Greg,
when the simpleplayer plays clips containing both
video and audio, the audio may disappear randomly, and once the audio disapears,
it keeps silent ever since then. it happens even the complexity of the media is
very low and the decoding of audio and video only takes about 50% cpu. Can you
help me to find out what may cause this problem? Thanks.
one thing I want to point out is, the OS uses linux
default OSS audio driver. originally the simpleplayer plays audio with
wrong frequency. then I find the line in
audio/device/platform/unix/audlinux_oss.cpp does not return correct value, and
it does not support ODELAY correctly:
theErr = ::ioctl(m_nDevID,
SNDCTL_DSP_GETODELAY, &bytes2);
so I just comment it out and the simpleplayer can
player audio correctly, but the problem above happens.
The profile of the device:
OS: linux 2.2
CPU: ARM920T 206MHz
RAM: 32M
the build option of simpleplayer:
branch:
hxclient_1_3_0_neptunex_restricted
