• How to encode an mp4 to the exact specs of another mp4 with FFMPEG

  15 décembre 2021, par BCooper

  I'm working on a batch file to concatenate 3 files together, as follows :

  


  1_Intro_Bumper.mp4,
2_Session.mp4,
3_Outro_Bumper.mp4


  


  I've run into problems with the session.mp4 having slightly different specs, causing the concat to have weird problems with speed/sync/etc, and found out that if I encode the Bumpers through Handbrake to the exact specs of the Session, then the concat works great.

  


  My question is : Can I bypass Handbrake here and include a line in my batch file to encode the Intro and Outro Bumpers to the exact specs of the Session ?

  


  Here's my current batch file :

  


  :: Create File List

for %%i in (*.mp4) do echo file '%%i'>> mylist.txt

:: Concatenate Files

ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4

:: Encode to x264

ffmpeg -i output.mp4 output_x264.mp4


  


  Thanks !

  


• http live streaming based on a m3u file

  23 mars 2018, par 3agelx45

  I have an account on a platform of streaming (legal !). This platform provide me with a m3u file, the content looks like follow :

  #EXTM3U
  
  #EXTINF:-1 tvg-id="" tvg-name="|| something ||" tvg-logo="" group-title="",|| CAT1 ||
  
  http://someurl.domain:1234/video1.ts
  
  #EXTINF:-1 tvg-id="" tvg-name="video2" tvg-logo="" group-title="CAT1 part 1",VIDEO1
  
  http://someurl.domain:1234/video2.ts
  
  #EXTINF:-1 tvg-id="" tvg-name="video2" tvg-logo="" group-title="CAT1 part 1",VIDEO2
  
  .
  
  .
  
  .
  
  etc

  This file works fine using vlc from home. but when I travel I use Hotels hotspots and some do block the connection to someurl.domain:1234.

  is it possible to stream the m3u file using a light http server (stream the file from server side and reroute result to http). The idea is run a small iptv server from home on my raspberry which will allow me to bypass the "censorship" faced with some hotspots.

  Thanks !

• Discord.py Musicbot Skip Command PermissionError

  28 mai 2021, par Ventior

  So as my first "major" project after starting to program, I've decided to make a Discord Bot. The problem here is my "skip" command. Somehow it works but I can't understand how.

  


  def play_next(ctx):
if len(songs_list) >= 2:
    print(songs_list,"before del")
    del songs_list[0]
    print(songs_list[0], "new song")

    
    try:
        if os.path.isfile("song.mp3"):
            os.remove("song.mp3")
    except PermissionError:
        print("permissionerror")
    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        ydl.download([songs_list[0]])
    for file in os.listdir("./"):
        if file.endswith(".mp3"):
            os.rename(file, "song.mp3")
    voice.play(discord.FFmpegPCMAudio("song.mp3"), after=lambda e: play_next(ctx))
    voice.isplaying()


  


  And the skip command :

  


  @client.command(pass_context=True)
async def skip(ctx):
voice.stop()
voice.skip()
try:
  os.remove("song.mp3")
except:
  pass
play_next(ctx)


  


  I know it isn't the best way of handling that, but I am just beginning to code and this is how I got it to work.
In the skip command, when I didn't use voice.skip() I would have gotten a PermissionError printed out in the console.

  


  With it included, I instead get the message "VoiceClient" object has no attribute "skip", but everything works in order so far. Can someone explain why ?
I mean if skip doesn't exist, then why does it work ? And how does it bypass the PermissionError ?
