Problem Description

The videoDecodeRGB sample application will frequently give different outputs for the same input stream.
For example, given the HEVC Conformance stream AMP_A_Samsung_4.bit is input with -of (output format) set to RGB, the output stream will might have frames that are out of order at some point in the stream. Currently this occurs towards the end of the stream.

Operating System

Ubuntu 22.04.3 LTS

CPU

AMD Ryzen 7 3800X 8-core processor x16

GPU

AMD Radeon RX 7900 XT

ROCm Version

ROCm 6.2.0

ROCm Component

No response

Steps to Reproduce

To reproduce:
./videodecodergb -i AMP_A_Samsung_4.bit -o AMP_A_Samsung_4.rgb -of rgb -md5
Save this first output stream and check the md5 given.
Run the same command again but change the name of the output stream to AMP_A_Samsung_4_2.bit and run until a different md5 is given.
Playback both streams in YUView and see that one will play correctly while the other will play with some stuttering due to frames being out of order.
This is only one example stream where this occurs.
Another stream where this has been seen is: AMP_B_Samsung_4.bit
From all of the tests run, this does not seem to be stream dependent and can happen with any input streams.
