b6c43328ee avformat/matroskaenc: Avoid indirection via st->codecpar 
Use the already available AVCodecParameters pointer instead.
Shortens lines.

9ffac78eba avformat/matroskaenc: Fix and simplify check for invalid crop values 
The check "left >= INT_MAX - right" is supposed to check for
whether left + right does not overflow/wraparound, but given that
left and top are uint32_t INT_MAX - right can already wraparound
for big values of right (and ordinary 32-bit ints):
If right == UINT32_MAX, INT_MAX - right is INT_MAX + 1;
for left in 0..par->width both checks will be passed.

Fix this and simplify the check by using 64-bit types,
where the addition is guaranteed not to overflow.

avformat/rtsp: initialize reply1 
It seems reply1 is initialized by ff_rtsp_send_cmd() in most cases but there
are code paths like "continue" which look like they could skip it but even if not
writing this so a complex loop after several layers of calls initialized a local
variable through a pointer is just bad design.
This patch simply initialized the variable.
