Dear expert,

We have multi codec demo on openVX application. When I am testing the decoding feature on this demo, I encountered issue on decoding resolution. Pls take a look on how to change the decoding resolution on multi codec demo. Thanks .

1. Default demo, support 1920*1280, it works well.

2. When change to other resolution, like 720p or 1280*660 . Will encounter below issues.

Hello,

The default resolution for multiple channels appears to be 720p. You should be able to modify the resolution by changing the values under the downscale if-statement shown below:

Could you try modifying this and letting me know your results...

How are you modifying the resolution here?

Sarabesh,

That's not expected answer. My question is decoding 720P or other resolution.

1. The video source is 720P or other resolution. Default case is 1080P, that works well.

2. If the video is 720p for decoding, so don't need to downscale. Can you pls confirm this again? (Default setting didn't enable the flag)

3. My modification is just change the input resolution. From gst decoding setting, I didn't find the setting for input size.

Could you pls quickly try the 720p video on your side and let me know how to change the resolution on multi codec demo ? Thanks.

Regards,

Fredy Zhang
