hi group,
i'm working on implementation of vendor omx section in froyo, and make
it run together with stagefright.
i notice that in android_root/hardware/qcom/media folder there are qcom's
implementations.
also i checked out samsung's omx code (from git://
github.com/codeworkx/android_device_samsung_galaxys.git), in which there is
also no audio omx component section.
i wonder why they(samsung and qcom) do not implement the audio omx section,
however, they have video omx's implementation.
here is my guess:
1. they do not implement audio decoder, but only using the audio decoder
originally in Android
2. they implement their own audio codec as the same way of Android's audio
codec, then substitute them,
3. they have other implementations of decoding audio that we do not know
can anyone give me some ideas? and what is your strategy of audio decoder,
omx way or using android's internal audio decoder
ps:
also, i have review the code of ti in android_root/hardware/ti/omp3, they
do have audio decoders such as aac, mp3, wma etc,
from normal logical, we should implement video and audio omx component
together, so we can play movie in full omx way.
my question is: why qcom and samsung do not implement audio omx but only
video omx component? and what audio decoder do they use when playing movie?
