Intel® Media RAW Accelerator Help - input of JPEG output JPEG Modified

[Vladimir_P_Intel1]

hi ,

i am new to Intel® Media RAW Accelerator and i am trying to preform simple action on a jpeg file .

i am using sample_decode with the following command :

"C:\Users\XXX\Documents\Intel® Media SDK 2019 R1 - Media Samples 8.4.27.25\_build\Win32\Debug\sample_decode.exe" jpeg -jpeg_rotate 90 -d3d11 -i "C:\Users\XXX\Desktop\123.jpeg" -o "C:\Users\vpikovsk\Desktop\124.jpeg" 

i am simply trying to rotate and create a new file .

file NV12 is being created as an output and i have learned that this is a video format.

what i have to do in order to obtain jpeg as an output ?

thanks in advance !

Hi Vladimir,

sample_decode output the raw image uncompressed from input, if your input is a single image, it should be a frame format not video. you can try sample_encode to compress it back to jpeg.

You can also use sample_multi_transcode to set both input and output as JPEG with the "-angle" parameter of 90 degree. Refer the detail to this page:

Hi Vladimir,

I think this is related to jpeg profile, I got the same error as yours for one JPEG file, but I got succeed with following file:

https://commons.wikimedia.org/wiki/File:Intel-logo.jpg

The error you got is the bitstream header decoding failure, so this related to the JPEG profile. As our document, we support Baseline profile,

https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/mediasdkjpeg-man.md#CodecProfile

I check my file that doesn't work, it has profile description "sRGB IEC61966-2.1", I am not the expert on this but it looks like not a baseline profile.
