Subject: Audio Video synchronization for data received from a HDMI receiver
chip
Hi Linux media folks,
We are considering putting an advanced HDMI receiver chip on our SoC,
to allow reception of HDMI audio and video. The chip receives HDMI data
from a host like a set-up box or DVD player. It provides a video data
interface
and SPDIF/I2S audio data interface.
We plan to support the HDMI video using the V4L2 framework and the HDMI
audio using ALSA framework.
Now, what seems to be intriguing us is how the audio-video synchronization
will be maintained? Will a separate bridging entity required to ensure the
same
or whether this can be left upon a user space application like mplayer or
gstreamer.
Also is there a existing interface between the V4L2 and ALSA frameworks and
the same
can be used in our design?
Regards,
Bhupesh
