mxc_vpu_test on IMX6 Android

satellite12 — Mon, 06 Jan 2014 08:08:11 GMT

Hi All,

In IMX6 Android BSP, there is a test tool "mxc_vpu_test" under //Android//device/fsl-proprietary/test/bin/

I use the tool to decode video, like mpeg4 or h.264, but get "vpu_DecOpen failed" error as below.

Ex:

root@android: # ./mxc_vpu_test -D "-i /mnt/sdcard/Movies/akiyo.mp4"

[INFO] VPU test program built on Nov 12 2009 11:17:18

[INFO] VPU firmware version: 2.1.9

[INFO] VPU library version: 36350.5.4

[INFO] Format: STD_MPEG4

[INFO] MPEG4 class: MPEG4

[INFO] Input file "/mnt/sdcard/Movies/akiyo.mp4" opened.

[ERR] vpu_DecOpen failed

Does anyone know how to use the tool?

Thanks.

Hello David,

Can you please tell me which version of Android did you install?, was it on SD or eMMC?

Hi David,

I got the same problem of mxc_vpu_test and I found the answer.

You have the build mxc_vpu_test from the source folder.

In this way you will got a "mxc-vpu-test" which is workable.

And the "mxc_vpu_test" comes from ./device/fsl-proprietary/* never works.
