1 month ago run with --encoder=mpp --resolution=1920x1080 in gdb and unpluged the hdmi streamer will create two New Threads LWP 18387(us_mpp_jpeg_encoder_init in encoder.c) and LWP 18388(worker pool),but it only destoryed LWP 18388 Thread when ERROR ,and it will increase the memory usage about 16M in each polling.

1 month ago Inappropriate ioctl for device is not the keypoint that is caused by unpluged the HDMI cable or HDMI no signal ,the keyponit is memory leaking in that situation.
if (type == US_ENCODER_TYPE_MPP) {
US_LOG_INFO("Switching to MPP encoder ...");
_ER(mpp) = us_mpp_jpeg_encoder_init(dev->width, dev->height, MPP_FMT_YUV422_UYVY, 30, quality);
n_workers = 1;
}
when I changed the config "forever:false" and comment "--persistent" in override.yaml to let streamer poll the states all time, It works well before hdmi-in unpluged or no signal,when hdmi has no signal or unpluged for few minutes the kvmd will crush and restart, there are some OOM mesesages in kernel log
