• why ffmpeg only combines first 390 images when combining very large amount ( about 9k) images into video ?

  4 juillet 2021, par Siwei

  I have a VCD, and I split it into nearly 10,000 images, named like :

  


  $ ls tmp_enlarged_image_folder

vcd3_00000001.png
vcd3_00000002.png
vcd3_00000003.png
vcd3_00000004.png
...
vcd3_00089998.png
vcd3_00089999.png
vcd3_00090000.png


  


  and the following command doen't work for me :

  


  ffmpeg -loglevel trace -f image2 -r 25 -pattern_type sequence -i 'tmp_enlarged_image_folder/vcd3-%08d.png' -vcodec libx264 test.mp4



  


  and the detailed log shows as below :

• why it is taking a lot of time to convert image via HTTP to video in ffmpeg ?

  20 avril 2021, par al pacino

  Below is the ffmpeg i am using to convert images into videos but It is taking around 3 minutes to convert image to 5 second video.
If I run the command on Image present on a directory then it converts images to videos very swiftly.

  


  can anyone tell what I am doing wrong ?

• why it is taking a lot of time to convert image to video in ffmpeg ?

  20 avril 2021, par al pacino

  Below is a snippet of code i am using to convert images into videos but It is taking around 3 minutes to convert image to 5 second video.
If I run the command on Image present on a directory then it converts images to videos very swiftly. but i need to use try except to catch ConnectionError..
can anyone tell what I am doing wrong ?

  


  video = []
video_list = []
for video in videos:
    try:
        r = requests.get(video, stream=True)
        print(r.status_code)
        if not r.status_code == 200:
            message = "broken url process could not be completed"
            return message
        if r.status_code == 200:
            if video.endswith(".jpg") or video.endswith(".png") or video.endswith(".jpeg"):
                filename = str(uuid.uuid4())
                url2 = download_path + filename +".webm"
                #cmd = "ffmpeg -loop 1 -i '{}' -c:v libx264 -t 5 -pix_fmt yuv420p -vf scale={}:{} ".format(video, width, height)+ url2
                cmd = "ffmpeg -loop 1 -i '{}' -t 5 -vf scale={}:{} ".format(video, width, height) + url2
                os.system(cmd)
                path_remover(video)
                video_list.append(url2)
            else:
                video_list.append(video)
    except ConnectionError:
        for i in video_list:
            path_remover(i)
        message = "broken url process could not be completed"
        return message
