Les statuts des instances de mutualisation
13 mars 2010, parPour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...) -
Encoding and processing into web-friendly formats

Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.

ffmpeg only processes first image
8 septembre 2020, par Michael PriceI have a directory of .png images (I had previously tried .jpg until I read somewhere ffmpeg prefers .png).


The images share a file numbering format cof000.png - cof358.png.


I want to convert those images into a moving picture format. MPG or MP4 will be fine.


The command I have tried is


ffmpeg.exe -framerate 25 -i cof%03d.png -r 6 output.mp4



I adapted the command from this post, here :


https://stackoverflow.com/questions/53778503/ffmpeg-video-slideshow-only-takes-first-image



Even after trying numerous different permutations of the command the final file only has the first image in it. I am using windows.


What ffmpeg command do I need to use on Windows to compile all 180 image files into a single moving image ?


Here is the output from using the command :

Concatenating on Windows throws "Invalid data found when processing input" while it works on Mac and Linux
15 février 2020, par miguelmorinI need to run a command with a nightly build of FFMPEG to report a bug on the
concat
protocol. I found it difficult to compile from source with libx264 support on Linux, and I want to spare my Mac computer, so I use the nightly build on Windows from Zeranoe.I call this command to concatenate the files :
ffmpeg -safe 0 concat -i files_to_combine -vcodec libx264 show.mp4
where
files_to_combine
is :file ./short_DSC_0013.MOV
file ./short_DSC_0014.MOV
file ./short_DSC_0015.MOV
file ./short_DSC_0016.MOV
file ./short_DSC_0017.MOV
file ./short_DSC_0018.MOV
file ./short_DSC_0019.MOVI call this command from the directory containing the video files and
files_to_combine
.On Windows with a nightly build, I get the error :
files_to_combine : Invalid data found when processing input
I changed
file ./DSC_0013.MOV
to these options, all with the same error :file 'short_DSC_0013.MOV'
file '.\short_DSC_0013.MOV'
file 'F:\short_DSC_0013.MOV'How can I debug this error, or what is the syntax for concatenating on Windows with a nightly build ?

I had mistyped the command. The right command has a

, which I found because the accepted answer was able to make the command work in a similar environment :ffmpeg -safe 0 -f concat -i files_to_combine -vcodec libx264 show.mp4

FFMPEG restream m3u8 to Youtube keeps returning "Failed to update header with correct duration & filesize" after 1st segment
12 septembre 2020, par user3263433I'm trying to retream a m3u8 live feed toYouTube but I keep running into errors.


When watching the feed in a webplayer it works fine.


The headers of the m3u8 file are as follow :


#EXTM3U
#EXT-X-VERSION:6
#EXT-X-TARGETDURATION:8
#EXT-X-MEDIA-SEQUENCE:127629
#EXT-X-DISCONTINUITY-SEQUENCE:0
#EXT-X-PROGRAM-DATE-TIME:2020-09-12T12:57:13.280Z



Here is the ffmpeg log :

It seems like it loads 1 .ts file fine but fails after that.


I'm currently using :


ffmpeg -re -i (urlToM3U8) -codec copy -f flv rtmp://a.rtmp.youtube.com/live2/(streamkey)
