• Streaming to facebook rtmps gives TLS connection error

  18 juin 2021, par jdramer

  I am trying to stream to Facebook with ffmpeg. As of late 2019 the connection requirement is rtmps. Using the stock Debian Buster ffmpeg the TLS connection fails.

• How to resize dimensions of video through ffmpeg-python ?

  25 janvier, par kunambi

  I'm trying to resize a video file which a user has uploaded to Django, by using ffmpeg-python. The documentation isn't very easy to understand, so I've tried to cobble this together from various sources.

  


  This method is run in a celery container, in order to not slow the experience for the user. The problem I'm facing is that I can't seem to resize the video file. I've tried two different approaches :

  


  from django.db import models
from io import BytesIO
from myapp.models import MediaModel


def resize_video(mypk: str) -> None:
    instance = MediaModel.objects.get(pk=mypk)
    media_instance: models.FileField = instance.media
    media_output = "test.mp4"
    buffer = BytesIO()

    for chunk in media_instance.chunks():
        buffer.write(chunk)

    stream_video = ffmpeg.input("pipe:").video.filter("scale", 720, -1)  # resize to 720px width
    stream_audio = ffmpeg.input("pipe:").audio
    process = (
        ffmpeg.output(stream_video, stream_audio, media_output, acodec="aac")
        .overwrite_output()
        .run_async(pipe_stdin=True, quiet=True)
    )
    buffer.seek(0)
    process_out, process_err = process.communicate(input=buffer.getbuffer())
    # (pdb) process_out
    # b''

    # attempting to use `.concat` instead
    process2 = (
        ffmpeg.concat(stream_video, stream_audio, v=1, a=1)
        .output(media_output)
        .overwrite_output()
        .run_async(pipe_stdin=True, quiet=True)
    )
    buffer.seek(0)
    process2_out, process2_err = process2.communicate(input=buffer.getbuffer())
    # (pdb) process2_out
    # b''


  


  As we can see, no matter which approach chosen, the output is an empty binary. The process_err and process2_err both generate the following message :
