| How to run renderscript in VP9 decode |
| |
| 1. Compile RenderScript Kernel(We use zero copy this version, |
| if ndk rs module don't support this, |
| it can't pass compile) |
| Because RenderScript need g++, but VP9 use gcc. |
| So we need to compile rs alone as a so library. Then VP9 project load/use it. |
| RS code is in vp9/common/kernel/rs/, there is a compile.sh in that folder, |
| We can use sh to compile rs kernel.(need NDK-r9b or higher, we need to config ndk in path). |
| If compile success, it will gen: |
| vp9_rs_packing.so(vp9/common/kernel/rs/) |
| librs.inter_rs.so(vp9/common/kernel/rs/obj/) |
| libstlport_shared.so(vp9/common/kernel/rs/obj/) |
| |
| 2. Compile VP9 project |
| Just Compile it normally. |
| |
| 3. Run vpxdec with RenderScript(We use zero copy this version, |
| if system RS module don't support this, |
| it won't work) |
| [1]: push vp9_rs_packing.so to /data/local/tmp/(or /vendor/lib, /system/lib, |
| need adb remount) |
| [2]: push librs.inter_rs.so to /data/local/tmp/(or /vendor/lib, /system/lib, |
| need adb remount) |
| [3]: push libstlport_shared.so to /data/local/tmp/(or /vendor/lib, /system/lib, |
| need adb remount) |
| [4]: push vpxdec to /data/local/tmp |
| [5]: adb shell (as root) |
| [6]: cd /data/local/tmp (on device) |
| [7]: export RSENABLE=1 (on device, if not, it won't use RS) |
| [8]: export QCTENABLE=1 (on device, enable qct kernel) |
| [9]: export OPENABLE=1 (on device, enable optimized kernel, dependence on system and driver) |
| [10]:export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/data/local/tmp (on device, |
| if we push .so file to /data/local/tmp, we need set this) |
| [11]:run vpxdec normally(on device) |
