  • Capture cctv camera with iphone application using IP

    22 septembre 2021, par Bittu

    I want to develop a cctv camera app and I don't know what steps I need to take.
i have the data below for connecting cctv camera :

    



      

    • Ip address

      • 


    • port ID

      • 


    • user name

      • 


    • password

      • 


    



    i checked live555 and RTMPStreamPublisher demo from here, but i don't know where I should start. i also read that i should use the ffmpeg framework.

    



    What I want is an app similar to kView on itunes. This app is able to stream a cctv camera feed with the above configuration detials

    



    Does anyone know what direction I need to go in ? Is there a demo or open-source app that accomplishes this ?

    


  • Cannot play DAV to MP4 converted H.265 video file with hvc1 tag in iPhone

    21 août 2023, par Venkata Subbarao

    I have converted H.265 video file in dav format from Dahua camera using following commands. Both of the generated mp4 video files are NOT playable in iPhone default player. However, the generated video files are playable in VLC player.

    


    ffmpeg -y -i hevc.dav -c:v copy -tag:v hvc1 hevc.mp4
ffmpeg -y -i hevc.dav -tag:v hvc1 -c:v copy -f mp4 -movflags frag_keyframe+empty_moov hevc.mp4


    


    Generated video file plays only if I re-encode the video using following command.

    


    ffmpeg -y -i hevc.dav -c:v libx265 -tag:v hvc1 hevc.mp4


    


    Re-encoding is time consuming. So, please let me know, if I am missing any flags in the above commands.

    


  • HLS Content Throwing 403 Errors on iPhone Indeterminately [closed]

    10 août 2023, par Shishir Jakati

    I am facing an issue with video content that I have converted to HLS playlist content (using ffmpeg) added to an S3 bucket that is shared through a Cloudfront Distribution. My scenario is the following :

    


    I have a bucket called bucket-a, with a "folder" video-1 which contains the following files :

    


      

    • output.m3u8

      • 


    • output0.ts

      • 


    • ...

      • 


    • output15.ts

      • 


    • audio/

        

      • audio.aac

        • 


      


      • 


    • image.jpg

      • 


    


    All items in bucket-a are blocked from public access through S3. Content is only vended through a Cloudfront distribution which has origin bucket-a. I am able to access https://<distro>.cloudfront.net/path/output.m3u8</distro> on a desktop browser without fail, and no errors thrown. But the file output.m3u8 and all .ts files are not available on iPhone mobile browsers. The part that is peculiar is that this is not true for all playlist content in bucket-a. For example, I have a "folder" video-2 within bucket-a that has the same file structure as video-1 that is completely accessible through all mobile browsers.

    &#xA;

    Here is an example master playlist error : https://dbs3s11vyxuw0.cloudfront.net/bottle-promo/script_four/output.m3u8

    &#xA;

    Even more head-scratching is that I am able to access all the playlists that are within this playlist.

    &#xA;

    What I've tried :

    &#xA;

      &#xA;
    • Initially, I believed the issue to be due to the way the video was transcoding so I standardized the video transcoding.

      • &#xA;

    • Then I believed the issue to be due to CloudFront permissions, though those seem to be fine.

      • &#xA;

    • I've validated my stream here : https://ott.dolby.com/OnDelKits_dev/StreamValidator/Start_Here.html

      • &#xA;

    &#xA;

    Not sure which way to turn.
