I have encoubter a same problem

the error is “JPEG parameter struct mismatch: library thinks size is 720, caller expects 728”. it is a known issue. please refer to JPEG parameter struct mismatch Error in deepstream-transfer-learning-app DS V6.2.

but my platform is jetson orin nano,my jetpack version is 5.1.1 and ds version is 6.2
tensorrt version is 8.5.2.2

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

As mentioned in the JPEG parameter struct mismatch Error in deepstream-transfer-learning-app DS V6.2 - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums, either JetPack 5.1 GA+DeepStream 6.2 or JetPack 5.1.2GA+DeepStream6.3 works.
