From the developer:
vooya is a player for raw (uncompressed and containerless) video data, most commonly used in scientific and broadcast/OTT environments, and has a variety of features which makes working with raw data easier for codec developers, signal processing experts, and film freaks.
vooya also supports image sequences in TIFF, DPX, Radiance and OpenEXR, as well as the infamous y4m (YUV4MPEG) format or AVI.
You may want to check out more Mac applications, such as MFilter, Aiseesoft WMV Converter for Mac or AkBrowser, which might be similar to vooya.
