* lavf/matroskadec: fix is_keyframe for early BlocksChris Cunningham2017-08-231-3/+7
| | | | | | | | | | | | | | | | | | Blocks are marked as key frames whenever the "reference" field is zero. This breaks for non-keyframe Blocks with a reference timestamp of zero. The likelihood of reference timestamp being zero is increased by a longstanding bug in muxing that encodes reference timestamp as the absolute time of the referenced frame (rather than relative to the current Block timestamp, as described in MKV spec). Now using INT64_MIN to denote "no reference".
