MXF Player on GPU

This is quite simple task to check how VLC Player or Windows Media Player can play MXF files from HDD/SSD. Even for 2K, the playback is extremely slow on a powerful PC and is far from being realtime or smooth. Moreover, conventional MXF workflow for frame preview, implies that MXF files have to be converted to MP4/MOV/AVI to watch video in any media player. Nevertheless, there is a way to play MXF files smoothly on Windows or Linux directly, without doing any preliminary conversion. Just try Fastvideo MXF Player which is working on NVIDIA GPU in real-time with 2K MXF files (4K MXF is coming soon).

MXF is an abbreviation for Material Exchange Format, which is a container format for professional digital video and audio media defined by a set of standards from the Society of Motion Picture and Television Engineers (SMPTE). MXF is a file format for the exchange of material between servers, tape streamers and digital archives.

MXF player from Fastvideo is included as sample application at Fastvideo Image & Video Processing SDK. The software can work with one or two GPUs to offer realtime MXF processing with smooth output. The first GPU is utilized for MXF decoding and it should be NVIDIA GPU, though the second GPU which is intended for video output, could be from Intel/NVIDIA/AMD. That two-GPU configuration is a good choice to offer both rendering and output in realtime. JPEG2000 decoding algorithm is computationally intensive, so we need help from the second GPU to output decoded data to the monitor. Soon we will add that application to download page of that site. That application can also work with just one NVIDIA GPU both for rendering and output. This is actually not a problem for 2K resolution, though for 4K it could be not enough.
