  How FPS reduction for H264 without transcode? [duplicate] - Александр А Newest 'ffmpeg' Questions - Stack Overflow
  There is a USB camera that sends H264 frames with a frequency of 30 fps in a resolution of 1920x1080, GOP size 30 or 60 (1 or 2 I frame per second depending on the camera and only P-frames), which requires throughput of about 6 mbit/s. It is necessary to reduce this to no more than 2 mbit/s. All this is done on a weak ARMv7, so the option of transcoding is extremely resource intensive, especially considering that I did not find how to do it as a GPU Mali (NanoPi Neo Core). Given that the basic functionality is performed on the framework ffmpeg, is it possible to reduce the frame (...)
