Hello, In a previous thread (3apr2012 - MTS player) I delineated some problems with the copy of files from a new HD sony camcorder to my gentoo system. This explains the nature of the problem: <snip> Files with CPI file extension are stored on the hard disk or memory card of AVHCD camcorders. File contains information (metadata) about captured video such as aspect ratio, frame rate and other information. CPI files are usually found in the AVCHD/BDMV/CLIPINF directory of the HD digital video recording media.
The "AVCHD" is a brand new high definition (HD) digital video camera recorder format recording 1080i and 720p signals onto certain media by using highly efficient codec technologies. The "AVCHD" is jointly established by Panasonic Corporation and Sony Corporation. <end/snip> Here are some things I have learned along the way that other might find useful: 1. "Reverse Engineering the Microsoft exFAT File System" is an excellent expose on learning about exFAT, which my new sony HDR-PJ760V camcorder uses. Facinating read for those interested in SD (SDHC and SDXC). 2. The trouble I was having, appeared to occur periodically, so initially I thought it was due to some "protection scheme" encoded by sony into their newer camcorders. What I found by trial and error is that auto-usb-mount (I just clicked on the Dolphin file manager each time the usb cable was inserted and click the usb-connect icon on the camcorder) is very sensitive and drops easily. Sure you can sometime just reinitialize the connection form the gentoo-kde tools, or sometime you need to reinitialize from the camcorder usb-connect gui. Some times you have to power cycle the camcorder and start with a fresh session to continue the copy process. So the usb-connections from my gentoo system to this sony camcorder is FRAGILE, for unknown reasons. 3. So, I removed the extra SD card I had installed and made sure that the "auto lens cover" was toggled to close and I was able to copy the files over with plain old "cp" across the auto-usb-mount provided via dolphin. The auto link then was stable enough to use this command: cp 0007[0-9].MTS /usr/local/TR/ To copy the files over. Use of a wildcard to copy files with one command, failed regardless of what I did. So, I lost the originating file information, not thinking about date/time stamps: (sony camcorder internal flash) -rw-r--r-- 1 james james 122M Mar 31 15:25 00053.MTS -rw-r--r-- 1 james james 173M Mar 31 15:27 00054.MTS -rw-r--r-- 1 james james 68M Mar 31 15:28 00055.MTS -rw-r--r-- 1 james james 22M Mar 31 15:29 00056.MTS cp yeilded this: (gentoo drive) -rw------- 1 root root 122M Apr 9 10:20 00053.MTS -rw------- 1 root root 173M Apr 9 10:32 00054.MTS -rw------- 1 root root 68M Apr 9 10:33 00055.MTS -rw------- 1 root root 22M Apr 9 10:34 00056.MTS So, not being the swiftest tack in the box on the use of rsync, could somebody suggest some detailed rsync syntax to correct the date/time stamp on the file in the gentoo host dir without other harm. Note the cp proceedure is very slow, suggesting that using "rate limiting" on the file transfer is probably a good idea? cp does not have a rate limited option, so should I try scp or rsync (syntax examples are most appreciated). I also saw a script that used "sleep 10" but that would only work between file names.... thoughts, comments and suggestions are most welcome. James
