Andreas Rheinhardt	b468ddc75d	avformat/matroskaenc: Don't waste bytes to Write Tag length fields This is possible by using a dynamic buffer to write them; said dynamic buffer is (re)used and reset as appropriate.

Andreas Rheinhardt	0148e85c3c	avformat/matroskaenc: Don't waste bytes on SimpleTags length fields Also check the (user-provided) tags for being overlong; the earlier code had an implicit unchecked size_t->int conversion.

Andreas Rheinhardt	99a4d16658	avformat/matroskaenc: Add option to shift data to write cues at front This is similar to the faststart option of the mov muxer, yet in contrast to it it works together with reserve_index_space (the equivalent to reserved_moov_size): If the reserved space does not suffice, the data is shifted; if not, the Cues are written at the front without shifting the data. Several tests that cover (not only) this have been added. Implements #7017. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2022-01-13 21:00:26 +01:00
