Stuttering Dash DRM livestreaming video on WebOS 3.x

Hello WebOS community, we are facing a stuttering problem when streaming Dash DRM. We have found that this stuttering issue only occurs on WebOS 3.x, which is from LG 2017. I have also asked the Shaka Player contributors, but they suggested asking the webOS Community because they have limited device resources (Stuttering Dash DRM livestreaming video on WebOS 3.x · Issue #6321 · shaka-project/shaka-player · GitHub).

Here is the information about the livestreaming:

  • Dash manifest, DRM
  • Video codecs: avc1.64081f
  • Audio codecs: mp4a.40.2
  • Segment format: m4s

this stuttering issue only happen after 1-2 seconds playing
