Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

FileNotFoundError : [WinError 2] The system cannot find the file specified (using ffmpeg.probe())
28 octobre 2022, par Hjalti Geir ÁgústssonI'm trying to access metadata for a video using ffmpeg.probe() and it gives this error message. There is very little info on probe online.


import os
import ffmpeg


os.chdir('E:/F/Salvaged goods/Videos/Miro/Kvikmyndir/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO')

pprint(ffmpeg.probe(filename='Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO.mkv', cmd='ffprobe'))




I have also tried this, and got the same error message :


pprint(ffmpeg.probe(filename='E:/F/Salvaged goods/Videos/Miro/Kvikmyndir/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO.mkv', cmd='ffprobe'))



Here is the Traceback :

I use ffmpeg to encode and create MPEG file from a source MP4 file. In Mac the encoding is good but in windows it creates random green pixels [closed]
24 mai 2024, par Amudhan RI use ffmpeg 3.4.2 version to encode and create an MPEG-TS file using H.264 encoding. In both Windows and Mac the ffmpeg creates the video without any error. But the resultant video from windows having a green pixels on certain frames. No idea why this is happening.


Below is the encoding command :


ffmpeg -i VIDEO_SOURCE.mp4 -vf scale=720:480 -c:v libx264 -b:v 2M -minrate 2M -maxrate 2M -bufsize 2M -level:v 40 -profile:v main -bf:v 2 -r 30 -crf 22 -x264-params 'keyint=3:min-keyint=3:ref=2:8x8dct=0:weightp=1:subme=6:rc-lookahead=30' -c:a aac -b:a 130k -ar 48000 -f mpegts -filter_complex alimiter=level_in=1:level_out=1:limit=0.15:attack=7:release=100:level=0 VIDEO_ENCODED.mpeg


But the resultant video from windows having green pixels on certain frames. No idea why this is happening.
