Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -
HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.

Cryptic `ffmpeg` + Python error : `Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_crop_1`
5 août 2022, par mattze_frischI want to use
ffmpegwith Python in a Jupyter notebook to create a video from 2000 PNG image files generated bymatplotlib. I'm on a Windows 7 machine.

The frames are very narrow and high, so I'd like to cut them vertically into seven equal-sized "tiles" using
cropand stacked those "tiles" horizontally usinghstack, but I'm getting only getting cryptic error messages :

Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_crop_1


What is the problem here ? Also, how does one interpret this cryptic error message at the end of the log output :


Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_crop_1

E.g. what is
input pad 0, why is itunlabeled, and why can't it find a matching stream ?

(PS. : Yes, I do have a habit of excessively documenting my code. ^^)

Dash output with ffmpeg not producing durations specified with -seg_duration
30 juillet 2022, par CodieThere is a .mp4 file of 35 MB and 51 seconds. I have to create 51 chunks, each corresponding to 1 second with a size of less than 1MB (the total size should be almost the same as the original file). Please note that I have to implement lossless converting.


I've tried many times, but it just produces about 10 files above 10 MB.

That I Downloaded With This Python Program (m3u8 File Does Not Work !) :


import requests
import shutil
import os
import subprocess


def strip_end(text, suffix):
 if not text.endswith(suffix):
 return text
 return text[:len(text)-len(suffix)]


def download_file(url):
 cwd = os.getcwd()
 command = f"wget -O {cwd}/ts_files/{url.split('/')[-1]} {url}"
 subprocess.call(command, shell=True)


base_url = "https://stream.example.com/video/2021/example/720p_{}.ts"

if not os.path.exists('ts_files'):
 print('ts_file folder is not found, creating the folder.')
 os.makedirs('ts_files')

i = 1
while True:
 if len(str(i)) == 1:
 num = f"00{i}"
 elif len(str(i)) == 2:
 num = f"0{i}"
 else:
 num = str(i)
 url = base_url.replace("{}", num)
 r = requests.get(url, stream=True)
 print(f'downloading {i}')
 if r.status_code != 404:
 download_file(url) # comment out this line to download ts files.
 else:
 print("404")
 break
 i = i+1

cwd = os.getcwd() # Get the current working directory (cwd)
TS_DIR = 'ts_files'
with open('merged.ts', 'wb') as merged:
 for ts_file in os.listdir(f'{cwd}/{TS_DIR}'):
 with open(f'{cwd}/{TS_DIR}/{ts_file}', 'rb') as mergefile:
 shutil.copyfileobj(mergefile, merged)



My Problem Is When I Want To Convert All This Files To One .ts File And Then An MP4 File With ffmpeg, I Get An Error :

Are They Encrypted Or Something ?
I'm Trying To Do This Works With Debian 11.3.0-4, Python 3.10.5


Edit : Thanks Johnny, I Saw This Post : How to concatenate two MP4 files using FFmpeg ?
I Tried But I Get An Error Again !
