A Push Towards Firmware-less Video Decoding By Linux Kernel Media Drivers

17. Květen 2019 - 12:40
Veteran Linux multimedia developer Paul Kocialkowski summed up the current situation this week of many hardware platforms having a general purpose micro-controller running a non-free firmware blob for coordinating the video decoding work. It makes it easier to program with this firmware-based approach but makes the driver less free and now with recent Linux infrastructure improvements could better support dealing with the video hardware itself...
