From 8702b9dac7bc3785102153a3b95085db01df17f9 Mon Sep 17 00:00:00 2001 From: Harvey Yang Date: Wed, 8 Feb 2023 03:33:18 +0000 Subject: android: jpeg: Pass StreamBuffer to Encoder::encoder To prepare for support of the JEA encoder in a following commit, which will need to access the buffer_handle_t of the destination buffer, pass the StreamBuffer to the Encoder::encoder() function. As the StreamBuffer contains the source FrameBuffer and the destination Span, drop them from the function arguments and access them directly from the StreamBuffer.
