* Long mp3 metadata displays as corrupted file after transferYin Liu2013-12-201-1/+1
| | | | | | | Cut the metadata to 1 Byte and return in function getObjectPropertyList in order to show it properly on a PC. Change-Id: Iefacf9fa86c20ece2572e6d95d35877a94066fe7

* MTP: Don't attempt to read more than 16K at a time from the MTP driverMike Lockwood2011-12-011-2/+4
| | | | | | | | This could happen sometimes if other operations increased the size of the data packet buffer to > 16K Change-Id: I4d316c7e2e558d3dd861d39accae6514fd9a62f5 Signed-off-by: Mike Lockwood <lockwood@google.com>
* MTP: Use a single packet for the data phaseMike Lockwood2011-07-171-37/+9
| | | | | | | | instead of sending 12 byte header in a separate packet. PTP on the Mac is much happier with this approach. Change-Id: I7d1ca498f6346afd88876d24332187b466fc469c Signed-off-by: Mike Lockwood <lockwood@android.com>

* MTP: Make sure buffer is big enough before reading the data packetMike Lockwood2010-11-301-0/+1
| | | | | | | Fixes buffer overflow when transferring large playlists. Change-Id: I1b7feaf9e56d849e5b6609f0f68a6aa5a3ae1ea8 Signed-off-by: Mike Lockwood <lockwood@android.com>
* PTP: Improve performance and reliability of file importingMike Lockwood2010-11-191-13/+17
| | | | | | | | | | | | | | | | Now the file copy is done completely within the media process rather than pushing data to the client via ContProvider.openFile(). File system writes are now interleaved with USB reads, which allows us to copy the data faster and prevents the camera from timing out during transfer. File is automatically inserted in the media provider after a successful import and a Uri is returned to the client.

* MTP: Use media provider database to implement MTP device support.Mike Lockwood2010-07-081-4/+15
| | | | | | | | | | | | | Uses a new "MTP objects" table in the media provider to support basic enumeration of the external storage file system. Support for accessing audio, video and image metadata in the existing media provider tables will be added in a later commit. The C++ MtpDatabase class is now abstract, to support a proxy subclass that calls through JNI to the Java MtpDatabase class in the media provider.

* Checkpoint work on MTP and PTP investigation.Mike Lockwood2010-05-131-0/+296
This change includes work in progress on a C++ library for both host and device MTP and PTP support. Currently the makefile builds two test programs: mtptest - a command line test program that implements a small subset of device side MTP. Requires a kernel driver that has not been checked in yet. ptptest - a host tool to test USB host support for detecting and communicating with digital cameras over PTP. Runs on Linux host. Later this will be reformulated as a native library that will be used in the media process. Change-Id: I81aab279975b600b59d99013ab97f9adf0b58da7 Signed-off-by: Mike Lockwood <lockwood@android.com>
