multi transcode sample doesnt work with "-la" option

[victor_e_]

Hi

I have a PC with Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz

I am running the precompiled sample binaries in the following way and this is the output

[root@localhost mediasdk_samples_bin]# ./sample_multi_transcode_drm -i::h264 /home/victor/Documents/MediaSDK/content/vq_src.264 -o::h264 /home/victor/Documents/MediaSDK/content/mss_out_5M_u1.265 -hw -la
Multi Transcoding Sample Version 5.0.1604371.71

libva info: VA-API version 0.35.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so
libva info: Found init function __vaDriverInit_0_32

Return on error: error code -1, /home/lab_msdk/buildAgentDir/buildAgent_MediaSDK2/work/48803f40a4a4f926/mdp_msdk-samples/samples/sample_multi_transcode/src/pipeline_transcode.cpp      2158

what is the problem?

Hi Victor,

Look Ahead is supported only for AVC encoding.(details are in manual Pg 38 Section 4.9.1)-  You can use other rate control methods like CBR and VBR.

Thanks,

Surbhi hello

thanks for your reply

but as you can see from my command line

./sample_multi_transcode_drm -i::h264 /home/victor/Documents/MediaSDK/content/vq_src.264 -o::h264 /home/victor/Documents/MediaSDK/content/mss_out_5M_u1.265 -hw -la

i am encoding the output to h264 (AVC), so what is the problem?

Regards,

Victor

I missed the o/p codec and because of your output extension, thought you are doing HEVC transcoding.
Can you please tell us which OS and Media Server Studio Package you are using? We don't have this problem on our systems. 
Couple of things you can try is to-
-Recompile the binaries and try again with same cmd line.
-try without -la option and see if the transcode goes through. (seeing the error, I am assuming this option should definitely work)

Please let us know your findings.

Surbhi hello

i am using the following package: MediaServerStudioProfessionalEvaluation2015R3

my OS is: CentOS Linux release 7.0.1406 (Core)

i am using the precompiled binaries that came with the Media Server Studio Package

without the -la option the transcoding works

waiting for your reply

Hi Victor,

Can you please check the kernel version. 
Type "uname -r" on the terminal and please let us know what the kernel evrsion is. This seems like an installation problem, the quickest way to solve this problem would be to reintsall and check.

We are also releasing a new kernel patch soon, will keep you posted. 

Thanks,

hi Surbhi

the kernel version is:

3.10.0-123.13.2.el7.x86_64

do you mean to re install the media sdk?

Thanks,
Victor

Hi Victor,

This is the original kernel of the CentOS, seems like Media Server Studio Kernel RPM wasn't installed. 
Please check the CentOS7 installation procedure in getting started guide -  https://software.intel.com/sites/default/files/managed/12/a9/media_server_studio_getting_started_guide_linux.pdf

After the MSS kernel is installed you should see something similar to below kernel version- 
3.12.28-4.6.29404.MSSr1-default

hi Surbhi

great news, i will start re-installing the MSS

will let you know of the outcome

Thanks,
Victor
