[FFmpeg-devel] [PATCH 22/23] avformat/matroskaenc: Don't waste bytes on length fields
Andreas Rheinhardt

Wed Nov 6 04:49:21 EET 2019
Several EBML master elements for which a good upper bound of the final
length was available were nevertheless written as unknown-length
EBML-elements, so that their length field was eight bytes long. This has
been changed.
