

    This code works fine when I run on localhost ; however, when I test in while deployed to Heroku, it always uploads a file with 0 bytes. I suspect that it may be a problem with Heroku’s transient filesystem, but the file is being used immediately after it is created.

  • Execute ffmpeg in AWS ec2 instance windows

    15 janvier 2016, par Napster

    Im trying to execute ffmpeg command on amazon’s windows ec2 instance using elastic beanstalk.
    I intend to merge multiple videos into a single video using a .net application.

    I cant see the file being created in the folder, so cant confirm if ffmpeg is working. The merging is working perfectly on local deployment and i can view the merged video.
    I have configured my deployment for the required permission of file creation rights (.ebextensions) and it is working.

    Im not sure what i need to do to allow execution of ffmpeg command, and im stuck here. Ive been through the forum and found similar links related to linux but not windows.

    Being a newbie im really not sure how to proceed.
    Are there any permission/steps i need to perform to allow ffmpeg command to execute on ec2 instance. If any ? please share.

  • RTMP stream monitoring in python

    18 mars 2015, par lasgun

    I don’t have experience with python, but I found this online :
    https://gist.github.com/sinkers/d647a80fdb180b4cc3a6
    Assuming it works with the current version of ffmpeg (ffprobe), I tried to just modify the code a bit, so it doesn’t log in to Amazon SNS to send a message. Just simply opening an audio file when the stream goes down, with the following command (I found it on this site) would do just fine :

    os.system("start /sound/xyz.mp3")

    I tried to do this-and-that, but I can’t seem to succeed. I have 3.x installed.

    I know it’s probably silly, but do I need to enter the relative, or absolute file locations ? For ffprobe and the sound file, is it C :\... or what’s the correct format and path ?

    Any help to solve this would be greatly appreciated.
