• checkasm/riscv : preserve T1 whilst calling...

  29 juillet 2024, par Rémi Denis-Courmont

  checkasm/riscv : preserve T1 whilst calling...
  This preserves T1 whilst calling the instrumented function. In a Sci-Fi
  
  setting where type-based Control Flow Integrity (CFI) is supported, the
  
  calling code (i.e., the `checkasm` test case) will set T1 to the expected
  
  value of the landing pad label (LPL) of the instrumented function.
  The call wrapper will always use LPL zero which is a wild card. We should
  
  preserve the value of T1 at least until the indirect call to the
  
  instrumented function. Of course this is Sci-Fi, because :
  
  1) there is no hardware (or even QEMU) support yet,
  
  2) all our assembler functions currently use LPL zero anyway.
  This uses T3 rather than T2 because indirect branches with T2 is reserved
  
  for notionally direct calls made with an indirect call instruction (e.g.
  
  due to GOT indirection), and are exempted from forward-edge CFI checks.

• ffmpeg takes screenshots all at once

  19 décembre 2020, par oo92

  I am trying to use ffmpeg to grab screenshots of twitch streams. This is my command :

  


  ffmpeg -i https://stream-link.m3u8 
-ss 30 
-frames:v 10 
-r 1
-f 
image2 
/home/me/Desktop/images/image-dataset/my-dataset/World-of-Warcraft/filename.jpg&


  


  My goal is to take 1 screenshot per second for a total of 10 screenshots. I've added the & at the end of the filename.jpg to take these screenshots concurrently. However, the screenshots I get are all the same thing. No difference. The exact spitting moment in all 10 images. My take is that ffmpeg is not listening to -frames:v 10 and instead takes 10 screenshots all at once.

  


  I tried to run it sequentially and the same problem happened. So the issue isn't concurrency..

  


  Is there a way I can fix this ?

  


  Output :

• Firefox does not support mkv format videos, need to convert video to mp4

  21 mai 2021, par sambhav jain

  I am making a screen recorder app that records your screen and upload the video to the s3 bucket. the video is in mpv format. the mkv format is supported by chrome, edge but not by firefox. Firefox supports the mp4 format. so how do I convert the video to mp4 format for firefox ? videofile is in mkv which needs to be converted to mp4

  


  handleUpload() {
    for (let i = 0; i < this.files.length; i++) {
      this.awsUploadService
        .getSignedUrlS3(this.files[i]["name"], this.files[i]["type"])
        .subscribe(
          ({ url, keyFile }) => {
            this.awsUploadService
              .uploadfileAWSS3(url, this.files[i]["type"], this.files[i])
              .subscribe(
                (data) => {
                  if (data["type"] === 1) {
                    this.files[i]["progress"] =
                      (data["loaded"] / data["total"]) * 100;
                  }
                  if (data["type"] === 4) {
                    this.files[i]["isUploadCompleted"] = true;
                    this.files[i][
                      "uploadLocation"
                    ] = `https://${environment.S3_BUCKET_NAME}.s3.${environment.S3_Region}.amazonaws.com/${keyFile}`;
                  }
                },
                (error) => {
                  this.files[i].isUploadCompleted = false;
                  throw error;
                }
              );
          },
          (error) => {
            this.files[i].isUploadCompleted = false;
            throw error;
