Hi Tomas, Thanks for that work. 1.2 was clean up of the Git repo, so nothing much has changed in terms of functionality. We have no plans for a fixed point version. The .c2 file format is a corner use-case (we focus mainly on the HF radio use case), but we have no plans to change it.
A road map of what is currently placed for the entire FreeDV project (which includes Codec 2) is here: https://freedv.org/2023/11/30/ardc-grant-project-plan/ Do you have any way of measuring how many people are using the Codec 2 option in FFmpeg? We have been looking into the use of the freedv-gui application (which uses libcodec2) in various repos and found no evidence of the packaged versions of freedv-gui actually being used. The number of package maintainers seems to to outnumber the end users. We are interested in auditing the use of freedv-gui and Codec 2 to best direct our efforts. For example there is no point supporting package maintainers if no one is using the packages - best to direct our limited resources elsewhere. I find it interesting that package maintenance is such a popular hobby - we get more correspondence/requests for help on this topic than say the DSP side of Codec 2 (where I like to play).
