Allow user to specify alternate RVIO for export (with RV_RVIO_APP environment variable), even on Windows.

Hotkey to toggle Presentation Mode (control/command-P).

The -noPrefs command line option now prevents changes to the preferences file as well as not reading it on startup.

Mix of missing and present media files on RV command line could cause RV to hang.

Error in ARRI logC shader fixed.

With sequences of a particular length (2000-2500) frames, the Timeline Magnifier could absorb a lot of CPU and slow down playback.

ARRI file IO: use better debayering.

HDMI 1.4a Frame Packed Support Full-res HD stereo from any HDMI 1.4a-compliant device. In this first pass, you must set up the Frame Packed display resolution outside of RV, but once it’s there RV should be able to use it. On the Mac, RV will switch the resolution to the Frame Packed during presentation mode, but on Linux and Windows, you’ll need to activate that resolution yourself. Details here.

Annotation erase brushes fixed.

Pixel inspector was reporting values for the wrong pixel in some cases of EXR files with interesting data windows.

Ensure that audio added with setSourceMedia() causes initialization of the audio renderer.

Fixed errors when "relocating" one type of stereo source (say "sxr") to another (say "mov").

Fixed matte rendering in presentation mode when using mirrored output/control rendering.

Presentation Mode lets you display a full screen view on one monitor while controlling the playback from another. This is the same interface used by rvsdi. See the "Video" tab in the preferences and View→Presentation Mode.

DVI and HDMI 1.4a Support support for stereo TVs via presentation mode. Some setup is required to enable certain modes via third party tools or editing config files. (We’re still working on this as of 3.12.7). Supported stereo modes include HDMI 1.4 Side-by-Side and Top-and-Bottom, scanline interleave, and DLP checker. HDMI 1.4a "Frame Packing" mode will be supported in a future release.

ARRI Alexa Raw file handeling. LogC conversion using the exposure index automatically.

RED Raw (r3d). First pass at RED file support.

ACES Files and Color Space First pass at ACES support including writing .aces files from RVIO.

Output Primaries RV can now output to spaces other than Rec709 (e.g. P3). Currently this can be accomplished only via offline session file creation.

Per-source command-line arg "-rso" (Right-eye Stereo Offset)

Startup policy is now to start on same screen as pointer unless user chooses a specific screen.

Linux version now uses google’s breakpad for crash logs. If rv crashes, please send us the resulting ".dmp" file for analysis.

Repeated press of "\" (clear in/out points) now remembers and restores previous in/out points.

Window/Fit ("w") now sizes the window to fit the media without changing current zoom (if the resulting window fits on the screen).

"Topmost" stack comp mode renders only the topmost image in stack.

"Strict Frame Ranges" option on stack only renders inputs whose frame ranges overlap the current frame (IE first/last frames are not held).

"First Visible" audio option on stack to hear only the audio of the topmost visible element in the stack.

ProcessInfo mode was sometimes inteferring with annotation events.

Don’t show "play" feedback on screen during sync if "show feedback" pref is off.

Prevent Qt layer from interpreting -geometry flag, so -geoemtry should behave on linux as on other platforms.
