libdc1394 : Migration from 1.x to 2.0

Foreword

Libdc1394 has grown in complexity with time and has been patched and repatched numerous time, making it difficult to maintain. It also starts to be difficult to use it which means it's time for a little cleanup! ;-) I have worked for almost a year on the 2.0 branch which solves many issues with 1.0, but also brings new problems to the light. It's also a beta version at this stage: you have been warned. Nevertheless, the API is more or less stable at this point and following a suggestion from a user I am proposing below a guide on how to migrate your application from the 1.0 branch to the new 2.0 branch. For now the guide is limited to a few guidelines followed by an equivalence table for every function of the library. Enjoy! And don't forget to report omissions, errors or propose enhancement to this guide. ;-)

Types and definitions

Here's a short itemized list of what is changed.

  • all definitions now start with the 'DC1394_' prefix to avoid conflicts. This means that a lot of definitions have changed. Sorry. I don't mention below the definitions for which it's the only change.
  • video modes definitions are different presented because the IIDC 'format' is now hidden (except for format7). That means that you don't have to supply a mode and format anymore; only the mode is necessary. See below for more details.
  • color codings names have changed to be more consistant with IIDC names (COLOR_FORMAT to COLOR_CODING).
  • color filter definitions are now DC1394_COLOR_FILTER_XXXX instead of COLOR_FILTER_FORMAT7_XXXX
  • error definitions are new in libdc 2.0. See the section about error reporting.
  • Several enum types have been added:
    • dc1394switch_t (DC1394_ON, DC1394_OFF). I don't like the 'switch' name but it's all I could think of.
    • dc1394trigger_polarity_t (DC1394_TRIGGER_ACTIVE_LOW, DC1394_TRIGGER_ACTIVE_HIGH) for the trigger polarity
    • dc1394feature_mode_t (DC1394_FEATURE_MODE_MANUAL, DC1394_FEATURE_MODE_AUTO, DC1394_FEATURE_MODE_ONE_PUSH_AUTO) for the operation mode of a feature.
    • dc1394video_mode_t
    • dc1394capture_policy_t
    • dc1394iidc_version_t
    • dc1394color_coding_t
    • dc1394color_filter_t
    • dc1394operation_mode_t
    • dc1394trigger_source_t
    • etc... etc...
    Functions prototypes have been modified to reflect this. It will allow stronger 'typing' and error detection at the compilation phase.
  • The capture API and camera detection API have changed significantly. A new frame type has been introduced.

Structures

This is one of the areas that needed a cleanup and as you will see it's much simpler now. The general guideline is that everything concerning a camera is now in a single struct called 'dc1394camera_t'. No more handles. And the dc1394capture_t is in there too (it will be removed from the API soon when access functions will be defined). For those who looked at the guts of libdc, we used to access some hidden struct in the raw1394handle, which was quite ugly IMHO. It's much cleaner now.

This big change will be apparent in the API later so I won't comment too much on it now. The next thing is that several structs have been introduced. These are dc1394colormodes_t, dc1394video_modes_t and dc1394framerates_t. It was necessary because the functions for these features are now sending back lists of items instead of ugly binary masks.

Error reporting

Almost all functions have been changed to return a new type of value: dc1394error_t. This is an enum type defined in dc1394/log.h.

Errors are logged and returned to the parent function using four macros:

DC1394_ERR(err, err_string...)
DC1394_ERR_RTN(err, err_string...)
DC1394_ERR_CLN_RTN(err, cleanup, err_string...)
DC1394_ERR_CLN(err, cleanup, err_string...)
DC1394_WRN(err, err_string...)

The last one does not return, it simply logs a warning message.

The macros behaves like this:

  • prints an error/warning message with a description of the error code, the filename in which it happened, the function name, the line number and a user supplied string.
  • executes the cleanup code supplied (only for *CLN* functions)
  • returns the error code to the parent function, halting the execution of the current function (only for *RTN functions).
  • DC1394_ERR only returns ("return;") without any value. This breaks the trace but allows the macro to be used within functions that do not return the "dc1394_error_t" or "int" type.
  • DC1394_WRN does not "return" and the calling function will continue after printing the error message.

