Important License Note
----------------------
The license for the Blackmagic Design SDK essentially prohibits distribution
of any binaries containing their code. So for now, only source distribution,
or distribution of binaries not linked against the SDK, is legally permitted.

Quick Setup Guide (see wiki at http://github.com/asquared/openreplay):
----------------------------------------------------------------------
initial setup:
* Using a 64-bit kernel is recommended to enable large buffer use.
* You will probably want a multi-tabbed terminal emulator.
* If you're using it with PAL, you will have to do some hacking at the moment.
* get libjpeg or libjpeg-turbo, SDL, and SDL_image
(install development packages if necessary)
* If using Blackmagic capture cards for video I/O (not V4L compatible):
get Blackmagic SDK
set SDK_PATH in core/Makefile
maybe edit uyvy_ingest.cpp to use 720x486 frame size (if it doesn't work)
* If using other devices:
modify core/playoutd.cpp to use "StdoutOutput" class
(instead of "DecklinkOutput")
* from here: run 'make -C core'
* put binaries somewhere on your PATH
running 'export PATH=`pwd`/core:$PATH' is one way
setup before every production:
* Create capture buffer:
dd if=/dev/zero bs=1 count=1 seek=<xxx>G of=<your_buffer>
(replace <xxx> with desired size and <your_buffer> with a filename)
* Start a Video4Linux capture into the buffer:
v4l2_ingest /dev/videoX <your_buffer>
* Start a Decklink capture:
use Blackmagic Control Panel to set up input
decklink_capture <card_no> | uyvy_ingest <your_buffer>
* Start playout process:
if using a Decklink capture card:
playoutd <your_buffer> ....
if using non-Decklink output:
playoutd <your_buffer> .... | something_that_outputs_the_video
Note you can specify more than one buffer here if doing multicamera replay.
* Start GUI:
sdl_gui <your_buffer> ....
Specify buffer files here in same order as passed to playoutd.
operation:
* Capture a replay:
When something interesting happens, hit keypad '+' key. Output should show the first frame.
Hit 'F12' to roll it. F9 pauses. F10/F11 = frame advance/reverse.
updating:
git pull
make -C core
(copy binaries if necessary)
* See wiki for many additional features.
