I am trying to understand the role of context locks (CUvideoctxlock) for video decoders (CUvideodecoder). Unfortunately, I am unable to find any information on how to use them and when. An explaination would be much appreciated (I am familiar with the concept of locks/mutaxes etc in general).
When should one use a lock, and when should one skip it (from trying to decipher the public headers, it seems that using locks are optional)?
I my case I am planning to run several decoders in parallell (for decoding several videos simultaneously). Should I use one, several or zero context locks in this case?
Thanks in advance!
