Error while concatenating audio files with ffmpeg
17 janvier 2023, par RubWhile concatenating audio files with


ffmpeg -safe 0 -f concat

PyDub : ffmpeg header missing
7 février 2024, par Ray SiplaoI made a simple Python program that add short pauses at the start of mp3 files


import os

from pydub import AudioSegment

AUDIO_DIR = 'C:\\Users\\Ray\\Downloads\\sentence-audio'
OUT_DIR = 'C:\\Users\\Ray\\Downloads\\out-audio'

pause = AudioSegment.silent(duration=400)

for fname in os.listdir(AUDIO_DIR):
 print(f'Processing {fname}')
 newf = os.path.join(OUT_DIR, os.path.basename(fname))
 if os.path.isfile(newf):
 print(f'{fname} exists')
 continue
 audio = AudioSegment.from_mp3(os.path.join(AUDIO_DIR, fname))
 new = pause + audio
 new.export(newf, format='mp3')

While running this program, I received the below error message for a particular mp3 file

I thought at first that the mp3 file is corrupt, thus it is unplayable. But, when I played the file in a media player, it was fine.


I don't know how to resolve this issue. Is there any workarounds ?

How do I install ffmpeg on one EC2 Amazon Linux instance that can stream a mp4 ? [closed]
12 septembre 2020, par starpebbleGood day. How can I install ffmpeg on an EC2 amazon linux machine that can stream a mp4 ?


The goal : an ffmpeg install on EC2 Amazon Linux that can stream one mp4 to one rtmps endpoint. Then, create an integration test suite with it.


Is it just me or is ffmpeg a little crippled on EC2 Amazon Linux ?


Example :


ffmpeg -re -i input.mp4 -c:v libx264 -b:v 6000K -maxrate 6000K -pix_fmt yuv420p -s 1920x1080 -profile:v main -preset veryfast -g 120 -x264opts "nal-hrd=cbr:no-scenecut” -acodec aac -ab 160k -ar 44100 -f flv rtmps:///app/



Linux OS :


Linux version 4.14.193-113.317.amzn1.x86_64 (mockbuild@koji-pdx-corp-builder-60005) (gcc version 7.2.1 20170915 (Red Hat 7.2.1-2) (GCC)) #1 SMP Thu Sep 3 19:08:08 UTC 2020



The stackoverflow answer to similar questions fail to install a ffmpeg that can stream.


An installation script such as Install FFMPEG Library on EC2 Server fail this year.


The static downloads referenced on John Van Sickle-FFmpeg Static Builds fail to stream to IVS. I tried the i686 release, my first guess for an x86_64 instance.


The git source tree compiled binary fails to stream. Example : The tip of the tree isn't what I expected because the binary fails to recognize switches like
-preset
.

I'd love to be able to explain streaming to anyone. Thanks.
