<div>What are you seeing?
Any log errors? I have
a laptop with hybrid
GFX. Nvidia and Intel,
so I can launch
mythfrontend with pure
Nvidia or pure Intel.
Since I've been told
that using OpenGL only
works best with the
current software and
average CPU. That even
applies to RPI 4. I'm on
v35 on everything so I
can test it.</div>

<div>I did a quick test on my
laptop and launched
mythfrontend with dedicated
GPU option. NVDEC would not
even play for me. I switched
to OpenGL High Quality and it
played perfectly. Of course my
laptop is pretty good. Intel©
Core™ i7-10750H CPU @ 2.60GHz

<div>Thanks for confirming you see the same
issue. Yes, other decoders work (VDPAU,
FFMPEG, etc.). But my CPU is not powerful
enough for h.265 HEVC 4K decode. That is
why I need Nvidia NVDEC. Hopefully the
issue is fixed soon.</div>

What Nvidia driver version do you have?<br>
<br>
When I updated FFmpeg to 7.1, I had to update ffnvcodec (the headers
FFmpeg uses for dynamically loading CUDA/NVDEC/NVENC), which
increased the minimum driver version to 550. There are other
versions of ffnvcodec we could use with lower driver version
requirements. See <a class="moz-txt-link-freetext" href="https://github.com/MythTV/mythtv/pull/1040">https://github.com/MythTV/mythtv/pull/1040</a> if
that is the issue.<br>
<br>
