I am running my Overo Air (Linux overo 2.6.29-omap1 #1 Wed Apr 15
08:54:49 EEST 2009 armv7l GNU/Linux) with shell script, handling audio
encoding with following (in loop):
arecord -f cd -r 16000 -d 1200 |flac - -o out-$count.flac
Somehow this always ends up on total freeze of whole system! Recording
plain wav to micro sd works just fine. But when ever I add either Flac
or Speex encoding on the chain, overo cannot handle it.
Load cannot be issue, since top shows less than 1 for average and long I
thought it could be something with ext3 performance on microsd, but
recording wav files to sd works like a charm.
Since I've compiled my kernel all by myself, I wonder should I include
flac and speex also to that build. Now I've downloaded them with opkg.
