New version of ffmpeg

Is it possible to compile ffmpeg ver 4.x for openwrt ?

Thank you jeff, good news are that Ive compiled ffmpeg 4.1 with Openwrt for MIPS/MT7620 and its working well. Bad news are that Im still having the same problem. I even reported a bug to ffmpeg. They asked me to try with current head git but I dont know how to do it,maybe you know ?

Here is my bug report:

For those feeling adventurous...
