Part Number: AM62A7
We run GStreamer pipeline on TI AM62A7 platform.
The pipeline consists of v4l2src, tiovxisp, v4l2h264enc, h264parse, rtspclientsink.
Under input resolution 3840×2160, 30fps, the stable frame rate can reach 28fps.
Once we insert tiovxldc or tiovxmultiscaler after tiovxisp, the frame rate drops sharply to 17fps.
We suspect there are performance bottlenecks within the TIOVX hardware acceleration module.
Please help analyze the possible causes.
Attached are the complete pipeline commands for reference.
