Unknown memory blocks in gstreamer runtime memory map

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Hi,

I'm running GStreamer, built with CodeSourcery arm toolchain [version:
(CodeSourcery Sourcery G++ Lite 2007q3-51) 4.2.1], on TI's OMAP board.
The runtime memory consumption (as reported by 'top' command) is 38% on a
128MB RAM (~48MBytes), which is very high. Verifying the memory map log
(using pmap), I found the presence of some un-named memory blocks of size
8188 KBytes which contributes major share to the 38% RAM usage (PMAP log
attached). Is this a GStreamer bug or a memory leak? Can anyone help me to
fix this?

Currently I'm using the mp3 playback with the following pipeline
*$gst-launch filesrc location=test.mp3 ! queue ! mad ! alsasink*
**
Any help on this is highly appreciated.

Thank you,
Gireesh
