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 (...) -

Best language to use for AWS Beanstalk worker, for Watermarking videos
16 juin 2017, par RAJ CHOURASIAI have a requirement such that, for each customer, the video content I have has to be separately watermarked and kept in the cloud. Also, this whole process is to be automated.
The way I have figured the architecture is that :
- I would use AWS SQS queue, to update for which Customers, which set of videos have to be watermarked
- AWS Beanstalk worker would read the queue, pick up the videos from a S3 location, watermark the required videos and save back in a separate S3 location
Total size of all the videos can be upto 15GB, which takes more than 24hrs to watermark, using "ffmpeg", so I will also require
- Ability to parallel process, use multiple CPU cores if available
- Ability to auto scale, when required
In order to achieve this, what would be the best Language to use, to write the AWS Beanstalk worker logic ?

FFMPEG delay mutliple overlay videos (with different delays)
28 avril 2019, par Bamba675I’m trying to overlay a video (for example a report) with different other videos or images, like hints to the facebook page or a hint to the website. These other videos or images are smaller than the original and sometimes transparent (rgba).
I already tried to overlay multiple videos, which works pretty well :
ffmpeg -i 30fps_fhd.mp4 -i sample.mp4 -i timer.webm -i logo.jpg -filter_complex "overlay = x=100:y=1000, overlay = x=30:y=66:eof_action=pass, overlay = x=0:y=0" -acodec copy -t 70 out.mp4
But now, I want to start some videos or images not at the beginning of the video, instead after a period of time.
I found flags like ’itsoffset’ or ’setpts’, but I dont know how to apply them on this ’multiple video / image overlay command’.LG Bamba

Cutting multiple videos with x amount of time from the end (ffmpeg ?)
25 octobre 2020, par Jack FitzpatrickI have no history with ffmpeg, but I am assuming this would be the right tool for the job. I am trying to cut a folder of videos with different lengths. I want to cut them all to be 12 seconds from the end. That is : on a 30 second video I would be left with 00:18 - 00:30. 00:00-00:17 would be deleted.


I am on mac OS Mojave. It seems that ffmpeg is the right tool for the job to batch edit these videos. Can someone walk me through this ? I have some basic understanding but will need the code/script explained so that I can apply it to my own use. Thank you very much.
