[FFmpeg-devel] [PATCH 10/14] avformat/matroskadec: move the elements semantic in a separate file
Steve Lhomme
robUx4 at ycbcr.xyz
Sun Mar 22 10:59:29 EET 2020
From: Steve Lhomme <robux4 at ycbcr.xyz>
So the file can be generated from the Matroska Schema.
The EbmlSyntax structures are not shared between files.
matroska_segments and matroska_cluster_enter also have their size predefined.
No functional changes.
