[Bug]: HDR Decode Issues - Kodi/FFMpeg and Arc A380 about media-driver HOT 3 OPEN

ffmpeg log shows some inputs wrong sending to media driver. According to your description, it always decodes well with native bitstream, but only fails with online inputstream, so please check if application sends incompleted bitstream data to media driver.

Capture the libva trace log for both native bitstream and online bitstream firstly, then we can have some initial analysis:
mkdir -p /home/trace
export LIBVA_TRACE=/home/trace/file
export LIBVA_TRACE_BUFDATA=1

If possible, use debug version media driver and capture some driver logs as well.
mkdir -p /data/driver_dump
put bellow config in /etc/igfx_user_feature_next.txt

[config]
Codec Message Tags=7
DDI Message Tags=7
Message HLT Enabled=1
Message HLT Output Directory=/data/driver_dump
Message Print Enabled=1
Mhw Message Tags=4
Mos Message Tags=4
