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 (...) -

Why do I get "method DESCRIBE failed : 401 Unauthorized "
28 juillet 2021, par TheOliveTurtleLet me explain my problem, I am trying to access different channels in a DVR system.
I have successfully gotten access to a single camera (channel 1) by using opencv as such :


public_link = 'rtsp://test:test@192.168.1.48/cam/realmonitor'

cap = cv2.VideoCapture(public_link, cv2.CAP_FFMPEG)


The problem is I can't access the other channels with these parameters :


public_link = 'rtsp://test:test@192.168.1.48/cam/realmonitor?channel=3&subtype=0'

cap = cv2.VideoCapture(public_link, cv2.CAP_FFMPEG)


I've tried the following links :


- 

- rtsp ://test:test@192.168.1.48/cam/realmonitor ?channel=3&subtype=0
- rtsp ://test:test@192.168.1.48/cam/realmonitor ?channel=3&subtype=1
- rtsp ://192.168.1.48/cam/realmonitor ?channel=3&subtype=0&authbasic=dGVzdDp0ZXN0








I get this following error :




[rtsp @ 00000201ce582cc0] method DESCRIBE failed : 401 Unauthorized




I've noticed that even if I test with this URL (rtsp ://test:test@192.168.1.48/blablabla) it works just fine ! (ONLY Channel #1) but when I insert the symbol '=' into the URL string, I get the above error.


It's really frustrating, Any sort of help would be much appreciated.


PS : the user 'test' has admin privileges in the system.


I've tried to run the test with plain ffmpeg command like such :

ffmpeg -loglevel debug -i "rtsp://test:test@192.168.1.48/cam/monitor?channel=3&subtype=0" ./folder/output.m3u8

I get the following error :

Error : "No such option : -l" when running yt-dlp
12 juin 2022, par garsonI have adapted code from this Stack Overflow answer to try to download a video and use ffmpeg to alter it


yt-dlp "https://www.youtube.com/watch?v=PtkqwslbLY8" -o ffmpeg -i in.mp4 -vcodec libx264 -crf 23 -preset fast -profile:v baseline \
-level 3 -refs 6 -vf "scale=640:-1,pad=iw:480:0:(oh-ih)/2,format=yuv420p" \
-acodec copy output.mp4


However, when I run this I'm getting the error :


yt-dlp: error: no such option: -l


Any ideas of how to fix this ?
