* 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. 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>

| | | | | | | | | | | | | | | | | | Currently it incorrectly compares bits with bytes. Also, move the check right before where it's relevant, so that the correct number of remaining bits is used. CC: libav-stable@libav.org
