    url_file = r'/home/pi/Desktop/Instagram/urls.txt'
    # Get the link of the submission
    url = submission.url
    if url.endswith('gif'):
        bad_chars = ['"', '*', '?', ':', '<', '>', '|', '\\', '/', '.']
        for i in bad_chars:
            submission.title = submission.title.replace(i, '')
        count += 1
        print(url + ' ' + submission.title)
        urllib.request.urlretrieve(url, r'C:\Users\myalt\OneDrive\Desktop\TikTok twitch poster\Clips\\' + str(
            submission.title) + '.gif')
        print(str(f'downloaded {count}'))
    for file in os.listdir(r'C:\Users\myalt\OneDrive\Desktop\TikTok twitch poster\Clips\\'):
        clip = mp.VideoFileClip(rf"C:\Users\myalt\OneDrive\Desktop\TikTok twitch poster\Clips\{file}")
        clip.write_videofile(f"{submission.title}.mp4")

• Android - Best solution to convert recorded H.264 Main Profile videos to H.264 Baseline Profile

  19 février 2016, par Alireza

  I found MediaPlayer cannot play videos which are encoded by H.264 Main Profile and I tried ExoPlayer and Vitamio but none of them solved my problem. finally I found the best solution is converting videos to H.264 Baseline Profile. FFmpeg is almost 9MB and it’s so heavy for my project, so I don’t like to use it for converting videos to that profile by commands. My friend suggested converting videos on the server-side but we both know it has bad performance. What should I do ? What is the best solution to this problem ?

• How can I fix missing footage when I trim a video through ffmpeg ?

  18 juillet 2021, par LPMA

  I'm trying to remove commercials from an old PVR recording, and am extracting the main program by trimming/splitting the original file into separate parts :

  


  ffmpeg -i name.avi -ss 00:02:00 -to 00:08:20 -acodec copy -vcodec copy part01.avi
ffmpeg -i name.avi -ss 00:11:23 -to 00:22:03 -acodec copy -vcodec copy part02.avi
ffmpeg -i name.avi -ss 00:25:34 -to 00:36:37 -acodec copy -vcodec copy part03.avi
ffmpeg -i name.avi -ss 00:40:08 -to 00:52:11 -acodec copy -vcodec copy part04.avi
ffmpeg -i name.avi -ss 00:55:41 -to 01:52:53 -acodec copy -vcodec copy part05.avi


  


  For some reason, parts 3 and 5 are perfect, whereas parts 1, 2 and 4 each have about 9 seconds where the audio is playing against a "frozen" frame before the video part starts playing normally. The audio data seems to be intact (and cut at the designated place), but the video seems to be missing that data. I'm guessing it might have to do with reference frames ? Is there a quick way to fix/avoid the issue ? I would like to avoid data loss (through transcoding) as much as possible.
