2018-08-03lavc/svq3: Fix regression decoding some files.Nikolas Bowe
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. Tested on the files in #6094 and http://samples.mplayerhq.hu/V-codecs/SVQ3/Vertical400kbit.sorenson3.mov Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2016-06-21svq3: stop using H264PictureAnton Khirnov
The SVQ3 decoder has been decoupled from the H.264 decoder, so it can now use its own data type.
2016-06-21h264: rename h264.[ch] to h264dec.[ch]Anton Khirnov
This is more consistent with the naming of other decoders.
