Troubleshooting

Q. How can I tell when a file has finished playing?
A. The HDCom application reports callback message 2 (Playback
Complete) to indicate when a file has finished playing.
However, this callback message will not be sent if the channel
is in automatic loop mode, or if the mpgLoadNext command
has been issued. In addition, the HDCom application may not
report this callback message until 1–2 seconds after the file has
actually finished playing.
Q. Sometimes files “block” or “pixelize” when looping back to
back. How can I correct this?
A. There are two ways that the driver can transition files when
looping. One way attempts a “smooth” transition, in which it
starts the beginning of the file immediately after detecting the
end of the file. This is the smoothest way of transitioning, but
can result in jittering or pixelization at the loop point. The
second wah of transitioning the file is that it waits for the file
to completely finish playback and come to a stop before
starting it again. This will cause a smal pause at the end of
athe file, but will eliminate jittering or pixelization at the loop
point.
You may select the transition type by changing the driver
parameter Loop Type. Setting it to 0 (zero) will produce the
first type of looping, setting it to 1 will produce the second.
