Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

Overlaying video with text - ffmpeg speed
12 février 2017, par SebadcI’m developing an app that has a functionality similar to Snapchat’s, in which you can add text to an existing video and save it on your phone.
I got this to work using ffmpeg’s "-drawtext" filter. The problem is that I’m getting a noticable delay (20 seconds or so) when adding text to videos, even though they are not too big (around 10 seconds length).
Can anyone point me in the right direction on how to reduce this delay ? Taking Snapchat as reference, they overlay high quality videos with text with little to no delay.
I’ve read about extracting the video’s frames and overlaying them manually, but shouldn’t that take longer ?
Thank you for your help.

FFmpeg to trim, pause and speed up
4 septembre 2020, par João AbrantesI have a single video and I want to transform it in the following way :


From the beginning of the video until the
end_of_part_1
I want the video to be at 1x speed.
Then I want the frame of the video atend_of_part_1
to be rendered for one second (with silent audio).
From the next frame to theend_of_part_2
I want the video to be played at 2x speed.
From the frame afterend_of_part_2
to the end I want the video to be played at 1x.

What is the best way to achieve this with
FFmpeg
?
