1er avril 2021, par ashiyaa nunhuckI want to stream video from my drone real time to a WEBUI using ffmpeg. But i get the follwong errors.
The code works but i don't think ishould have gotten this error.
Can somebody help with this issue ? This is my drone commands along with the streaming video codes. I have only added the code to get data.
Below is the error :

Anomalie #4623 : Styles des fieldset dans l’espace privé
16 avril 2021, par nicod _Le principe est pas mal, mais je n’aime pas trop ces dégradés sur la fin des bordures, ça fait "pas net" et ça ne correspond à aucun autre élément d’UI.
Tu as essayé avec juste une bordure à gauche, mais très légère (en luminosité/opacité) et épaisse (0.33em) ?Pétouille : au niveau des marges, la légende d’un fieldset imbriqué devrait être plus proche de ses champs, que des champs du fieldset parent.
Et je trouve bizarre que l’input du fieldset imbriqué soit décalé lui aussi vers la droite, même si ça parait logique, c’est bizarre visuellement. -
