• Video recording solution for angular and spring boot app [closed]

  24 juin 2022, par Shinu Mathew

  I am trying to build an app with angular on the front end which should be able to record video using users webcam and send data to a spring boot backend microservice in parts. I have tried using client libraries like video-recordjs but I face a lot of issues when it comes to cross platform and devices. I am looking for a reliable solution which would help me to accomplish this and work well on all browsers and devices. Any suggestion or help would really be appreciated.

  


• avformat/matroskaenc : Don't waste bytes to Write Tag length fields

  15 juin 2022, par Andreas Rheinhardt

  avformat/matroskaenc : Don't waste bytes to Write Tag length fields
  This is possible by using a dynamic buffer to write them ;
  
  said dynamic buffer is (re)used and reset as appropriate.

• nodejs aws lambda ffmpeg command failure

  14 juin 2022, par mozenge

  Im running an ffmpeg command to generate a thumbnail from a video that exists on aws s3 bucket but accessed from cloud front. So i try to stream the video in the command. This is implemented in nodejs and the ffmpeg dependency is a lambda layer. The code looks like so

  


  const gifName = `${baseFilename}.gif`;
await execPromise(`ffmpeg -t 10 -ss 00:00:01 -i "${_url}" ${'/tmp/' + gifName}`);


  


  _url is a clound front url. This works when i test locally even via aws SAM cli.
But this fails when testing the deployed fuction. The error output I get is as follows
