Faq

• Did you come up with the name? No.
• How can I customize this? The primary inference config is in ~/.mce/pie.conf

Known Issues

• tests need to be written
• the decoder spews warning messages... not sure why
• videos don't always play at the correct rate. the --live option may help with some sources
• nvinfer doesn't respect batch-engine-file set at runtime for loading a file, leading to long start times.
