• trying to play audio from youtube with ffmpeg on discord.py rewrite

  13 septembre 2021, par Bobby Cook

  im trying to use a discord bot that plays music, but im getting errors when i run this code and python crashes, and i cant quite figure out whats wrong, except for that its around the @client.command(pass_context=True) async def play(self, ctx, *, url): print(url) server = ctx.message.guild voice_channel = server.voice_client
block. the i apologize for wasting all your time, im really bad at this, and i didnt even write most of this.

• Can't play MP4 after download

  14 août 2018, par joe

  I am using a downloader program in Firefox to download videos playing in Firefox. Most of the time final MP4 is playable. But sometimes I get MP4 file that looks good(shows file size) but shows no length of video in file explorer.

  I get this error log.

  Could not get information from media 'ESPN 2 (HD) Live Stream Channel' from file 'C:\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4'. The file might be corrupted.

  [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000024c3900] moov atom not found

  C :\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4 : Invalid data found when processing input

  It looks like moov atom is missing thus can’t aggregate PART file into final playable MP4.

  I understand that during download, PART file is created. Then later PART is aggregated into final MP4.

  So question is how can I make this MP4 to play ?
  or is it impossible to play cus moov atom was not properly downloaded ?

  Any thoughts ?
  Thanks

• How to downscale video using subprocess and then piping the data over to stdout and play using ffplay and save it as well

  2 avril 2021, par ZeroDay Fracture

  I am trying to use ffmpeg to downscale a video and pipe the stdout data to ffplay to play the new downsized video by piping it to ffplay on aws lambda.

  


  This is the command I have so far, but for some reason adding a scale option is not working.

  


  I am trying to run this command locally before I deploy it on python with subprocess command. I need the raw video to be able to save into database for streaming the data in realtime.

  


  %ffmpeg -i sample.mp4  -vf scale=240:-2 -f  mpegts -c:v copy -af aresample=async=1:first_pts=0 - | ffplay -

  


  adding the scale optioin for some reason is saving the video as the name scale=240 :-2 which does not make sense.
