With the recent FireOS 184.108.40.206 update, playback stutters after switching to a track that has different frame rate than the previous one.
Steps to reproduce
1. Play a H264 HLS Live content at 480p 30fps, (DRM Protected - HW secure decoder should be in use.)
2. Change track to 1080p 50fps
3. Playback starts to freeze but audio works fine.
Device: Fire Stick 4K 1st Gen (model AFTMM)
This doesn't happen with FireOS 220.127.116.11.
We believe Secure HW Decoder is not re-initialised when switching to different frame rate and causing this problem. We can provide more details and a sample content about the problem if needed through a private channel.
