This function will be useful later to reset the status (e.g. current level and the already parsed id). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> --- This function is not used yet, so compilation will likely result in a warning because of an unused function. This will be fixed with the next commit. Splitting this into two commits is a suggestion by Steve. libavformat/matroskadec.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+)
