  • I want to print HLS files using ffmpeg in aws lambda (python)

    14 avril 2021, par 최우선

    I implemented it through the link(https://aws.amazon.com/ko/blogs/media/processing-user-generated-content-using-aws-lambda-and-ffmpeg/) here, and it works well.

    


    s3_source_bucket = event['Records'][0]['s3']['bucket']['name']
s3_source_key = event['Records'][0]['s3']['object']['key']

s3_source_basename = os.path.splitext(os.path.basename(s3_source_key))[0]
s3_destination_filename = s3_source_basename + ".m3u8"

s3_client = boto3.client('s3')
s3_source_signed_url = s3_client.generate_presigned_url('get_object',
    Params={'Bucket': s3_source_bucket, 'Key': s3_source_key},
    ExpiresIn=SIGNED_URL_TIMEOUT)


ffmpeg_cmd = "/opt/bin/ffmpeg -i \"" + s3_source_signed_url + "\" -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls -"
command1 = shlex.split(ffmpeg_cmd)
p1 = subprocess.run(command1, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

resp = s3_client.put_object(Body=p1.stdout, Bucket=S3_DESTINATION_BUCKET, Key=s3_destination_filename)


    


    However, the actual output through ffmpeg is multiple files. For example test.m3u8, test0.ts, test1.ts .....

    


    But when I print p1.stdout, it looks like multiple files (test.m3u8,test0.ts....) are merged into one file.

    


    Is there a way to get the actual output multiple files (test.m3u8,test0.ts......) from p1.stdout ? Please help.

    


  • ffmpeg : convert a video by using another video's settings

    11 janvier 2015, par orcaman

    I have an mp4 file containing an H.264 video. This video has particular settings that I am not sure about, but I want to reproduce them on other videos that I encode (those other videos are already H.264 encoded, but they have different properties - bitrate, size, etc.)

    I know that ffprobe can be used to extract some information from the original video, and I guess that using this information I could try to reproduce the conversion settings required for use with other videos.

    Question is : do I have to do this manually, in the sense that I need to map the output of ffprobe to ffmpeg flags ? Is there a better way to do this, to make sure I don’t miss anything ?

    * commit '8f5de34c8fb18fa1416e77d2cb998773a49ddb3d' :
    
  vf_fade : Make sure to not miss the last lines of a frame
    

    This commit is a noop.
    

    [11:00:43] <jamrial> michaelni : what do you think of 8f5de34c8f ? does it apply to us ?
    
[11:01:50] <jamrial> our code started to deviate with your commit bca59d7745e, followed by the merge commit aa40df483b2
    
[11:33:51] <michaelni> jamrial, the fade commits are from 2013, but i think our fixes where complete and the problematic slice_h FFALIGN is also removed
