ff_Build_SDK_INT always fail when JVM isn’t available and target
api level < 24. If there are more usecases of ff_Build_SDK_INT(),
we might make it more robust.
For current use case:
1. If JVM is available, ff_Build_SDK_INT() should success, nothing changed.
2. If JVM is unavailable, sdk_int > 0 && sdk_int <= 23 should always be false,
since android_get_device_api_level() only available after API >= 24. Then
amlogic_mpeg2_api23_workaround doesn’t work. Even if we can make
ff_Build_SDK_INT()
works when API < 24, get codec name doesn’t work, then
amlogic_mpeg2_api23_workaround
doesn’t work neither. I don’t think it’s a serious issue. Old usecase with JNI
works, and this special workaround might not necessary now.
The patch fixed a hypothetical case when the codec is
OMX.amlogic.mpeg2.decoder.awesome
and the device api level >= 28 (get codec name works after API >= 28),
amlogic_mpeg2_api23_workaround is enabled (which shouldn’t).
