• FFMPEG on MACOSX is complaining "no matches found"

  15 juin 2022, par Byte Player

  I have a FFMPEG command line function that works perfectly on Windows but on Mac produces the following error :

  


  "no matches found [1:a]adelay=15000:all=1[aud2]"
  
"no matches found [2:a]adelay=5000:all=1[aud3]"

  


  Here is the command (less the full paths which just made it very hard to read). I've verified that the files exist at the paths specified by copying the file path from the command line and going into terminal, typing "open" then pasting in the copied path and pressing enter. In all cases they played.

  


  ffmpeg -loglevel warning -hide_banner -y -i "file1.mp3" -t 5 -i "file2.mp3" -i "file3.mp3" -i "file4.mp3" -ss 25 -t 15 -i "file5.mp3" -ss 15 -t 5 -i "file6.mp3" -filter_complex [1:a]adelay=15000:all=1[aud1];[2:a]adelay=5000:all=1[aud2];[4:a]adelay=25000:all=1[aud4];[5:a]adelay=5000:all=1[aud5];[aud1][aud2][aud4][aud5]amix=inputs=6:duration=longest:dropout_transition=0:normalize=0 "output.mp3"


  


  I know the immediate response (as it should be), is update your FFMPEG but I got the latest build (built on 2022-06-12) and here's what it reports...

• How can I convert a mp4 file to webm using java only ?

  31 octobre 2023, par mir-shakir

  I am trying to convert a file from mp4 to webm. I am trying to use the JAVE wrapper of FFmpeg. I am getting the error.
Here is my code :

  


  private String ConvertVideo(URL url) {
    File target =null;
    MultimediaObject multimediaObject = new MultimediaObject(url);
    try {
        target = File.createTempFile("target", ".webm");

    } catch (IOException e1) {
        e1.printStackTrace();
    }
    AudioAttributes audio = new AudioAttributes();
    audio.setCodec(AudioAttributes.DIRECT_STREAM_COPY);
    audio.setBitRate(new Integer(128000));
    audio.setSamplingRate(new Integer(44100));
    audio.setChannels(new Integer(2));
    VideoAttributes video = new VideoAttributes();
    video.setBitRate(new Integer(160000));
    video.setFrameRate(new Integer(15));
    video.setCodec("libvpx-vp9");
    video.setCodec(VideoAttributes.DIRECT_STREAM_COPY);
    EncodingAttributes attrs = new EncodingAttributes();
    attrs.setFormat("webm");
    attrs.setAudioAttributes(audio);
    attrs.setVideoAttributes(video);
    
    try {
          Encoder encoder = new Encoder();  
          encoder.encode(multimediaObject, target, attrs);
        } catch (Exception e) {  
           e.printStackTrace();
        }
    
    return "success";
}


  


  I am getting the below error :

  


  2022-Jun-13 11:12:55 AM [qtp1914526580-175] ERROR ws.schild.jave.Encoder - Process exit code: 1  to target2636257785060285182.webm
ws.schild.jave.EncoderException: Exit code of ffmpeg encoding run is 1


  


  What am I doing wrong here. Is there any other way around it ? I want to do it only using java.

  


• 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.
