Thank You.
I had followed the QNX_Aviage_Introduction_MME.pdf doc as below and tried to play .wav file using "mmecli" on QNX target.But "mmecli play" is giving errno=61 and sometimes errno=21.
I had copied "adr.wav" file to "/media/drive/" folder and manually entered the entry to QDB database to "LIBRARY" table.

# io-fs-media -d tmp -cpages=4 -cbundles=0
# qdb -c /db/qdb.cfg -v -Otempstore=/fs/tmpfs -Rset
#mcd /etc/mcd.conf
# io-media-generic -M mmf,dlldir=$QNX_TARGET/x86/lib/dll/mmedia
#mme-generic -c /etc/mme.conf
# mmecli newtrksession l "select fid from library where ftype !=5"
(rc=0,errno=0) new trksessionid=1. Execution Time=0.038
# mmecli settrksession 1
(rc=0,errno=0) Set trksessionid=1. Execution Time=0.063
# mmecli play
(rc=-1,errno=61) Playing from tracksession fid/bid = 0. Execution Time=0.012

I feel iam not configuring the database tables correctly.Is there any sample program to update the database tabes.
Iam having below additional query
1.When the MME database tables like MEDIASTORES,LIBRARY,SLOTS etc will be updated when any media source is inserted?Do we have to manually enter the tables or MME itself will update it?
