• building ffmpeg 2.1.8 with MSVC2013 (configure produces errors)

  29 juin 2017, par scaram

  I am trying to build ffmpeg 2.1.8 for a legacy project. I use windows 10, MSVC 2013, MSYS, YASM and this tutorial.

  After

  ./configure --toolchain=msvc --enable-shared

  I see the many errors in config.log, here the first three ones

  1. error : ’test’ declared as an array with a negative size
  2. fatal error C1189 : #error : "unsatisfied condition : defined GLIBC"
  3. fatal error C1083 : File (Include) cannot be opened : "newlib.h" : No such file or directory

  here the more detailed information...

• VLC RTSP HTML5 transcoding

  30 mai 2022, par Pierogi

  I'm trying to get audio streaming on an HTML page from an RTSP server.

  


  The RTSP server is the rtsp-simple-server running a command line below.
  
./rtsp-simple-server rtsp-simple-server.yml.
  
The configure file is the default.

  


  The stream player is FFmpeg running a command line below.
  
ffmpeg -re -stream_loop -1 -i myaudio.mp3 -c copy -f rtsp -rtsp_transport tcp rtsp://localhost:8554/mystream

  


  The console log at the time the rtsp-simple-server and the ffmpeg are started is below.

  


  2022/05/29 19:06:38 INF rtsp-simple-server v0.18.4
2022/05/29 19:06:38 INF [RTSP] listener opened on :8554 (TCP), :8000 (UDP/RTP), :8001 (UDP/RTCP)

2022/05/29 19:09:16 INF [RTSP] [session 271690815] is publishing to path 'mystream', 1 track with TCP


  


  And the time the rtsp path(rtsp ://localhost:8554/mystream) is opened by VLC, the contents can be played properly. The additional console log at the time is below.

  


  2022/05/29 19:13:19 INF [RTSP] [conn 127.0.0.1:62780] opened
2022/05/29 19:13:19 INF [RTSP] [session 734209460] created by 127.0.0.1:62780

2022/05/29 19:13:29 INF [RTSP] [session 445756113] is reading from path 'mystream', 1 track with TCP


  


  However, I open the rtsp streaming from the VLC's "Network" tab like below,


  


  and configure the "Stream output" like below,


  


  and I tried to get this streaming from an HTML page like below,

  


  &#xA;&#xA;  &#xA;    &#xA;    &#xA;  &#xA;  &#xA;    <h1>transcode test</h1>&#xA;    <audio src="http://localhost:9999/mystream" autoplay="autoplay"></audio>&#xA;  &#xA;&#xA;

  


  the browser console displays Failed to load resource: the server responded with a status of 404 (Not found). I've already tried other ports(etc. 8080).

  


  So, how can I get the rtsp stream from the RTSP server on an HTML page.
Any idea ?

  


  My environment.

  


  

  • Browser : Microsoft edge

  


  • OS : MacOS 11.6.5

  


  • rtsp-simple-server : 0.18.4

  


  • FFmpeg : 5.0.1

  


  • VLC : 3.0.17.3

  


  


• Flutter FFMPEG : Error setting profile baseline

  9 avril 2021, par Raj Dhakad

  Flutter-ffmpeg unable to set profile parameter. (I need to use profile so the rendered video can be played on WhatsApp).

  


  I am converting.bmp images into a mp4 video. Other I have tested other praramets and the work great it's only -profile:v which seems to have some problem.

  


  Everything works fine unless I use -profile:v baseline.

  


  void _runFFmpeg() async {
    var dir = await getApplicationDocumentsDirectory();
    var output = await getExternalStorageDirectory();
    String videoSize = '${ImageWidth}x$ImageSize';
    print("${ImageWidth}x$ImageSize");
    var arguments = [
      "-y", // replace output file if it already exists
      "-framerate", "30", // framrate
      "-video_size", videoSize,
      "-pixel_format", "yuv420p",
      "-i", "${output.path}/frame_%d.bmp",  
      "-profile:v", "baseline",
      "-level", "3.0",
      "${output.path}/test.mp4"
    ];
    
    _flutterFFmpeg
        .executeWithArguments(arguments)
        .then((rc) => print("FFmpeg process exited with rc $rc"));
 

    print("Done Rendering");
  }
