From 582d887211612c197fc8ea9435503f9b278ce76f Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 24 Mar 2015 14:30:57 -0300 Subject: [PATCH] [media] coda: fix fill bitstream errors in nonstreaming case When queueing a buffer into the bitstream fails, it has to be requeued in the videobuf2 queue before streaming starts, but while streaming it should be returned to userspace with an error.
