Restore retry on spurious error

MediaCodec may fail spuriously, typically when stopping an encoding and
starting a new one immediately (for example on device rotation).

This was initially fixed by [1], but the fix was removed by [2], along
with the removal of the mechanism to retry capture at a lower resolution
on error.
