change audio part from mkv video file to flac audio file without losing quality [closed]
29 août 2023, par Jimmy wuhow could I write a Linux command to manipulate ffmpeg to change audio part from mkv video file to flac audio file without losing quality ?


I use following command and I found that the size of audio file is almost the same as video file.


ffmpeg -i "2023-08-28 15-32-02.mkv" -ss 0:0:0 -to 1:9:2

8 -vn -c:a flac 2023_08_28_CPU_DV_1.flac



what command should I use ?


I want to change "only audio part" from mkv video file to flac audio file without losing quality,


then the size of file would not be that big

Cutting and rejoining videos causes audio de-synchronization using ffmpeg [closed]
10 décembre 2023, par DonotaloThis is the original post. I'm not getting any answer there so I thought may be the programming community knows the answer.


Main Post


I'm trying to cut a video into pieces and rejoin them using
ffmpeg
on Windows 11 x64. Here's the details offfmpeg

I've a video file in MKV format. I've cut it into 3 pieces using the following command :


ffmpeg.exe -ss 0:0:0 -i input.mkv -t 0:54:15 -c:v hevc_amf -b:v 3M -c:s mov_text seg-01.mp4
ffmpeg.exe -ss 0:54:29 -i input.mkv -t 0:35:35 -c:v hevc_amf -b:v 3M -c:s mov_text seg-02.mp4
ffmpeg.exe -ss 1:30:12 -i input.mkv -t 0:4:10 -c:v hevc_amf -b:v 3M -c:s mov_text seg-03.mp4



The audio is copied in all 3 pieces like original. Now I'm joining them using the following command :


ffmpeg.exe -y -f concat -safe 0 -i .\join.txt -c:v hevc_amf -c:a copy -c:s copy -fflags +genpts out.mp4



where,
join.txt
is :

file seg-01.mp4
file seg-02.mp4
file seg-03.mp4



ffmpeg
throws the following warning :

[mp4 @ 000002a5cf9cc040] Non-monotonic DTS in output stream 0:1; previous: 156240896, current: 156240084; changing to 156240897.
This may result in incorrect timestamps in the output file.

This may result in incorrect timestamps in the output file.



I've observed that audio is de-synchronized after the places where I cut.


How to keep audio, video and subtitle synchronized after cutting and rejoining the video using
ffmpeg
?

Cannot seem to work with mp3 files in pydub
14 janvier 2023, par NegativePotatoI have been trying to open mp3 files on pydub, I have ffmpeg in path and whatnot, but I get errors whenever I attempt to use pydub with mp3 files. Wav files work fine of course.
This is my code for testing purposes (copied directly from online) :


from os import path
from pydub import AudioSegment

# files 
src = "Meet.mp3"
dst = "test.wav"

# convert wav to mp3 
sound = AudioSegment.from_mp3(src)
sound.export(dst, format="wav")



And this is my output for that code :


C:\Users\aiden\OneDrive\Desktop\VietnameseAudioConnector>py test.py
Traceback (most recent call last):
 File "C:\Users\aiden\OneDrive\Desktop\VietnameseAudioConnector\test.py", line 9, in <module>

Sorry if this ends up being obvious, I am new to using python. Thank you for the help !
