• Building a livestream page where the user will input an rtsp streaming source through an ip address

  7 décembre 2020, par Antax Md

  I am building a livestream page where the streaming source is streamed through rtsp. Currently, I am using ffmpeg to convert the incoming rtsp stream to a .m3u8 file and it is played back on the webpage through HLS.

  


  The problem i am trying to solve now, is loading an rtsp stream based on the user's input. How do i go about solving this ? It is a requirement to able to view the stream on iOS and android.
The ffmpeg command :

  


  ffmpeg -i "rtsp://10.193.79.185:5554" -hls_time 3 -hls_wrap 10 "C:\wamp64\www\hls\output.m3u8"


  


  Code of what I have at the moment that loads a hard coded rtsp stream

  


  &#xA;&#xA;  &#xA;      <code class="echappe-js">&lt;script src=&quot;https://cdn.jsdelivr.net/npm/hls.js@latest&quot;&gt;&lt;/script&gt;&#xA;      &#xA;          
  RTSP Stream
  &#xA;                &#xA;                &#xA;
  Start
  &#xA;                &#xA;
  
  &#xA;      &#xA;&#xA;      &lt;script&gt;&amp;#xA;        if(Hls.isSupported()) &amp;#xA;        {&amp;#xA;            var video = document.getElementById(&amp;#x27;video&amp;#x27;);&amp;#xA;            var mystring = &quot;http://192.168.43.79/hls/output.m3u8&quot;;&amp;#xA;            var hls = new Hls({&amp;#xA;              debug: true&amp;#xA;            });&amp;#xA;            hls.loadSource(mystring);&amp;#xA;            hls.attachMedia(video);&amp;#xA;            hls.on(Hls.Events.MEDIA_ATTACHED, function() {&amp;#xA;            video.muted = true;&amp;#xA;            video.play();&amp;#xA;        });&amp;#xA;        }&amp;#xA;        // hls.js is not supported on platforms that do not have Media Source Extensions (MSE) enabled.&amp;#xA;        // When the browser has built-in HLS support (check using `canPlayType`), we can provide an HLS manifest (i.e. .m3u8 URL) directly to the video element throught the `src` property.&amp;#xA;        // This is using the built-in support of the plain video element, without using hls.js.&amp;#xA;        else if (video.canPlayType(&amp;#x27;application/vnd.apple.mpegurl&amp;#x27;)) {&amp;#xA;            video.src = &amp;#x27;http://192.168.43.79/hls/output.m3u8&amp;#x27;;&amp;#xA;            video.addEventListener(&amp;#x27;canplay&amp;#x27;,function() {&amp;#xA;            video.play();&amp;#xA;          });&amp;#xA;        }&amp;#xA;      &lt;/script&gt;&#xA;  &#xA;&#xA;
  

  


• Visual Studio & ffmpeg : Building FFmpeg in visual studio - 'ffmpeg.obj'

  11 mai 2021, par Simba_cl25

  I am new here and I am trying to link ffmpeg with visual studio following some guides like :

  


  

  • http://ffmpeg.org/platform.html#Linking-to-FFmpeg-with-Microsoft-Visual-C_002b_002b

  


  


  I added librairies in the project propreties :

  


  

  • In C/C++ —> General —> Additional Include Directories

  


  • In Linker —> General —> Additional Library Directories

  


  • In Linker —> Input —> Additional Dependencies

  


  


  But I have encountered the following problem :

  


  


  Error LNK1104 cannot open file 'ffmpeg.obj'

  


  


  I tried to add double quotes around path of the libraries but it hasn't changed the outcome.

  


  Nevertheless, I can't find anything about 'ffmpeg.obj'
What is this file ? What could I change to avoid this error ?

  


• Building ffmpeg libraries on windows

  18 juin 2021, par MisterSincere

  I am trying to compile ffmpeg library files (static preferred) for windows. I tried to use the msvc toolchain from within msys2, but configure always came back with an error related to cl.exe not being able to compile a test program. The most progress I made by using msys2 with mingw-w64-gcc, but from here on I've only generated executables, but no library files. I tried different configure options (i always use --enable-cross-compile).

  


  First I read that static is default and not shared, but the result of make was no lib file at all, just again the executable. So I additionally passed --enable-static, which also made no difference. Then I tried --enable-gpl, because it is an option that was used for the NvDecode-Sample's pre-built ffmpeg libraries (which I currently use, but they do not include all the features I wanna use).

  


  I also tried completely different ways like using npm : npm install ffmpeg-static, which gave me again just an executable.
Or the release page with prebuilt libraries from a github project here, but these gave me weird behaviour, that I will only go into if asked, since this is not the main topic of this question.
