Hi,need your help again,
In the compound below where the 4K video is selected as the input source, there is playback stuttering, but it plays smoothly in the SE project. For settings, please refer to the attached image. Do you have any suggestions, or is it an issue with the settings?
The video source plays normally in the player, and the parameters are as shown in the figure.
Best wishes.
Hi,
Indeed, the setting "use GPU when decoding H.264 and H.265" plays a significant role if you're working with video playback in H.264 or H.265 formats.
When activated, this GPU decoding function is not directly visible within Aximmetry's ProcessLoad GPU meter. This is because GPU video decoding is a separate process within the GPU to some degree. Nonetheless, you can monitor this specific load through Windows's Task Manager. Navigate to Task Manager's Performance > GPU > Video Decode to assess the impact:
When the "Use GPU when decoding H.264 and H.265" setting is turned off, the CPU decodes the video. Sadly, this is also not fully visible on the ProcessLoad panel in some cases.
Regardless of whether the GPU or CPU handles the decoding, a video with a bitrate of 80,000 kbps can impose a considerable load on the hardware. Additionally, Unreal Engine can significantly tax both the GPU and CPU.
If the shuttering is not constant, then you might be able to fix it by increasing the Buffered frames of the Video Player module:
Warmest regards,
What GPU/CPU load are you seeing?
