Hi all, I'm having trouble stabilizing a video pipeline using MediaCodec and Camera.PreviewCallback. I understand that specifying YV12 in Camera.setPreviewFormat should yield a tri planar YUV420 image in the preview callback. On the Nexus 7, this is the behavior I have seen, however the Galaxy Nexus callback returns a YUV 420 image with interpolated chroma layers (bi planar).
Thus far, I have been able to identify this device quirk by the auxiliary issue of the TI Ducati H264 encoder being unable to consume tri planar YUV 420 as a color format (with the MediaCodec API capabilities API). Although I have not seen this quirk in any other Nexus device, I am concerned this position exposes us to future headache if the device behavior should change, or if another device we have not tested has the same quirk alongside different preview image format behavior. For reference, here is a stub that would establish the preview callback that's been troubling me: https://gist.github.com/f536efdf780d6fdb2e98 Is there something I'm missing here with respect to using setPreviewFormat? Has anyone run into issues with the Camera preview format? Do I file a bug for this?
