• How to print the video meta output by the browser version of ffmpeg.wasm to the console of Google Chrome ?

  17 janvier 2021, par helloAl

  I would like to ask about how to use the browser version of ffmpeg.wasm.

  


  Through my investigation, I know that the following command can be used to output the video metadata to a file in the terminal of windows or mac.

  


  ffmpeg -i testvideo.mp4 -f ffmetadata testoutput.txt


  


  and then I can get this matadata like this :


  


  I want to parse the metadata of the video through the browser, and then print the metadata to the Google console (or output to a file). At present, I know that the browser version of ffmpeg.wasm can achieve this function, but I have looked at its examples, which does not involve this part of the content. (https://github.com/ffmpegwasm/ffmpeg.wasm/blob/master/examples/browser/image2video.html)

  


  But I want to print it to the console of Google Chrome through the browser version(usage:brower) of ffmpeg.wasm (https://github.com/ffmpegwasm/ffmpeg.wasm).
So I want to ask you how to achieve this, thank you.

• Add watermark in video with Google Cloud function python

  26 septembre 2020, par Dharmeshsharma

  I am adding watermark in uploaded video by http google cloud function but my code is return on ffmpeg non zero. my python code

  


  import os
from google.cloud import storage
from subprocess import check_output
from videoprops import get_video_properties


def hello_world(request):

client = storage.Client()
bucket = client.get_bucket('bucket_name')
request_json = request.get_json()
req_data = request.get_json()
name = req_data['file']
videofile_name = req_data['file_name']
os.makedirs('/tmp/'+os.path.dirname(name), exist_ok=True)
file_name = '/tmp/' + name
output_file_name = '/tmp/' + name.split('.')[0] + '_.'+name.split('.')[1]
print(output_file_name)
logo_path = '/temp/watermark.png'
logo_name = 'watermark.png'
print('logo found')

print(file_name)

try:
    os.remove(file_name)
except OSError:
    pass

try:
    os.remove(logo_path)
except OSError:
    pass

print("File has been removed")

# Downloading the video to the cloud functions
blob = bucket.get_blob(name)
blob.download_to_filename(file_name)

blob_logo = bucket.get_blob(logo_name)
blob_logo.download_to_filename(logo_path)

print("Video Downloaded")

props = get_video_properties(file_name)

if os.path.exists(file_name):
    print("NEW MP4 EXISTS")
    #   check_output('ffmpeg  -itsoffset -4  -i '+file_name+' -vcodec mjpeg -vframes 1 -an -f rawvideo -s '+str(props['width'])+'x'+str(props['height'])+' '+thumbnail_file_name, shell=True)
    #   thumbnail_blob = bucket.blob(os.path.dirname(name)+'/thumbnail.jpg')
    #   thumbnail_blob.upload_from_filename(thumbnail_file_name)
    # 19-7-2020
    check_output('ffmpeg  -i '+file_name+' -i '+logo_path +
                 ' -filter_complex overlay=10:10 -codec:a copy -preset ultrafast -async 1 '+output_file_name, shell=True)
    thumbnail_blob = bucket.blob(
        os.path.dirname(name) + '/'+videofile_name)
    thumbnail_blob.upload_from_filename(output_file_name)
    # -------------------------------------
else:
    print("MP4 not created")

print("uploaded")


  


  In this code accessing video add watermark also accessing from bucket and applying with ffmpeg and uploading.

  


  error is :-

  


  raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError : Command 'ffmpeg -i /tmp/Upload/Video/1060/ad69ec74-49db-4fdb-b118-d23b9468a7b8.mp4 -i /temp/watermark.png -filter_complex overlay=10:10 -codec:a copy -preset ultrafast -async 1 /tmp/Upload/Video/1060/ad69ec74-49db-4fdb-b118-d23b9468a7b8_.mp4' returned non-zero exit status 1.
