• 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.

  


• Add watermark-overlay with -filter_complex to multiple outputs (dash)

  13 juillet 2020, par Werner

  I'm creating a set of files for DASH (without audio) with :

  


  ffmpeg -i "input.mov"
 -y
 -keyint_min 100 -g 100
 -sc_threshold 0
 -c:v libx264
 -pix_fmt yuv420p
 -map v:0 -s:0 320x180 -b:v:0 681.125k -maxrate:0 681.125k -bufsize:0 340.5625k
 -map v:0 -s:1 640x360 -b:v:1 2724.5k -maxrate:1 2724.5k -bufsize:1 1362.25k
 -map v:0 -s:2 1280x720 -b:v:2 5449k -maxrate:2 5449k -bufsize:2 2724.5k
 -map v:0 -s:3 1920x1080 -b:v:3 10898k -maxrate:3 10898k -bufsize:3 5449k
 -init_seg_name "myname_$RepresentationID$.$ext$"
 -media_seg_name "myname_$RepresentationID$-$Number%05d$.$ext$"
 -use_template 1 -use_timeline 1
 -seg_duration 4 -adaptation_sets "id=0,streams=v"
 -f dash "myname.mpd"


  


  Now I want to add a watermark. How is it done ? I tried something like :

  


  ffmpeg -i "input.mov"
 -y
 -i "watermark.png" // Added
 -filter_complex "overlay=24:960" // Added
 -keyint_min 100 -g 100
 -sc_threshold 0
 -c:v libx264
 -pix_fmt yuv420p
 -map v:0 -s:0 320x180 -b:v:0 681.125k -maxrate:0 681.125k -bufsize:0 340.5625k
 -map v:0 -s:1 640x360 -b:v:1 2724.5k -maxrate:1 2724.5k -bufsize:1 1362.25k
 -map v:0 -s:2 1280x720 -b:v:2 5449k -maxrate:2 5449k -bufsize:2 2724.5k
 -map v:0 -s:3 1920x1080 -b:v:3 10898k -maxrate:3 10898k -bufsize:3 5449k
 -init_seg_name "myname_$RepresentationID$.$ext$"
 -media_seg_name "myname_$RepresentationID$-$Number%05d$.$ext$"
 -use_template 1 -use_timeline 1
 -seg_duration 4 -adaptation_sets "id=0,streams=v"
 -f dash "myname.mpd"


  


  But this results in only getting the 180p-Version of the video. How can I still get all versions of the video with the overlay ?

  


  Added :
I tried as well :

  


  ffmpeg -i "input.mov"
 -y
 -i "watermark.png"
 -filter_complex "[0:v][1:v]overlay=24:960[out0][out1][out2][out3]"
 -keyint_min 100 -g 100
 -sc_threshold 0
 -c:v libx264
 -pix_fmt yuv420p
 -map "[out0]" -s:0 320x180 -b:v:0 681.125k -maxrate:0 681.125k -bufsize:0 340.5625k
 -map "[out1]" -s:1 640x360 -b:v:1 2724.5k -maxrate:1 2724.5k -bufsize:1 1362.25k
 -map "[out2]" -s:2 1280x720 -b:v:2 5449k -maxrate:2 5449k -bufsize:2 2724.5k
 -map "[out3]" -s:3 1920x1080 -b:v:3 10898k -maxrate:3 10898k -bufsize:3 5449k
 -init_seg_name "myname_$RepresentationID$.$ext$"
 -media_seg_name "myname_$RepresentationID$-$Number%05d$.$ext$"
 -use_template 1 -use_timeline 1
 -seg_duration 4 -adaptation_sets "id=0,streams=v"
 -f dash "myname.mpd"


  


  which results in the error :
No output pad can be associated to link label 'out1'.

  


• FFMPEG - Merge 2 Files (video_video), with TC and watermark

  11 juin 2020, par Felipe Silva

  I need to merge two video files, add a watermaker and a timecode burned in the video.

  



  I see this (by @llogan :)

  



  ffmpeg -i video.mp4 -i audio.mp3 -i watermark.png -filter_complex "[0:v:0]drawtext=fontfile=/usr/share/fonts/TTF/DejaVuSansMono.ttf:timecode='01\:23\:45\:00':r=25:x=(w-text_w)/2:y=h-text_h-20:fontsize=20:fontcolor=white:box=1:boxborderw=4:boxcolor=black[bg];[1][bg]overlay=W-w-10:H-h-12:format=auto[v]" -map "[v]" -map 1:a -shortest output.mp4


  



  But I can't apply for two videos, because of the map. Can someone help me, please ? My last attempt was :

  



  ffmpeg -i [video1] -i [video2] -i [image-overlay] -filter_complex "[0:v:0]drawtext=fontfile=/Windows/Fonts/arial.ttf: timecode='00\:00\:00\:00': r=25: x=(w-tw)/2: y=h-(2*lh): fontcolor=0xccFFFF@1: fontsize=85: box=1: boxcolor=0x000000@0.2[bg];concat=n=2:v=1:a=1[vv][a];[vv][2:v]overlay=0:0[v];[vv][bg]overlay=0:0" -map "[v]" -map "[a]" -c:v libx264 -b 2000k -preset fast -c:a aac [output file]
