Where video.ogv is the file you want to open. There is a bitstream analyzer, with a GUI based on wxWidgets available. y4m files, and other tools can convert them to various other formats. Or you can pipe the raw video stream directly to the player of your choice: examples/dump_video video.ogv -o decoded_video.y4m If you want to use a different player, you can decode the video back to. Use encoder_example.exe -h for the in-built help.įor information on the controls available while playing, run
-o video.ogv is the name of the encoded video file to output. video.y4m is the input video you want to encode. -v ? specifies the amount of compression (currently from 0 to 511, where 0 is lossless, 511 is very lossy). examples/encoder_example -v 30 video.y4m -o video.ogv 
Subset 4 (1000 images, large testing set). Subset 3 (1000 images, large training set). Subset 2 (50 images, small testing set). Subset 1 (50 images, small training set). Xiph also maintains a set of still-image collections in. There are subsets of 1-second-long videos for faster encoding: These videos are relatively large and will take a long time to encode. Checking out a copy on Windows and then trying to use it on Linux will not work, as executable permissions and line-endings will not be set properly.
