vlc 1.1.3 on mips platform got oom-killer

[zhangtower]

i cross compile vlc on mips platform, when i input the command
vlc --sout '#udp{dst=225.1.1.40,port=1234}' /mnt/media/default.mpg
vlc runs very slowly, after 2-3 miniutes, omm-killer will occur.
the console print the following information.

when i input top command in another console, i found the cpu's io load is very heavy.
vlc 0.8.6i does not show this error, the upper version show it,
does vlc upper 0.8.6i on mips has memery leak problem?
anyone know how to solve it?

[Rémi Denis-Courmont]

Kernel debug is totally useless to investigate memory leaks in VLC. The recommended method consists of running the 'massif' tool from valgrind.

That said, it seems your device has quite little memory (128 Mb?). This might simply not be enough.

[zhangtower]

i will try the 'massif' tool.
but i don't know why the io load is so heavy and vlc-0.8.6i is not? has the ts mux Algorithm changed？
BYT, the memory of my device is 256M, is it enough?
