MPEG4 decode error on imx-6q

saurabh_a — Thu, 07 Feb 2013 07:21:48 GMT

Hello i.MX Community,

I want to decode MPEG4 decode with rotation on imx-6q using mxc_vpu_test application provided by freescale.

I execute the following command:

./mxc_vpu_test.out -D "-i /root/BlackBerry.mp4 -f 0 -r 90"

Output

[INFO] VPU test program built on Feb 7 2013 10:34:13

[INFO] Product Info: i.MX6Q/D/S

[INFO] VPU firmware version: 2.1.5_r32515

[INFO] VPU library version: 5.4.6

[INFO] Format: STD_MPEG4

[INFO] MPEG4 class: MPEG4

[INFO] Input file "/root/BlackBerry.mp4" opened.

[INFO] bitstreamMode 1, chromaInterleave 1, mapType 0, tiled2LinearEnable 0

[ERR] vpu_DecGetInitialInfo failed, ret:-1, errorcode:1

[ERR] decoder parse failed

I play the video using mplay and it plays fine.Could anyone tell me possible mistake I am doing by which call vpu_DecGetInitialInfo() is failing.

Regards,

Saurabh

mxc_vpu_test.out only support the ES stream playback, in your case , your playback file is mpeg4 format, the unit test code can't support it, so it will fail

Hello Mao,

Thanks for the reply.So that means that mxc_vpu_test.out is not a full fledged encoding decoding application?

But I have seen the test cases provided with the mxc_vpu_test test application for decoding of .mp4 files.If the test cases are provided in that bunch then test application should support it right?

Hi,

mxc_vpu_test has requirement to the decode file, it should be raw data, if any file can be decoded by it, the file should be raw data file.
