[ScorpiosCrux]

Setup

• RK3588
• kernel: 5.10.160
• H265 decoder
• GStreamer Video Player
• Android 12

Issue

When using the RK H265 decoder with GStreamer, an RTSP stream that changes resolution will throw the following error infinitely and the images becomes blurry. This issue does not occur with the H264 decoder.

How to reproduce:

• RTSP stream
• Play video at 1080p on the client
• Change the stream from 1080p to a different resolution without closing the client stream
• Video becomes blurry and does not recover.

Other notes

• This issue does not occur using the H264 decoder.
• Sometimes you need to reinitialize GStreamer again.

Let me know if you need more help with reproducing this.
