  • Raspberry Pi cannot connect to IP camera, while Windows PC can ?

    28 novembre 2020, par gf000

    I have an IP camera (Provision ISR, DI-320IPS-VF, 2MP IR Vari-Focal Dome IP Camera). When I connect it to my router (it is a 10 or 12 years old TP-LINK TL-WR1043ND), it will immediately show up in "IP Manager" (this is a program by the manufacturer) on my Windows PC. If I double click on the camera's row, Internet Explorer opens up, and everything is working fine. On the same Windows PC, if I open VLC Media Player, and paste this URL : rtsp ://username:password@localipaddress:554/profile1
It works fine.

    


    I have also a "Raspberry Pi 4 model B 4 GB RAM", which is connected to the same router. If I open VLC Media Player, and I paste the same URL, it doesn't work. I also created an ffmpeg one-liner, which would take a photo, but that is also not working.

    


    My final goal would be to be able to take photos with that ffmpeg one-liner, on the Raspberry Pi.

    


    Maybe the Raspberry Pi is not powerful enough to handle the stream ? Or, could it be the problem that the IP-camera is sending H-264 / H-265 video stream, and the Raspberry Pi cannot handle it ?

    


    Thank you for your help. Any idea could help me.

    


  • Fast Video Streaming and Upload Android

    6 avril 2016, par vminind

    Fast Streaming & Uploading Videos On Mobile Apps with AWS S3

    Im developing a app witch has Android, iOS Clients were users can upload videos and photos and view as news feed. I store my video file on Amazone s3. Video length is limited to 30sec.

    When user is uploading 30 sec video from their gallery there are some high quality videos witch is even exceed 100MB so those video files take ages to upload. So i tried to convert them before upload using ffmpeg-android library but it also take almost same amount of time to convert the file so it seems this solution also point less. (convert in the scene reducing the video resolution and frame rate)

    Im using ExoPlayer to play videos

    Note : Videos uploading from iOS are not that huge files.

    I want videos to upload fast and stream fast. Its big help if anyone can share their thoughts on this.
