i was experimenting with remuxing 5GB mov file by ffmpeg and found that 
resulting file was not playable by quicktime - it update picture during 
seeking on timeline only. after some bisecting of code i found that it 
happens since commit:


in my case resulting file has only ONE video track with constant frame 
size codec. as result after that commit mov file contains only one chunk.

after some attempts to find proper value i found that first working 
value was 1GB.

decreasing value makes quicktime opening video faster...
