Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

How can I output every other TS packet (of an MPEG Transport Stream file), into one output file, using FFMPEG ?
9 août 2022, par mustardCutterI want to copy every other MPEG transport stream packet (PID# 00000000 [I'm guessing this is the first #], 00000002, 00000004...), from one MPEG transport stream file, into one output file, and the other ones (PID# 00000001, 00000003, 00000005...) into another output file. The output files don't have to be MPEG transport stream files ; they could be PCM, etc. Each packet could perhaps be referenced by stream id (PID #) or by Bytes, as each one is 188 Bytes, except perhaps the last packet.


I'd prefer to not use HLS or sequence muxer or concat if they require that I separate all the TS packets from one TS file into a folder first (as that would make many thousands of them), and I'd rather not deal with log or text or playlist files if I don't have to do so. I can't rename the PIDs, as their naming should remain what it is for a later step. I can't glob since it isn't an image file, though if I have to, perhaps I can read it in as if it's an image file sequence and glob so as to group the odd PID #s as an 'odds' input and glob to group the even PID #s as an 'evens' input. I don't think I can use '%08d' on the input as a stream id, because what I'm doing to each packet differs from what I'm doing with the previous packet, as to its destination output file. Perhaps there is some solution using some loop, complex function, counter, or perhaps preferably some 'if' statement, though I'd like it to be done in FFMPEG rather than by the OS using some terminal trickery. I don't know if you can use '|' (backslash pipe) to pipe within FFMPEG (or to execute multiple FFMPEG commands sequentially) independent of the OS/terminal trickery ; (I'm guessing '&&' doesn't work within FFMPEG commands independent of the OS/terminal).


In case it is helpful to know, the TS file is created from an MP4, so perhaps there is some way to transmux so that the packets are getting created in the end sequence needed and then renamed to what they would be if I had just transmuxed from MP4 to TS (though technically I'm transcoding audio [1 or 2 channels] from AAC to AC3 in the transmux step, but the video is h.264 and just copied into the TS file).

How to convert messed-up .vtt sub file from youtube-dl —write-auto-sub download ?
27 septembre 2023, par perry_the_pythonMy goal is to download a YouTube video with auto-generated subtitles in a separate file like
.vtt,.srt, etc.

I am currently trying to achieve this with
youtube-dlbut I am open to other solutions if needed.

When I run the following command, it downloads the video as
.mp4(which is fine) and a separate.vttfile, but the.vttseems to be messed-up somehow and displays all the text for the whole clip at once instead of the specified times.

Command I am running :


youtube-dl --write-auto-sub https://www.youtube.com/watch?v=Roc89oOZOF4&list=PLJBo3iyb1U0eNNN4Dij3N-d0rCJpMyAKQ&index=45


Downloads this .vtt :

I have read that this may be done on purpose by YouTube.


Even if this is true, is there any way to convert this
.vttto a usable format or simply download correctly-formatted auto-generated subtitles from YouTube ?

Python, FFMPEG, cmd-line preferred, but anything is helpful !


Thanks ! Any and all assistance is greatly appreciated !

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 :
