• The YouTube live stream encountered a failure

  12 février 2024, par kuldeep chopra

  We are currently utilizing the ffmpeg library for streaming on YouTube Live. However, we have faced issues in a recent live streaming session that initially functioned correctly but encountered errors around the 13 to 15-minute mark. The error logs from FFmpeg during this session are as follows :

  


  Live Stream 1 Error :(Attempt 1)

  


  


  ffmpeg [flv @ 0x555c4bdfe680] Failed to update header with correct

  Live Stream 2 Error (Attempt 2) :

  


  


  Slave muxer #1 failed : Connection reset by peer, continuing with 1/2

  It is crucial to note that we have conducted numerous live streams on YouTube without encountering this error previously ; this is the first instance of such an issue.

  


  We kindly request your assistance in investigating and providing insights into the underlying problem causing these error messages. Any guidance or support you can offer in resolving this issue would be greatly appreciated.

  


• I need to implement video compression for files that exceed 5 MB in size

  27 septembre 2024, par KAVYA P

  I need to implement video compression for files that exceed 5 MB in size. I have tried several packages for this purpose, but they either do not work as expected or have significant security vulnerabilities. It's crucial for me to find a reliable and secure solution for compressing videos that meet this file size requirement. If you have any recommendations for libraries or tools that effectively handle video compression without compromising security, please let me know.

  


   const handleFileChange = async (&#xA;    event: React.ChangeEvent<htmlinputelement>&#xA;  ) => {&#xA;    const file = event.target.files?.[0];&#xA;    if (file) {&#xA;      const isImage = file.type.startsWith(&#x27;image/&#x27;);&#xA;      const MAX_FILE_SIZE = isImage ? 2 * 1024 * 1024 : 5 * 1024 * 1024; // 2 MB for images, 5 MB for videos&#xA;&#xA;      if (file.size > MAX_FILE_SIZE) {&#xA;        if (isImage) {&#xA;          alert(&#x27;Image file size exceeds 2 MB. Compressing the file...&#x27;);&#xA;          try {&#xA;            const compressedFile = await imageCompression(file, {&#xA;              maxSizeMB: 2,&#xA;              maxWidthOrHeight: 1920,&#xA;              useWebWorker: true,&#xA;            });&#xA;            onSelectFile({&#xA;              ...event,&#xA;              target: {&#xA;                ...event.target,&#xA;                files: [compressedFile] as unknown as FileList,&#xA;              },&#xA;            });&#xA;          } catch (error) {&#xA;            console.error(&#x27;Error compressing the image:&#x27;, error);&#xA;          }&#xA;        } else {&#xA;          alert(&#x27;Video file size exceeds 5 MB. Please choose a smaller video.&#x27;);&#xA;        }&#xA;      } else {&#xA;        onSelectFile(event); // Proceed with the file selection&#xA;      }&#xA;    }&#xA;  };&#xA;</htmlinputelement>

  


• How to use prebuilt FFmpeg in Android Studio

  26 mai 2016, par vxh.viet

  I’m sure this is a very basic question but since this is the my first time messing around with the NDK, a lot of thing is still very unclear to me.

  Use case :

  • I’m trying to develop a video scrubbing feature so fast and accurate frame seeking is crucial. I’ve tried most of the available players out there but the performance is still not up to my demand. That’s why I’m going down the FFmpeg route.

  • Basically, what I’m looking for is FFmpeg input seeking. I’ve tried WrtingMinds’ ffmpeg-android-java. However it is a file based implementation which means the out.jpg need to be written to external memory and read back which has a big hit on performance (roughly 1000 milliseconds for 1 seek).

  • That’s why I’m trying to built my own FFmpeg player to do the input seeking in JNI and push back the byte[] to be displayed in Java.

  Question : After a lot of struggling with the NDK, I’ve managed to set it up and successfully calling the JNI method from my Java code. The structure is as below :

  MyApp
  
    -app
  
    -MyFFmpegPlayer
  
      -build
  
      -libs
  
      -src
  
        -main
  
          -java
  
            -com.example.myffmpegplayer
  
              +HelloJNI.java
  
          -jni
  
            +MyFFmpegPlayer.c

  After some fail attempt to build FFmpeg on Windows, I’ve decided to use WritingMinds prebuilt FFmpeg. However, after extraction they just come up as plain ffmpeg files (not .so file) so I don’t really know how to use these.

  It would be a great gratitude, if someone can just chime in and give me a good starting point for my next step.

  Thank you so much for your time.
