I run "gplay -r 1.7.mov maiken1.mpg 00004.mov weiduolila.mp4"  to play some videos by circle.  It plays well at first, but after about 10 hours, gplay falls into TASK_INTERRUPTIBLE stat and never wake up again. gplay indicate he is playing but actually he is stop.gplay shows some information as follow:

It happens to me several times, If I ony run "gplay -r  00004.mov", gplay can run more than one day.It seems playing one video is  well.

 

But the way,my kernel is 3.0.35. And I have patched some patches to my kernel:

1. patch_v4l2_issue.zip( GStreamer crashing on i.MX6 (Boundary Devices Nitrogen6x)),and I add [system("echo 3 > /proc/sys/vm/drop_caches")] to gplay before playing a new video.

2. 0009-ARM-imx-return-zero-in-case-next-event-gets-a-large-.patch \ 0026-ENGR00306257-1027-fix-system-hang-up-issue-caused-by.patch.txt

 

Can anyone give me some advise?

 

Thanks

Xiaoming
