OOM message comes in dmesg when textoverlay is used to play subtitle

[Ikshwaku Chauhan]

Dear All,

we are facing issues when we try to play (DIVX/MP4 + external
subtitle)videos.
When we try to play the video + external subtitle video freezes after
sometime(duration is not fixed) and we get following dmesg logs for oom

sin invoked oom-killer: gfp_mask=0x24200c4, order=0, oom_score_adj=0
[  402.227471] [<c0168538>] (dump_header) from [<c011838c>]
(oom_kill_process+0x308/0x454)
[  402.227529] [<c0118084>] (oom_kill_process) from [<c011884c>]
(out_of_memory+0x2fc/0x338)

swapents oom_score_adj name
[  403.774826] oom_kill_process: 10 callbacks suppressed

Also, when we check LowFree in cat /proc/meminfo, it is dropping
significantly. Generally video freezes when LowFree comes down to around 10
MB.

when we play videos without subtitle, video playbacks without any issue.

we are using gstreamer plugin version 1.6.3 with wayland based video sink
on Ti's SOC.

Does anyone knows about this issue or could you please help us in debugging
this issue further?

Thanks in advance.

Regards,
Ikshwaku
