• ffmpeg with Quick Sync Video (qsv) gets stuck

  28 avril 2023, par Juliano B. Nequirito

  I've compiled ffmpeg in an Arch Linux distribution with support to Intel Quick Sync Video. But ffmpeg gets stuck when I try to run it :

  


  $ ffmpeg -debug -hwaccel qsv -qsv_device /dev/dri/renderD128 -c:v h264_qsv -i test_video.mp4 -c:v hevc_qsv output.mp4

  CPU starts being used intensively and then nothing happens.
Does anybody have any clue on it ?

  


  I have an Intel i7-8550U (8th gen Kaby Lake) processor with 4 cores (8 threads).

  


  I have also used these options to ffmpeg, getting the same results :

  


  ffmpeg -loglevel debug -init_hw_device qsv=hw -filter_hw_device hw -hwaccel qsv -hwaccel_output_format qsv -i test_video.mp4 -vf 'format=qsv,hwupload=extra_hw_frames=64' -c:v hevc_qsv -f mp4 output.mp4


  


  With VAAPI, transcoding runs flowlessly :

  


  ffmpeg -init_hw_device vaapi=intel:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device intel -filter_hw_device intel -i test_video.mp4 -c:v hevc_vaapi -f mp4 output.mp4


  


• Why is the ffmpeg process in discordpy terminating without playing anything ?

  18 janvier 2024, par Bummbumm6

  I'm making a discord bot for playing music (ik very unoriginal) and everytime I try to play music, it gives this error :

  


  2023-02-18 12:31:54 INFO     discord.player ffmpeg process 4024 has not terminated. Waiting to terminate...
2023-02-18 12:31:54 INFO     discord.player ffmpeg process 4024 should have terminated with a return code of -9.


  


  It is in the voice chat and didn't play anything. Here's my code if you need it :

  


  print("defining functions")
import discord, pytube, os, threading
from moviepy import editor
from discord.ext.commands import Bot
intents=discord.Intents.default()
intents.message_content = True
intents.voice_states = True
bot = Bot("b!",intents=intents)
check = False
token = "redacted"
@bot.command()
async def play(ctx, arg):
            await ctx.send("Downloading...")
            try:
                yt = pytube.YouTube(arg)
                print("STREAM: "+str(yt.streams.filter(only_audio=True,mime_type="audio/webm",type="audio",abr="160kbps")))
                def download(yt):
                    print("DOWNLOADING STREAM TO AUDIO.WEBM")
                    yt.streams.filter(only_audio=True,mime_type="audio/webm",type="audio",abr="160kbps").order_by("abr").first().download(filename="audio.webm")
                    print("EXPORTING TO MP3")
                    editor.AudioFileClip("audio.webm").write_audiofile("audio.webm"[:-5] + ".mp3")
                    os.remove("audio.webm")
                    print("DONE")
                thread = threading.Thread(target=download, args=(yt,))
                thread.start()
                thread.join()
                try:
                  channel = ctx.author.voice.channel
                  try:
                    vc = await channel.connect()
                  except Exception:
                    ctx.send("already in vc, one sec")
                except Exception:
                    pass
                vc.play(discord.FFmpegPCMAudio(source="audio.mp3", executable="./ffmpeg"))
            except Exception:
              pass
bot.run(token)



  


  It worked on my computer in VS Code, but I wanted to test it on Replit and only there I got the error. I tried :

  


  

  1. Reinstalling discord, pynacl, even pytube and moviepy.

  


  2. Using a local copy of ffmpeg on replit, see line 36.

  


  3. Adding the intents that were described in a different thread.

  


  


  One thing that always happens is the exit code being -9 but the process number changing (ofc). I saw a GitHub Issue about this too which is not showing a fix so how do I fix that ?

  


• ffmpeg conversion failed error while splitting a 1.57GB .tif file

  12 janvier 2023, par Minai

  I am running ffmpeg to split a large .tif image of dimensions 25966 * 64114 into grids 0f 256 * 256 pixels but am getting an error.

  


  I ran the ffmpeg command on an 1883 * 1361 pixel .jpg image named coral2

  


  Here is the image

  


  Using the following command :

  


  ffmpeg -i coral2.jpg -qscale:v 1 -vf "crop=256:256:0:256" coral2-0-256.jpg

  


  Here is the crop

  


  When I run the same command on a 1.57GB .tif image :

  


  image.tif -qscale:v 1 -vf "crop=256:256:0:256" image%01d.tif

  


  I get the following error :

  


  


  


  C :\Users\gwmin\Downloads\coral\southbayapal>ffmpeg -i image.tif -qscale:v 1 -vf "crop=256:256:0:256" image%01d.tif
