[Libav-user] From buffer encoding

[David Yuan]

Based on this a little dated announcement on Qualcomm, https://www.qualcomm.com/news/releases/2015/08/12/qualcomm-introduces-next-generation-gpu-architecture-and-image-signal, it supports 60FPS HEVC decoding, but no where it mentions about its capability to encode in HEVC.

Qualcomm Introduces Next-Generation GPU Architecture and ...<https://www.qualcomm.com/news/releases/2015/08/12/qualcomm-introduces-next-generation-gpu-architecture-and-image-signal>
www.qualcomm.com
Qualcomm Incorporated (NASDAQ: QCOM) today announced that its subsidiary, Qualcomm Technologies, Inc. (QTI), has introduced its next-generation visual processing ...

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!
David

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 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.

Oljahim.
