Massif output
I generated 1 hour test mp3 files with a 440 sine, at 32,64, and 128kbps. Using
valgrind massif, I can see a steady increase in memory consumption. The
gst-launch line is:
valgrind --tool=massif --massif-out-file=memleak-128kbps.massif
gst-launch-0.10 filesrc location=sine-128kbps-48khz-stereo-1hour.mp3 !
mpegaudioparse ! fakesink
The line for creating the test files is:
gst-launch-0.10 audiotestsrc samplesperbuffer=48000 num-buffers=3600
wave=sine ! \
"audio/x-raw-int, rate=(int)48000, channels=(int)2" ! lame bitrate=128 ! \
filesink location=sine-128kbps-48khz-stereo-1hour.mp3
Using ms_print to visualize the results, I see a linear increase from initially
1.95 MB to 4.11 MB.
The massif and ms_print outputs are attached.
