If anyone has any objections, please let me know. ------------------ From: Philipp Zabel commit 74dc385cb450089b28c28be2c8a0baca296b95f9 upstream. During the recent vb2_buffer restructuring, the calculation of the buffer payload reported to userspace was accidentally broken for the first encoded frame, counting only the length of the headers. This patch re-adds the length of the actual frame data.
