From f4706d6e6d2d174af156b56d08cfca35121ac7cc Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 23 Jan 2015 13:51:27 -0300 Subject: [PATCH] [media] coda: issue seq_end_work during stop_streaming This patch queues seq_end_work and flushes the queue during stop_streaming and clears the ctx->initialized flag. This allows to start streaming again after stopping streaming without releasing the context.
