In order to determine whether the current Cluster needs to be closed because of the limits on clustersize and clustertime, mkv_write_packet() would first get the size of the current Cluster by applying avio_tell() on the dynamic buffer holding the current Cluster. It did this without checking whether there is a dynamic buffer for writing Clusters open right now. In this case (which happens when writing the first packet) avio_tell() returned AVERROR(EINVAL); yet it is not good to rely on avio_tell() (or actually, avio_seek()) to handle the situation gracefully. Fixing this is easy: Only check whether a Cluster needs to be closed if a Cluster is in fact open. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
