AMediaCodecBufferInfo on Nexus 6P has weird offset
(too old to reply)

Hi guys,

Not sure if this the appropriate place to post this, but we're trying to do
hardware VP8 encoding on the Nexus 6P with Android 8.1.0 (Latest updates,
compiled API level 24). When I dequeue an output buffer from the encoder,
the "offset" parameter in the info struct is a weird value (E.g.: 89534),
so if I apply the offset to the buffer pointer it points to nowhere and I
get a blank frame. If I ignore it (offset 0), however, the VP8 frame is
perfect!

The offset value is always this weird value around 89500 on the 6P, on
other devices, it seems to be a correct value. Is this a known issue? Is
there a way to investigate this?

Thank you!

Hello Eric,

Sounds like a bug. You can check here to see if was already reported:
https://source.android.com/setup/contribute/report-bugs
If not then you can report it.

Was this a regression from 23 to 24?
What other devices and versions were tested?
Is it consistent or intermittent?

Thanks,
Phil Burk