The macros are typically called like this:

dc1394error_t err;
err=dc1394_reset_camera(&camera);
DC1394_ERR_RTN(err, "Ooops, my example program failed\n");

The error code is sent to the successive parent functions and you will thus have several errors printed one after each other, giving you a nice trace of what happened. The use of these macros is not limited to libdc internals: you can also include them in your programs (and you're even encouraged to do so). The macros are built to allow you to add values inside the user-supplied error message (i.e. the number of arguments is variable). Example:

DC1394_ERR(err, "Ooops, my example program failed for the %dth time today!\n",n++);

Note that you should not check errors by including a libdc1394 function inside the call to the error macro, otherwise the libdc function will be executed multiple time, leading to more errors (since it already failed),... in an endless loop. IOW, you should NOT write something like this if you want ot check that the reset worked well:

DC1394_ERR_RTN(dc1394_reset_camera(&camera), "Ooops, my example program failed\n");

This is obvious when you know that you are playing with macros but it's worth repeating anyway. Note also that the error function doesn't do anything if the error code is negative (which denotes a warning only). In that case you have to handle it.

Libdc1394 does not print anything to stdout or stderr anymore, or at least you can ask it to do so. A new error logging mechanism has been written, in which three types of error handlers can be assigned by the user (error, warning, debug)

The function changes (aka The Big Gun)

This is the real thing. Let's go through it.

Function name in v2 Function name in v1 Comments

General system and camera functions (camera.h)

dc1394_t*
dc1394_new
(void)
- Initialises a context in which the library can be used
void
dc1394_free
(dc1394_t *dc1394)
- Frees the context in which the library was used
void
dc1394_free_camera
(dc1394camera_t *camera)
- free a camera structure. You should not simply use free() to do that because handles must be removed as well as several other internal things.
dc1394error_t
dc1394_camera_enumerate
(dc1394_t *dc1394, dc1394camera_list_t **list)
- locates the cameras. This used to be performed by dc1394_get_camera_misc_info, dc1394_create_handle, dc1394_get_camera_nodes, dc1394_get_sw_version, dc1394_get_camera_info and dc1394_is_camera. As you can see it's much simpler now! The new function also loops on all the available ports and has a few extras that were move from coriander to libdc1394 (duplicate removal, among others). This function does not provide the camera structs themselves; it mearly tell you which GUIDs on the bus are IIDC cameras.
void
dc1394_camera_free_list
(dc1394camera_list_t *list)
- Frees a list of cameras provided by dc1394_camera_enumerate
dc1394camera_t*
dc1394_camera_new
(dc1394_t *dc1394, uint64_t guid)
- Initialise a camera structure for the camera whos GUID is specified.
dc1394camera_t*
dc1394_camera_new_unit
(dc1394_t *dc1394, uint64_t guid)
- Initialise a camera structure for the camera whos GUID and unit number are specified.
void
dc1394_camera_free
(dc1394camera_t* camera)
- Frees a camera structure.
dc1394error_t
dc1394_reset_bus
(dc1394camera_t *camera)
- Resets the IEEE1394 bus which camera is attached to. Calling this function is "rude" to other devices because it causes them to re-enumerate on the bus and may cause a temporary disruption in their current activities. Thus, use it sparingly. Its primary use is if a program shuts down uncleanly and needs to free leftover ISO channels or bandwidth. A bus reset will free those things as a side effect.
dc1394error_t
dc1394_read_cycle_timer
(dc1394camera_t * camera, uint32_t * cycle_timer, uint64_t * local_time)
- ?
- int
dc1394_get_camera_info
(raw1394handle_t handle, nodeid_t node, dc1394_camerainfo *info)
removed from tha API. This piece of code is integrated in dc1394_camera_new() and dc1394_camera_new_unit().
dc1394error_t
dc1394_camera_print_info
(dc1394camera_t *camera, FILE*fd)
void
dc1394_print_camera_info
(dc1394_camerainfo *info)
the output has been improved but the function is basically the same as in v1. You can also print to any file you want (including stdout)
dc1394error_t
dc1394_camera_set_broadcast
(dc1394camera_t *camera, dc1394bool_t pwr);
- New. Sets and resets the broadcast flag of a camera. If the broadcast flag is set, all devices on the bus will execute the command. Useful to sync ISO start commands or setting a bunch of cameras at the same time. Broadcast only works with identical devices (brand/model). If the devices are not identical your mileage may vary. Some cameras may not answer broadcast commands at all. Also, this only works with cameras on the SAME bus (IOW, the same port).
dc1394error_t
dc1394_camera_get_broadcast
(dc1394camera_t *camera, dc1394bool_t *pwr);
- Tells whether a camera is in broadcast mode or not.

