To alleviate this, I've uploaded some +real-world video from the very first event where an early version of Futatabi +was tested. (There are some issues with the JPEG quality, but it should +largely be unproblematic.) You are free to use these for training or +demonstration purposes. Do note that they will not be displayed entirely +correctly in most video players (see :ref:`futatabiformat`), although +they will certainly be watchable. + +There are two files: + + * `Trøndisk 2018, finals only (MJPEG, 77 GB) `_: + The final match, in MJPEG format (roughly 52 minutes). This can be downloaded + and then fed directly to Nageru as if it were a real camera stream + (remember the --slow-down-input option). + * `Trøndisk 2018, entire tournament (H.264, 74 GB) `_: The entire tournament, + with no cuts (roughly 12 hours). However, due to space and bandwidth + constraints, it has been transcoded to H.264 (with some associated + quality loss), and needs to be transcoded to MJPEG before Nageru can use it. + +Both files are mixed-resolution, with some cameras at 1080p59.94 and some +at 720p59.94 (one even switches between matches, as the camera was replaced). +They contain four different camera angles (overview camera on crane, detail camera +in tripod, two fixed endzone overhead cameras) with differing quality depending +on the camera operators. In short, they should be realistic input material +to practice with. + +Please download these files only once, instead of streaming them directly over +HTTP each time you want to test. + + Transferring data to and from Nageru ------------------------------------ +.. _futatabiformat: + Video format specification ''''''''''''''''''''''''''
