Hello Sir/Madam,

I am using Media SDK 2017 for Windows 8.0.24.271. I am using sample multitranscoder for transcoding the h264 stream. My hardware is Intel Core i7 -4770 CPU and Operating system is Windows 7.

My objective is work on raw Rgb4 frame. My input is input.h264(1920*1080). When I set -i::h264 input.h264 -o::raw output.raw -dc::rgb4 in transcoder sample. And exe throw m_pmfxDEC-> Init failed error. 

If i don't set below parameter then Transcoding Sample exe is running fine.

-dc::rgb4

Please advice me.

Thanking you,

Dhrumil Sheth

Hi Dhrumil,

Sorry for the late response, I was interrupted by some urgent project and had dealing with the long backlogs.

About your questions, I can reproduce it and I think the sample_multi_transcode might need other arguments to works. But -dc::rgb4 is to force the decoder output and you want to use raw.

If you just want to generate raw output with RGB4 format, you can use sample_decode with following command line:

sample_decode.exe h264 -i input.h264 -o out.raw -rgb4

Does this work for you?
