Issue description

When requesting http://ipcam/image.yuv420 for the first time, majestic starts to print failure messages. At the second time it segfaults:

Not enough mmz RAM for media data. Consider increasing blkCnt param in case if it's possible on the board

[TheChatty]

With blkCnt: 18I get valg alloc mmz buffer failed!.

With blkCnt: 17I see Free MMZ mem before allocation: 31868KB Free MMZ mem after allocation: 8372KB Free MMZ mem finally: 520KB but still get Cannot get chn 0 frame for vpssGrp=0, ERR_VENC_NOBUF: The buffer fails to be allocated due to ....

[widgetii]

There is no such amount of memory for 17 or 18 blocks

[TheChatty]

The important thing: with blkCnt: 10 I still can't take yuv420 image.
