python suggests ffmpeg installation when it is installed
17 janvier 2021, par FNTEI have a problem related to the bar_chart_race python package. I have installed ffmpeg but when I execute my code, I get :


You do not have ffmpeg installed on your machine. 
Download from here: https://www.ffmpeg.org/download.html.



I know that I have used this package before and it was all good. I have installed ffmpeg version :


ffmpeg -version
ffmpeg version 4.2.3 Copyright (c) 2000-2020 the FFmpeg developers
built with gcc 9.3.1 (GCC) 20200523



Do you know what I can do ? I have bin folder in path.

How do I change audio language using ffmpeg in video files contaning two or more audio tracks
19 mai 2020, par warezsoftwarezI am transcoding video files, that contain 2 audio tracks - Polish and English. Unfortunately my transcoder messes somehow with metadata, and at the output, when I'm checking video file using MediaInfo, i see that both audio tracks are described as English. I'd like to change description of 1st audio track to Polish, so accordingly to ffmpeg documentation :



To set the language of the first audio stream:
ffmpeg -i INPUT -metadata:s:a:0 language=eng OUTPUT




Unfortunately, running command :



ffmpeg -i INPUTPATH -metadata:s:a:0 language=pol OUTPUTPATH




to overwrite input file resulted in saving file thats size is 63KB but it is described as Polish audio (no second audio track - English somehow was deleted)



When I used this command, to save output file as another file, to avoid overwriting if something misses (which is current situation), but using parameter
-metadata:s:a:4
because I thought that maybe I'm reading metadata from ffmpeg incorrectly, it resulted in saving output file as 800Mb with only English (no Polish track).


I don't know what should I change in this command to run as I want it to - just changing metadata of first audio track language to Polish.



Here is full ffmpeg output :



C:\Users\user>ffmpeg -i F:\Path\33244813_6000_1_trailer.mp4 -metadata:s:a:4 language=pol F:\Path\testtest.mp4

FFmpeg return 'invalid argument' only for some runs, even tought is the same code
20 septembre 2021, par Gustavo MarinhoI have a code in python where i need to use FFmpeg to merge a audio and a video downloaded using pytube together :


for video in p.videos:
 video.streams.filter(file_extension='mp4',resolution='480p')[0].download(parent_dir+'/mp4/processing/video')
 print(video.streams.filter(only_audio=True)[1].download(parent_dir+'/mp4/processing/audio'))

 subprocess.run([

 r'c:\FFmpeg\bin\ffmpeg', '-i',
 os.path.join(parent_dir+'/mp4/processing/video',video.streams.filter(file_extension='mp4',resolution='480p')[0].default_filename)
 ,'-i',
 os.path.join(parent_dir+'/mp4/processing/audio',video.streams.filter(only_audio=True)[1].default_filename),
 '-c:v','copy','-c:a','copy',
 os.path.join(parent_dir+'/mp4',video.streams.filter(file_extension='mp4',resolution='480p')[0].title+'.mp4')

 ])



I tought the code was working perfectly, but in some cases, the FFmpeg returns "invalid argument", like this example :

For some reason, the FFmpeg say that my output name is invalid, but i don't understand why, given that i ran the code multiple times before and it worked perfectly


Thanks in advance, sorry for my bad english :3
