NoMachine 6.6.8 now available for download

Luxembourg, April 5th, 2019

NoMachine today announced an important software update offering multiple enhancements, the most significant of which is the inclusion of the AVC/H.264 software codec to the free-to-use packages for Windows, Linux, Mac and Raspberry: NoMachine and NoMachine Enterprise Client. From today, with the release of version 6.6.8, H.264 software encoding and decoding is available to everyone using NoMachine software.

NoMachine always prefers to use hardware encoding to produce the contents of the screen, using the GPU and the tools and methods it makes available. However, there are cases in which the GPU does not provide these tools or hardware encoding is not available. In these cases, NoMachine "falls back" to software encoding, which is slower and does not allow us to offer the same level of interactivity. Similarly on the client, where a hardware decoder is not available, software decoding is used.

In previous free versions, the software encoder and decoder used were based on the VP8 standard, unless the user had purchased the additional AVC Pack which includes the libraries, protected by an international patent by the MPEG LA consortium, and which therefore required a license fee.

From this version, NoMachine has decided to include these libraries covering the costs of the user license fees at its own expense, thus offering the best performance offered by the video encoding standard known as AVC/H.264. This, as already mentioned, where the GPU or HW system in use does not offer an H.264 hardware encoder or decoder, which, again as mentioned, is always the preferred method by NoMachine software.

This update also introduces other enhancements such as improvements to how NoMachine server handles the heaviest peaks of user log-in demand, and the possibility to define the rate control mode ('bitrate' or 'quality') in sessions where multi-media is being streamed. Additionally, the OpenSSL libraries provided by NoMachine have been updated to OpenSSL v. 1.0.2r.

FR02Q03776 Giving the possibility to stop sharing a printer as public
FR04Q03813 Updating the OpenSSL libraries provided by NoMachine to version 1.0.2r
FR04Q03812 Updating nxhtd to Apache v. 2.4.39
FR03Q03803 Improving access to NoMachine backend for multiple concurrent connections
