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.

Webcam recording with FFmpeg through USB over UTP
13 septembre 2021, par z32a7ulI'm trying to record my webcam with FFmpeg.


I listed the devices with this line :


ffmpeg -list_devices true -f dshow -i dummy


And I test the settings with this one :


ffplay -loglevel verbose -f dshow -rtbufsize 100M -video_size 1280x720 -framerate 60 -video_device_number 0 -audio_device_number 0 -i video="C922 Pro Stream Webcam":audio="Microphone (C922 Pro Stream Web"


The first command outputs this :

However, if I use a USB cable extender (USB over UTP - This thing consist of two parts : the first one has a male, the second one a female USB A, and they are linked through RJ45 sockets and a Cat5e UTP cable), it does not work at all. The first command prints the same :

What can be the problem ? Is it the extender cable ? What are FFmpeg's requirement on USB cables (and extenders) ?