- Read the data depth from the camera. This is interesting only for 16 bit modes, although I can imagine that it would be interesting that if is a camera out there that outputs less than 8 effective bits on an 8 bit. For example, if you read 10 there it means that only the 10 first bits out of the 16 sent by the camera are valid (the others are usually zero). If the value returned by this function is 0 (ZERO) you should not use it, obviously.

The format/fps/image/size/position/... must now be set before separately. As a result, this function is used both for fixed image formats and for Format_7. Note that the DMA device file is not an argument anymore: it is probed automatically. If you have exotic device filenames you will have to use a specific function (dc1394_set_dma_device_filename) before calling this setup function. Also, the camera capture struct is gone (it is now hidden in the dc1394camera_t struct). At last, ISO channels are allocated automatically so that the argument is gone too (you can still do manual allocation if necessary).

Manual ISO ressource management (iso.h)

dc1394error_t
dc1394_iso_set_persist
(dc1394camera_t * camera)
- Calling this function will cause isochronous channel and bandwidth allocations to persist beyond the lifetime of this dc1394camera_t instance. Normally (when this function is not called), any allocations would be automatically released upon freeing this camera or a premature shutdown of the application (if possible). For this function to be used, it must be called prior to any allocations or an error will be returned.
dc1394error_t
dc1394_iso_allocate_channel
(dc1394camera_t * camera, uint64_t channels_allowed, int * channel)
- Allocates an isochronous channel. This function may be called multiple times, each time allocating an additional channel. The channel is automatically re-allocated if there is a bus reset. The channel is automatically released when this dc1394camera_t is freed or if the application shuts down prematurely. If the channel needs to persist beyond the lifetime of this application, call dc1394_iso_set_persist() first. Note that this function does _not_ automatically program @camera to use the allocated channel for isochronous streaming. You must do that manually using dc1394_video_set_iso_channel().
dc1394error_t
dc1394_iso_release_channel
(dc1394camera_t * camera, int channel)
- Releases a previously allocated channel. It is acceptable to release channels that were allocated by a different process or host. If attempting to release a channel that is already released, the function will succeed.
dc1394error_t
dc1394_iso_allocate_bandwidth
(dc1394camera_t * camera, int bandwidth_units)
- Allocates isochronous bandwidth. This functions allocates bandwidth _in addition_ to any previous allocations. It may be called multiple times. The bandwidth is automatically re-allocated if there is a bus reset. The bandwidth is automatically released if this camera is freed or the application shuts down prematurely. If the bandwidth needs to persist beyond the lifetime of this application, call dc1394_iso_set_persist() first. *
dc1394error_t
dc1394_iso_release_bandwidth
(dc1394camera_t * camera, int bandwidth_units)
- Releases previously allocated isochronous bandwidth. Each dc1394camera_t keeps track of a running total of bandwidth that has been allocated. Released bandwidth is subtracted from this total for the sake of automatic re-allocation and automatic release on shutdown. It is also acceptable for a camera to release more bandwidth than it has allocated (to clean up for another process for example). In this case, the running total of bandwidth is not affected. It is acceptable to release more bandwidth than is allocated in total for the bus. In this case, all bandwidth is released and the function succeeds.
dc1394error_t
dc1394_iso_release_all
(dc1394camera_t * camera)
- Releases all channels and bandwidth that have been previously allocated for this dc1394camera_t. Note that this information can only be tracked per process, and there is no knowledge of allocations for this camera by previous processes. To release resources in such a case, the manual release functions dc1394_iso_release_channel() and dc1394_iso_release_bandwidth() must be used.
