  My part of code for concatenation audio and video :

  


  def video_with_audio(number, filename, video):
        ms = datetime.today().strftime('%f') + '0000'
        ms = ms[:3]
        name = datetime.today().strftime('%Y:%m:%d_%H:%M:%S:')
        title_video = f'/home/pi/Desktop/VIDEOREG/{name}{ms}{number}.avi'
        print(title_video)
        os.system("ffmpeg -i " + video + " -vf setpts=PTS*2 " + title_video)
        ####################################################
        ms_1 = datetime.today().strftime('%f') + '0000'
        ms_1 = ms_1[:3]
        name_1 = datetime.today().strftime('%Y:%m:%d_%H:%M:%S:')
        title_video = f'/home/pi/Desktop/VIDEOREG/{name}{ms}{number}.avi'
        title_video_1 = f'/home/pi/Desktop/VIDEOREG/{name_1}{ms_1}{number}.avi'
        input_audio = ffmpeg.input(filename)
        input_video = ffmpeg.input(title_video)
        print(title_video_1)
        ffmpeg.concat(input_video, input_audio, v=1, a=1).output(title_video_1).run()


  


  There are slight delays during video recording, because I print information from sensors on video, can this affect the concatenation of video with audio ? (Saved video is accelerated ? that's why at the beginning I used slowing video down.)

  


• Error trying to install FFmpeg on Oracle Cloud VM Linux [closed]

  14 mai 2022, par lucasrvimieiro

  I'm trying to host a discord bot using Oracle Cloud but I need to install the FFmpeg extension for it to be able to play music. I have absolutely no experience with Linux at all but I was able to run the bot normally after a few tutorials. Everything is working fine except for the FFmpeg installation.

  


  I already tried following these guides :
https://computingforgeeks.com/how-to-install-ffmpeg-on-centos-rhel-8/
https://techviewleo.com/install-ffmpeg-on-rocky-almalinux-oracle-linux/

  


  However I keep getting the error :

  


  


  Errors during downloading metadata for repository 'nux-dextop' :

  


  

  • Status code : 404 for http://mirrors.coreix.net/li.nux.ro/nux/dextop/el7/aarch64/repodata/repomd.xml
(IP : xx.xx.xxx.xx)

  


  • Status code : 404 for http://li.nux.ro/download/nux/dextop/el7/aarch64/repodata/repomd.xml
(IP : xxx.xx.xx.xxx) Error : Failed to download metadata for repo
'nux-dextop' : Cannot download repomd.xml : Cannot download
repodata/repomd.xml : All mirrors were tried

  


  


  


  when executing :

  


  sudo dnf -y install ffmpeg


  


  I cannot find any solutions online. Is it even possible to install FFmpeg there ? The VM is running Oracle-Linux-8.5-aarch64-2022.04.04-0. I'm using Bitvise SSH Client to connect to the terminal.

  


• when using ffmpeg encode to hevc , but got 'rawvideo' [closed]

  3 septembre 2023, par 112292454

  i tried use ffmpeg to convert some types video to h265 to save disk space
but for some video, successfully converted and the file size smaller, but cannot play。
the result video codec name is "rawvideo",not hevc.

  


  the ffporbe of raw video is

  then, i used ffmpeg simple
(I'm guessing that this problem is just a stupid mistake of newbie,maybe like not use avi ? And the raw video is nsfw, maybe not suitable for release, XD--------but if really need it,can also supply)

  does i need any config to specify in ffmpeg commands to get the right codec ?
(btw, does this video bitrate is normally ?)
