H.264 SD Decode Memory Leak

Atsushi_S_ — Mon, 31 Mar 2014 02:10:36 GMT

Hello, I have serious trouble with Inte IPP.

I am developing Viewing Soft Ware of H.264 Video Stream Encoder.

For it, I use Intel IPP 8.0 Update 1 and w_ipp-sample_p_7.1.1.013.

And I build it with command "build.pl audio-video-codecs ia32, vc2008, d, st".

Then I tried to decode H.264 SD(720x480) with UMC::H264VideoDecoder.

Decoded Image is no problem, but memory leak happen.

So I resarched soft ware with Inspector XE where memory leak happen.

And It indicated thaht memory leak happen umc_h264_segment_store.cpp and umc_h264_task_supplier.cpp

SoftWare execute enviroment is

OS: Windows 7 Professional SP 1 (32bit)

CPU: Intel(R) Core(TM) i7-3770 3.40GHz

RAM:4.00GB

How can I fix it?

Please advise for me.

Hi,

Could you reproduce the issue with "umc_video_dec_con" application?

Hi,

Please also check if the Intel media SDK can meet your requirement, which include the hardware accelerator as well?http://software.intel.com/en-us/vcsource/tools/media-sdk

Since IPP sample code is put into legacy, in the new feature, it may not have much update.

Thanks,
Chao

Hello, Sergey. Thank you for your reply.

I tested with "simple_player.exe" for 3hours and checked it with Performance Monitor.

I think memory leak happen.

I attached print screen image of Performance Monitor.

It's leak little, but our viewing software exectute long time and use many UMC::H264VideoDecoder same time.

So, viewing software will hung up for 2 day.

Please advise to me.

Thank you.

Hello, Chao. Thank you for your reply.

I alerady investgate Media Sdk, but this time, I must use Inte IPP.

Media Sdk is next step.

Thank you.

Hello. Sergey.

I tried to test with "umc_video_dec_con.exe" and check memory with Performance Monitor.

I attached print screen of result.

I think it also happen memory leak.

Please check it.

Thank you.

Hi,

We would like to reproduce this. Could you tell how to get the same results as you did?

What stream to feed to umc_dec_con? Any H.264 stream?

Hello, Sergey. Thank you for

Hello, Sergey. Thank you for your reply.

I make file of H.264 Video Encode stream of 4 hours.

That's file is H.264 Pure Video and include AU Delimitter.

Encoder's setting is

Resolution : 720x480

Bitrate: 2M

Profile: Main Profile

Frame Rate:30fps

Picture type: I-Frame, B-Frame, P-Frame

GOP Size: 15

GOP Structure:3

and I execute umc_video_dec_con.exe like "umc_video_dec_con.exe -i filename -t 3 -f yv12"

That's result is

Stream type: H264PV

Track 0:H264 YUV420 (8,8,8) TFF 720x480 (1:1) 29.97fps P77 L30 *

Output data: YV12 (8,8,8) TFF 720x480 (1:1)

Progress: 1000.00%; Frames: 502429; FPS: 1609.28

Statistic (502429 frames):

Overall: 530.68 sec; 946.76 fps

Decoding: 480.76 sec: 1045.08 fps

Conversion: 39.70 sec; 12654.67fps

Decoded: 260459193600 bytes

Avg. bitrate: 1996590 bps

That's all.

Please check it.

Thank you.
