From: Philipp Zabel Date: Tue, 18 Jun 2019 16:45:22 +0000 (-0400) Subject: media: coda: increment sequence offset for the last returned frame X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=493a15ad47a30c06563b7af8bb0882302b2c7398;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git media: coda: increment sequence offset for the last returned frame [ Upstream commit b3b7d96817cdb8b6fc353867705275dce8f41ccc ] If no more frames are decoded in bitstream end mode, and a previously decoded frame has been returned, the firmware still increments the frame number. To avoid a sequence number mismatch after decoder restart, increment the sequence_offset correction parameter.
