jpeg decoder can't output 444P format for YUV444 jpeg file

[xhaihao]

Sample clip: https://github.com/Intel-Media-SDK/MediaSDK/files/2720196/smpte_444P.jpeg.zip.zip MSDK doesn't support 444P fourcc and the output is always NV12.

What output format we should use (in sample_decode pipeline)? AYUV? we have no suitable FOURCC in api now.

[chuanli1]

this case can decode successfully on local machine.

[xhaihao]

chuanli1 could you provide your command?

[chuanli1]

Is this output format the default？I use the default and output format '-ayuv' command line： ./sample_decode jpeg -i smpte_444P.jpeg -o output_ayuv.yuv -hw ./sample_decode jpeg -i smpte_444P.jpeg -o output_ayuv.yuv -hw -ayuv

[xhaihao]

It is using VPP to convert NV12 to AYUV.

Output format   AYUV (using vpp)

@chuanli1 Your result is converted by MSDK VPP. @xhaihao hopes sample_decode output AYUV directly because this JPEG is AYUV format. Could you please add this support in MSDK. Thanks.

[chuanli1]

Thanks @xhaihao and @wangyan-intel ,I try to enable this output format in our msdk.

Hi, output format ayuv is supported in sample_decode

[chuanli1]

Hi, it is using VPP to convert NV12 to AYUV, but sample app can't output 444P format for YUV444 jpeg file directly.

@SofyaBalandina Could you please confirm with @chuanli1's comments? If yes, could you please add it? Thanks.

@xhaihao This issue is similar with https://github.com/Intel-Media-SDK/MediaSDK/issues/1960 and @SofyaBalandina has replied in it. Could you please check it? If OK, could we close this issue? Thanks.

[xhaihao]

@SofyaBalandina Did you mean JPEG decoder in the SDK supports NV12, RGB32, and YUY2 only, right ? JPEG in the media driver may support other formats, see https://github.com/intel/media-driver/blob/master/docs/media_features.md#jpeg-decoding-format-support, e.g. 444P for 4:4:4 8-bit jpeg file and 400P for 4:0:0 8-bit jpeg file. Is it possible to support these formats in the SDK too ?

[wangyan-intel]

@onabiull Could you please check @xhaihao's comments? Is it possible to add support in sample_decode?

[onabiull]

@wangyan-intel, adding more formats to sample_decode should be possible. But biggest part is in MSDK https://github.com/Intel-Media-SDK/MediaSDK/issues/1960#issuecomment-724479705.
