* MTP: Add extended operations to support in-place editing of filesMike Lockwood2011-04-221-0/+13
| | | | | | | | | | | | | | | | | | | | | | MTP does not support partial writes of files (the entire file must be transferred at once). This makes it impossible to implement a FUSE file system for MTP with acceptable performance. To fix this problem, this change adds extended MTP operations to allow partial writes to files: SendPartialObject - allows writing a subset of a file, or appending to the end of a file TruncateObject - allows changing the size of a file BeginEditObject - must be called before using SendPartialObject and TruncateObject EndEditObject - commits changes to a file after it has been edited with SendPartialObject or TruncateObject We also add GetPartialObject64, which is the same as GetPartialObject but has a 64 bit offset rather than 32.

* MTP: Partial implementation of the GetObjectPropList commandMike Lockwood2010-11-151-1/+5
| | | | | | | | | | In this initial implementation we only support fetching one property at a time. Support depth = 0 (single object) or depth = 1 (all objects in a directory) Reimplemented GetObjectPropValue on top of GetObjectPropList, since the former is a special case of the latter.

* Checkpoint work on MTP and PTP investigation.Mike Lockwood2010-05-131-0/+492
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>
