OMX.qcom.video.decoder.avc.secure is not available (Qualcomm H.264 hardware decoding)
Which version of the software are you running?
Fairphone OS & Fairphone Open 21.11.1-re.0
In Android 6 and earlier, OMX.qcom.video.decoder.avc.secure was enabled and available. In Android 7, we dropped it (by not including required libraries and implementations). Also in Android 9 it is not available, and first attempts to re-enable it caused various new failures (CTS, potentially other issues as well). Same goes for Android 10.
On Android 10 Fairphone 2, Android's default H.264 software decoder (provided by Google) is used instead.
