Problem in audio syncing in FLV video

Jul 27, 2016


I am facing an issue related to audio-syncing in FLV videos. When we import an FLV video in a project, the published output works fine locally. 

But when we upload it online on LMS, the audio gets out-of-sync. Sometimes, the audio gets paused in between but the video keeps on playing.

Also, the video keeps on playing after the timeline is finished.

I am converting a MP4 video into FLV with Adobe Media Encoder with the following settings:

  • Codec: On2 VP6
  • with Alpha Channel
  • Frame Rate: Same as source
  • Bitrate Encoding: VBR
  • Encoding Passes: Two
  • Bitrate Level: High


Has someone faced this similar issue?

Is there any work around for this?
