• FFMPEG, faulty input with only a few keyframes ?

  9 août 2020, par browncatmegazord

  I have this video I can watch on MPC-HC alright, but I've been trying to re-encode it with FFMPEG to no avail.

  


  The video unerringly stops 5 minutes into the clip and freezes. Checking the key frames it would seem like the last keyframe is indeed at around the 5 minute mark, even though the video is completely watchable for its entire duration of upwards an hour. I've been looking into finding a way to repopulate the index of keyframes or something, but the answer eludes me.

  


  Both Handbrake and Premiere Pro fails to handle this video properly as well. Premiere Pro just imports it as though it's 5 minutes long, and Handbrake freezes when the encoding reaches the 5 minute mark.

  


  Even doing a -c copy would give me an output that terminates at the 5 minute mark.

  


  What can I do to fix this ?

  


  Edit : Added log as requested.

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


  



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

  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.

• 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"))
