• sudo checkinstall - installation failed

  18 décembre 2020, par Mathiem

  I'm trying to install ffmpeg on Raspbian by following these steps :

  



   cd ffmpeg
./configure --prefix=/usr
time make -j 8
cat RELEASE
sudo checkinstall


  



  but when I do the sudo checkinstall step, it gave me an error :

  



  pi@raspberrypi ~/ffmpeg $ sudo checkinstall -y

  Can anyone help me ? What can I do ? I'm not gonna lie, I'm a noob and I don't really know where to start, I tried 3-4 things but it didn't work.

  



  Thanks !

  


• ffmpeg failing when using discord.py

  I was making a bot with a rickrolling feature. It involves ffmpeg, but it always gives the following error :

  It keeps giving this error even when I switched to a different file, am I doing anything wrong ? I'm on Windows python 3.8.2, discord.py 1.6.0. Here is the code section :

  


  @bot.command(name="rickroll")
async def rick(ctx, channel: discord.VoiceChannel):
    connection = await channel.connect()
    connection.play(discord.FFmpegPCMAudio("rick.mp3", executable="ffmpeg.exe"))


  


• Removing both leading and trailing silence from m4a files using ffmpeg

  11 juin 2021, par Tejas Shah

  I have an audio file which has both leading and trailing silence and with the following specifics :

  



  Codec : MPEG AAC Audio (mp4a) Channels : Stereo Sample rate : 44100 Hz Bitrate : 253 kbps

  



  I want to remove the silences AND keep the quality intact.

  



  So far I've tried

  



  ffmpeg -i 1.m4a -af silenceremove=1:0.5:0:1:0.5:0 2.m4a 


  



  This is supposed to remove both the leading and trailing silences. 
But for some reason it doesn't remove the trailing silence. This seems to be a recurring problem. Found the following on another forum.

  



  http://ffmpeg-users.933282.n4.nabble.com/How-to-delete-digital-silence-tp4667256p4667356.html

  



  Also, ffmpeg reduces the bitrate to 128kbps. This I could fix by adding -ab 253k and making the command :

  



  ffmpeg -i 1.m4a -af silenceremove=1:0.5:0:1:0.5:0 -ab 253k 3.m4a 


  



  Now the problem is that the trailing silence isn't removed and when I want to process a batch of files I can't use the same bitrate (like 253kbps ) for every file. I'd like to know how VBR could be used for this case.

  



  I know I can use sox and use the silence and reverse features to trim the silences.

  



  http://digitalcardboard.com/blog/2009/08/25/the-sox-of-silence "Example 3 in this post"

  



  But sox has the following problems :

  



  

  1. It can't handle m4a files, I had to convert all files to mp3.

  


  2. When using the silence filter in sox it caps the bitrate at 128kbps.

     



     sox 1.mp3 2.mp3 silence 1 0.5 1% reverse silence 1 0.5 1% reverse
