I'm working with iMX8MMini as streaming device and now need Widevine Level 3 support for DRM content. We found that Widevine need us to provide OEMCrypto version for the SoC. We're currently using Yocto version imx-5.4.70-2.3.0 in our product. In the CECDM/OEMCrypto git provided I can download up to version 17.1.
I want to know is there specific OEMCrypto version do my platform support? or I can just use the most updated one?
