subprocess.CalledProcessError command returned non zero exit status 1 even though the command works in the CMD
11 janvier 2024, par Lucas Soreauin Python, I want the duration of a video file without the FFmpeg Python library. This is the problematic line :


output = subprocess.check_output(['ffprobe', '-i', path, '-show_entries', 'format=duration', '-v', 'quiet'], universal_newlines=True)


And it gives this error :


subprocess.CalledProcessError: Command '['ffprobe', '-i', '"C:\\FFmpeg\\Encodes\\Forza Horizon 5\\FH5 AV1.mp4"', '-show_entries', 'format=duration', '-v', 'quiet']' returned non-zero exit status 1.


But the most important, and what I don't understand, is that, in the CMD, when I input
ffprobe -i "C:\FFmpeg\Encodes\Forza Horizon 5\FH5 AV1.mp4" -show_entries format=duration -v quiet, I'm getting :

[FORMAT]
duration=101.480000
[/FORMAT]


In the Python file, the [FORMAT] tags will be removed so that I only have the duration, so there is no error. What's wrong with it ?


By the way,
raise RuntimeError("command '{}' return with error (code {}): {}".format(e.cmd, e.returncode, e.output))doesn't return anything

I've tried removing unncessary things such as
universal_newlines=True, and tried to search for it online, but what I found online doesn't include the fact that when I run it in the CMD, it works

How to generate HLS stream multiple qualities (Representations) while capturing webcam
27 janvier 2023, par LUKA TADIĆI want to generate multiple qualities (Representations) for HLS stream while capturing from webcam. I am using ffmpeg_streaming python package. I can generate one quality (Representation) at a time, but when i try to generate more than one, I get this error :

This is the code :


import ffmpeg_streaming
from ffmpeg_streaming import Formats,Bitrate, Representation, Size 

video = ffmpeg_streaming.input('Fantech Luminous C30', capture = True)

_360p = Representation(Size(640, 360), Bitrate(276 * 1024, 128 * 1024))
_480p = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
_720p = Representation(Size(1280, 720), Bitrate(2048 * 1024, 320 * 1024))

hls = video.hls(Formats.h264(),hls_list_size=10, hls_time=5)
hls.flags('delete_segments')
hls.representations(_360p, _480p, _720p)
hls.output('C:\\Users\\ltadic\\Desktop\\camera_stream\\hls1.m3u8')


I was expecting to get _360p, _480p and _720p qualities, but my program crashes. If I try same thing for DASH stream, I generate these qualities without any problem.

Flash / FFMPEG / Linux Video Broadcasting [closed]
4 avril 2013, par Grant AdkinsI'm looking for a way to have a "virtual" online tv network.. kinda like shoutcast radio with auto dj where I can set the programing lineup or just randomize from files on the server and maybe the possibility of having live streams as well.. all to be streaming 24/7 on a website hopefully with a flash or dependable player..
I've kinda looked into nullsoft video
but does anyone else know a solution that might help ?
