• Solution for VB6 to broadcast Webcam

  14 septembre 2018, par vantrung -cuncon

  Sorry, I know VB6 is decades ago, but I’m in a situation that I have to use VB6 to deliver live webcam stream beetween 2 PC in Server - Client Model program. Vb6-code holds the connection then I have no choice but to transfer all data via that connection.

  I’ve tried weeks for this, uncountable approaches but went to nowhere.
  My efforts focused on 3 major approaches :

  1/ Use ffmpeg to record live webcam as ".avi" file on hard disk, transfer parts of file to other end & play it. But I’ve stucked with a media-player that can play a "being written" avi file.

  Windows Media Player control told me "file already in use..." & VLC Plugin can’t even be added to VB6 (axvlc.dll).

  2/ Use ffmpeg to save live webcam as avi file, transfer each bit of that file to the other end, then in other end, extract 24 images / second from the avi to display continously in a picture box.
  This approach is ok except that my hard disk get fulled of images in a time of wink and my program get very slow before hanging.

  3/ Use ffmpeg to stream the live webcam to a rtp-port like this :

  ffmpeg -f dshow -i video="Lenovo EasyCamera" -vcodec mpeg2video -pix_fmt yuv422p -f rtp -an rtp://224.1.2.3:8191

  I’ve successfully watch the stream in VLC, but VLC(axvlc.dll) refused to be integrated into ancient VB6. And more important, I don’t know how to redirect/reroute the rtp stream to other PC with VB6.

  Any one please light me up ? (Any 3rd party component is welcomed)

• How to achieve real time video editing on Android ?

  3 octobre 2024, par Itamar

  I've been working recently on a video-editing-related project on Android, and am desperately looking for resources related to video editing on the platform.

  


  The only video-editing related "method" or information I could find was using the FFmpeg library, which is pretty rich in features and capabilities but works really slow, operations such as reversing a 10-second video can take as long as 30 seconds, which delivers a really poor user experience.

  


  That being said, it seems that there are tons of Android video-editing apps that are capable of doing everything FFmpeg can, only in almost immediate periods of time (apps such as InShot, PocketVideo or even the previous musical.ly TikTok).

  


  I've tried researching and searching for information on the topic in almost any reasonable place (Google, GitHub, YouTube, the Android developer center, and even on "support" pages of the above-mentioned apps) to no avail (no explanatory documents, no open source libraries, not even demo apps), if anyone could shed some light on the subject that would be much, much appreciated !

  


  Thanks.

  


• Rtsp streaming, no live

  14 août 2018, par Alejandro

  i follow this topic for streaming rtsp here
  now this is my conf in the server : ffmpeg -v info -i rtsp://XXXXX.ddns.net/onvif1 -c:v copy -c:a copy -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 /var/www/html/p433/assets/video/test.m3u8 -loglevel debug

  The client :

  <code class="echappe-js">&lt;script src=&quot;https://cdnjs.cloudflare.com/ajax/libs/hls.js/0.10.1/hls.light.min.js&quot;&gt;&lt;/script&gt;
  &lt;script src=&quot;https://releases.flowplayer.org/7.2.6/flowplayer.min.js&quot;&gt;&lt;/script&gt;
  
  &lt;script&gt;<br />
  
          flowplayer('#player', {<br />
  
              live: true,  // set if it's a live stream          <br />
  
              ratio: 9/16, // set the aspect ratio of the stream<br />
  
              clip: {<br />
  
                  sources: [<br />
  
                      // path to the HLS m3u8<br />
  
                      { type: &quot;application/x-mpegurl&quot;, src: &quot;&amp;lt;?php echo asset_url();?&gt;video/test.m3u8&quot;},<br />
  
                      // path to an optional MP4 fallback<br />
  
                      { type: &quot;video/mp4&quot;, src: &quot;//yourserver/path/index.mp4&quot;}<br />
  
                  ]<br />
  
              }<br />
  
          });<br />
  
  &lt;/script&gt;
  
  

  The problem ? dont show video in "Live", only show 20seconds aprox and the video is loop icon loading

  what am I doing wrong ? I try it all night but I think that it reaches the point of not finding the right path

  thanks for your time !
