* avcodec/mediacodecdec: fix SEGV on modern nvidia decodersAman Gupta2018-08-03
| | | | | | | | | | | | | | | | | | | | This code came originally from gstreamer, where it was added in [1] as a work-around for the Tegra 3. (The alignment was changed in [2] as a response to [3], from 32-bit to 16-bit). gstreamer only used this workaround in the case where the decoder didn't return a slice-height property, but when the code was copied into avcodec the conditional got lost. This commit restores the guard and prefers the slice-height from the decoder when it is available. This fixes segfaults decoding 1920x1080 h264 and mpeg2 videos on the NVidia SHIELD after upgrading to Android Oreo.

* lavc/svq3: Fix regression decoding some files.Nikolas Bowe2018-08-03
| | | | | | | | | | | Fixes some SVQ3 encoded files which fail to decode correctly after 6d6faa2a2d. These files exhibit lots of artifacts and logs show "Media key encryption is not implemented". However they decode without artifacts before 6d6faa2a2d. The attatched patch allows these files to successfully decode, but also reject media key files.
