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 (...) -

Requirement to trim video from front-end
30 octobre 2023, par user20663233I have a specific requirement to implement video uploading from the front-end Next Js framework to a third-party application. During this process, it is necessary to trim the first 20 seconds of the video, store the trimmed segment, and subsequently transmit it to the server. While initially considering the utilization of the FFmpeg library for video trimming, I've come to realize that I require server-side support, as hosting FFmpeg locally is not a feasible option. Therefore, I am exploring alternative solutions that would allow me to accomplish video uploads from the front-end while meeting these requirements.

Unsuccessful streaming webm video with ffserver - dimensions not set
5 juin 2015, par randomuser1I configured ffmpeg and ffserver. Now when I type :
ffmpeg -f dshow -list_devices true -i dummy
I get the list of video/audio devices :
[dshow @ 00000000045db680] DirectShow video devices (some may be both video and
audio devices)
[dshow @ 00000000045db680] "SF Camera"

ffmpeg -rtbufsize 1500M -f dshow -i video="SF Camera":audio="Microphone (Realtek High Definition Audio)" http://10.172.180.195:8090/feed1.ffm
but all I get is :

10.172.180.109 - - [GET] "/feed1.ffm HTTP/1.1" 200 79and that’s all, ffmpeg stops and returns to command line. Does anyone know what can be the problem here ?
Oh and one more thing that might be helpful - this is my ffserver.conf file :
