Hi Marton,
Hope the email here can explain: http://ffmpeg.org/pipermail/ffmpeg-devel/2022-December/304534.html
As I noticed, the native backend only supports a few models, which was an outcome after many layers' implementation in FFmpeg DNN module. Naturally, it would take many other works to support other models.
What's more, due to its' ordinary, unsatisfied performance, almost users choose other well-developed DNN framework for inference.
I believe that's the main reason to remove native from DNN module.
Thank you
Ting Fu
