Hi all,
I have an application that is writing 2 D1 h264 videos on the SD card and I see
some slowdown on the thread that is saving the videos on sd card, when it is
mounted with the "sync" option.
I mean with a bitrate lesser than 1 MByte (2 D1 h264 videos), using a class 10
SD card mounted with the SYNC option, I can write on sd card at a frame rate of
max 20 fps on both the videos, while the capture tasks are running at 25 fps.
This means that I'm loosing 5 captured frames every sec on both the videos!
So my question is: is there a way to improve the driver write performance on
the SD card?
BTW the used file system is FAT32 and the hardware has a DM368 cpu with Linux
kernel 2.6.18 from Udworks
For us the "sync" option is a requirement, because the system should be power
cut safe.
Does anyone encountered the same problems?
Thanks in advance
Daniele
