From 82aa98fd9279dfe3e36679b7529f7b962939150e Mon Sep 17 00:00:00 2001 From: Dmitri Belimov Date: Tue, 28 Apr 2009 06:41:08 -0300 Subject: V4L/DVB (11733): increase MPEG encoder timout If video has a lot of changes in frame, MPEG encoder need more time for coding process. Add new bigger timeout for encoder. This is patch from our customer. I checked this.

Add start/stop TS function. 2. Move setup DMA of TS to DMA function. 3. Write support cupture via MMAP 4. Rework startup and finish process, remove simple FSM.
