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. -

ffmpeg - spark - azure databricks - error writing trailer of "filename.mp3" : Operation not supported
4 juillet 2021, par CRAFTY DBAI have been trying to figure out this tough problem.


I am trying to convert *.mp4 files to *.mp3 files.


I tried using MoviePy but I found out that is uses ffmpeg and was having the same issue.


I used these two articles to get the latest version of ffmpeg installed on the Azure Databricks Cluster during startup. I am using a single node cluster for this POC code.


Pyspark : Use ffmpeg on the driver and workers

https://ubuntuhandbook.org/index.php/2020/06/install-ffmpeg-4-3-via-ppa-ubuntu-18-04-16-04

The issue is that even the simplest command results in errors.


%%bash ffmpeg -i /dbfs/Craftydba/recording.mp4 /dbfs/Craftydba/recording.mp3


I even tried .wav as an output format and still the same issue.


I retested this command on a Data Science VM in Azure with Python and FFMPEG. It works fine on that OS/Build.


It has something to do with the version of the code on the spark cluster.


Any help is appreciated.


Sincerely


John Miner


PS : I am add a dump of the OS version as well as a ffmpeg error.

Convert RAW images to BMP format
3 juin 2021, par Tina JI received a
.raw
frame format (here is a sample) which contains the raw pixel values of a frame. And I've been told I can convert it to an image (.bmp or .png) usingFFMpeg
using following command. However, when trying, it doesn't work.

dd bs=16 dumpB4EncodeHLSAfterEncodeBuf1200IP_TS/dumpedYuv/image-1140.raw | ffmpeg -f rawvideo -video_size 2160 2160 -pixel_format nv12 -i - yuv.bmp



What is the problem ? Is there any ways to avoid use of
dd
and purely do it fromFFmpeg
?

Here is the error :
