<p>Thanks David for replay,</p>
<p><br>
</p>
<p>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?</p>

it supports 60FPS HEVC decoding, but no where it mentions
about its capability to encode in HEVC. </p>

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.

interested in knowing too. </div>

<div>Hello everyone,<br>
<br>
I have multiple questions that I couldn't find answers
for. I am hoping that I'll get any answers here.<br>
So, I am working on Qualcomm Snapdragon 820 android
platform, I have 6(!!) cameras
<span id="result_box" class="short_text" lang="en"><span
class="">attached on it, I have camera library<br>
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.<br>

Does ffmpeg supports HW acceleration for This
device? I couldn't completely find answer for that
