HEVC decoder exception

Hello,

 

I am unable to decode this HEVC stream from a Panasonic camera, other camera's work.

It generates an exception for every frame.


Best regards,

Robert

Hi,

 

We tried reproducing your issue and we observed that there's no issue with Decode sample in MediaSDK. It seems like the input file which you have attached is corrupted. To confirm this we have analyzed your input file using ffprobe (ffprobe tool from ffmpeg gathers information from multimedia streams and prints it in human- and machine-readable fashion) command :

 

ffprobe panasonic.265

 

We have attached the screenshot below. If you are not a ffmpeg user, you can install it from this link (https://ffmpeg.org/download.html).

Using :

               sample_decode.exe h265 -i panasonic.265 -o out1.yuv -sw

 

I see the h265_exception for every frame, is there a way to find out what is wrong?

I see it only for Panasonic CCTV camera streams, Axis, Bosch, Dahua work fine.

I think it has something to do with the SPS scaling_list, since thats the only difference i can see with the other camera's.

 

Exception thrown at 0x00007FF8FE0A4F99 in sample_decode.exe: Microsoft C++ exception: UMC_HEVC_DECODER::h265_exception at memory location 0x000000F3EB8FB080.

Hi,


We could reproduce your issue while running this sample with "-sw" option. We don't observe it when we remove that option or replace "-hw" option. Sample decode works with hardware implementation as well. So, we have provided a command below for sample decode example. Please check with the below command and let us know if it works or not. Also, regarding the error with software implementation, we are checking on this internally. we will get back to you with an update.


sample_decode.exe h265 -i panasonic.265 -o output.yuv


Thanks and Regards

Rahul

Thank you very much Rahul,

I will have a look to ffprobe, and check our RTSP code where it went wrong.

Best regards, Robert
