  • Revision bac9beff72 : Merge "Fix active_map speed 6."

    8 août 2014, par Alex Converse

    Merge "Fix active_map speed 6."

  • Android built in Camera encoder VS FFMPEG --- Speed

    3 novembre 2015, par user3903275

    How does recording a 1080P, H264 encoded video in android camera application is realtime fast but encoding a video in android using FFMPEG is slow at the same video size ?

    I know FFMPEG is a software level encoder and it wont support any hardware features.

    I know camera applications directly get buffer data from camera driver.

    But actually where the difference happens ??

    Why camera application is Realtime fast ???

    Does it use GPU and OpenGL features of the phone to encode the video so that its so realtime fast ??

    Because both Camera Application and FFMPEG runs on same mobile but still camera encodes H264 realtime ???

  • Revision 62c6411820 : Remove neon version of vp8 extend borders The code fails the unit test. Speed c

    24 juillet 2014, par Johann

    Changed Paths :
     Modify /test/scale_border_test.cc


     Delete /vpx_scale/arm/neon/vp8_vpxyv12_extendframeborders_neon.asm


     Modify /vpx_scale/arm/neon/yv12extend_arm.c


     Modify /vpx_scale/vpx_scale.mk


     Modify /vpx_scale/vpx_scale_rtcd.pl



    Remove neon version of vp8 extend borders

    The code fails the unit test. Speed comparisons to the C are invalid
    because the code frequently didn’t correctly extend the right and
    bottom portions of the frame.

    Reduce maximum frame size on ARM devices to avoid OOM
