Thanks David for replay,

Maybe my question should be better defined, I know that my platforms Adreno 530 
GPU supports certain hardware accelerated encoding for both h.264 and h.265, 
but I failed to find any API for access it, so I was wondering is it integrated 
and supported in ffmpeg?

I think your question could be better answered at Qualcomm's developer's forum. 
And if the answer is yes the Adreno 530 GPU does support HW encoding for HEVC, 
the next stop is here to ask the ffmpeg developers whether that is integrated 
into ffmpeg.

Please let me know if you find out the answer, as I'm interested in knowing too.

thanks!

Subject: [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.
1:
    Does ffmpeg supports HW acceleration for This device? I couldn't completely 
find answer for that here: https://trac.ffmpeg.org/wiki/HWAccelIntro.
HWAccelIntro - FFmpeg<https://trac.ffmpeg.org/wiki/HWAccelIntro>
trac.ffmpeg.org
FFmpeg provides a subsystem for hardware acceleration. Hardware acceleration 
allows to use specific devices (usually graphical card or other specific 
devices) to ...



1.1:
    And if doesn't support HW acceleration, is it possible to achieve real-time 
encoding without it.
2:
    Is it possible to encode separate frames not from file? I am asking this 
because I got hard time with nonexistentappropriate documentation doing this in 
MediaCodec.

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

Best Regards.

Oljahim.


Hi Oljahim - This type of question might get a better response on the 
x264-devel list.  Ffmpeg afaik doesn't have an internal h264 encoder, only 
decoder.  It uses libx264 for encoding h264 video.
