  • Read a Bytes image from Amazon Kinesis output in python

    14 février 2020, par Varun_Rathinam

    I used imageio.get_reader(BytesIO(a),  'ffmpeg') to load a bytes image and save it as normal image.

    But the below error throws when I read the image using imageio.get_reader(BytesIO(a),  'ffmpeg')

    Traceback (most recent call last):

    The above approach to read a MKV bytes file was done based on this thread

    Or is there is any approach to parse and read the MKV bytes file.

  • Passing file name in youtube-dl post-process script without file extension suffix

    2 avril 2021, par Arete

    The documentation for youtube-dl says I can run a post-process command with the --exec option.

    &#xA;

    Using Windows, here is an example I have tried :

    &#xA;

    youtube-dl --exec "ffmpeg -i {} -ac 2 -c:a libfdk_aac -cutoff 20000 -afterburner 1 -vbr 0 {}.m4a" https://www.youtube.com/watch?v=sw9DlMNnpPM&#xA;

    &#xA;

    Note that {} passes the file name to the post-process command. For example filename.webm.

    &#xA;

    The problem is that {} includes the file extension.

    &#xA;

    How can I pass the file name to the post-process command without the file extension ?

    &#xA;

    For example, if I were to convert the video, I would rather avoid getting an output name like filename.webm.m4a. Needless to say, I would rather want filename.m4a.

    &#xA;
