On MVL 2.6.18, I ran TI's decode demo playing "The DaVinci effect" on
DM6446 EVM.  While the video/audio is playing, I also record using
arecord (at 48000 sample rate).  I did not noticed any glitches in the
entire video.  For this test, I read/write files from the hard disk.

I also tested the decode demo with audio/video files from NFS.  I
observed glitches.  The problem was traced to data alignment issue in
the EMAC driver.  Once the alignment problem was addressed, I did not
observe any issues.  The alignment patch is available at MV zone.

When you observed stalls, does not recover or you have to reboot?  Also,
how often does it happen?

Regards,

Steve
