标题: mppjpegdec解码60fps的1920*1080图像
请问gstreamer的mppjpegdec可以解码60fps的1920*1080图像吗？
我使用这个gstreamer管道：
v4l2src device=/dev/video21 do-timestamp=true min-buffers=60 ! queue leaky=2 max-size-buffers=60 ! image/jpeg,width=1920,height=1080,framerate=60/1 ! queue leaky=2 max-size-buffers=60 ! mppjpegdec ! queue leaky=2 max-size-buffers=5 ! clockoverlay font-desc=\"Sans,8\" time-format=\"%Y-%m-%d %H:%M:%S\" ! queue leaky=2 max-size-buffers=5 ! textoverlay font-desc=\"Sans,8\" text=测试 valignment=1 halignment=2 ! queue leaky=2 max-size-buffers=5 ! appsink name=appsink emit-signals=true sync=false max-buffers=2 drop=true
管道开始运行时，输出警告：
0:00:00.179174933 332191    0x3fc8e920 WARN       v4l2bufferpool gstv4l2bufferpool.c:809:gst_v4l2_buffer_pool_start:<v4l2src0:pool:src> Uncertain or not enough buffers, enabling copy threshold

运行半小时后，数据中断：
