[Libav-user] From buffer encoding

Hello everyone,

I have multiple questions that I couldn't find answers for. I am hoping 
that I'll get any answers here.
So, I am working on Qualcomm Snapdragon 820 android platform, I have 
6(!!) cameras attached on it, I have camera library
that supplies me with 30 raw 1280*720 yuv422 (UYVY) frames per sec in 
vector/buffer format. I need them to convert into h.264/5 video for real 
time(!!!) streaming.
     Does ffmpeg supports HW acceleration for This device? I couldn't 
completely find answer for that here: 
     And if doesn't support HW acceleration, is it possible to achieve 
real-time encoding without it.
     Is it possible to encode separate frames not from file? I am asking 
this because I got hard time with nonexistent appropriate documentation 
doing this in MediaCodec.

I would much appreciate if got any answers before i step deeper in 
ffmpeg API-s also any help or guidance too.

Best Regards.
