+ melted instance that hosts a local parser.
1.1. Construction of a Local Parser
To construct a local parser you must have:
- #include <miracle/miracle_local.h>
+ #include <melted/melted_local.h>
and code to initialise the parser is as follows:
- valerie_parser parser = miracle_parser_init_local( );
+ mvcp_parser parser = melted_parser_init_local( );
See Appendix A for compilation and linking details.
To construct a remote parser you must have:
- #include <valerie/valerie_remote.h>
+ #include <mvcp/mvcp_remote.h>
and code to initialise the parser is as follows:
- valerie_parser parser = valerie_parser_init_remote( "server", port );
+ mvcp_parser parser = mvcp_parser_init_remote( "server", port );
See Appendix A for compilation and linking details.
Regardless of use, it is the constructors responsibility to close the
parser before it goes out of scope. This is done via:
- valerie_parser_close( parser );
+ mvcp_parser_close( parser );
2. The High Level Parser Wrapper
--------------------------------

+ The recommended way to access the parser, is via the mvcp API. To use
this API, you must have:
- #include <valerie/valerie.h>
+ #include <mvcp/mvcp.h>
and code to construct the wrapper is:
- valerie dv = valerie_init( parser );
+ mvcp client = mvcp_init( parser );
Note that either remote or local parsers can be used here and there is no
difference in usage, though some error returns will not be applicable to
It is recommended that applications honour and deal with the error returns
of both as this allows applications to interchange parsers.
- Also note that valerie is not threadsafe, so you should not use the same
+ Also note that mvcp is not threadsafe, so you should not use the same
structure in multiple threads. The correct solution to this is to create a
- valerie per thread - you may safely use the same parser for each thread ie:
+ mvcp per thread - you may safely use the same parser for each thread ie:
- /* valerie for the application */
- valerie dv = valerie_init( parser );
- /* valerie for the status handling thread. */
- valerie dv_status = valerie_init( parser );
+ /* mvcp for the application */
+ mvcp client = mvcp_init( parser );
+ /* mvcp for the status handling thread. */
+ mvcp client_status = mvcp_init( parser );
For the purposes of simplification, the remainder of this section assumes
that a remote parser is in use.
Once constructed, the next thing to do is 'connect':
- valerie_error_code error = valerie_connect( dv );
+ mvcp_error_code error = mvcp_connect( client );
This function call initialises the parser (ie: if it's remote, it
establishes a connection to the server, or if it's local, it initialises
the state of the units and supporting objects).
- Note that if you have multiple valerie instances on the same parser you
+ Note that if you have multiple mvcp instances on the same parser you
should only connect one of the instances.

- All but a couple of the functions that make up the valerie API return a

+ All but a couple of the functions that make up the mvcp API return a
+ mvcp_error_code.
These are defined as follows:
- valerie_ok = 0,
- valerie_malloc_failed,
- valerie_unknown_error,
- valerie_no_response,
- valerie_invalid_command,
- valerie_server_timeout,
- valerie_missing_argument,
- valerie_server_unavailable,
- valerie_unit_creation_failed,
- valerie_unit_unavailable,
- valerie_invalid_file,
- valerie_invalid_position
-
- In most cases, it is sufficient to check on a return of valerie_ok.
+ mvcp_ok = 0,
+ mvcp_malloc_failed,
+ mvcp_unknown_error,
+ mvcp_no_response,
+ mvcp_invalid_command,
+ mvcp_server_timeout,
+ mvcp_missing_argument,
+ mvcp_server_unavailable,
+ mvcp_unit_creation_failed,
+ mvcp_unit_unavailable,
+ mvcp_invalid_file,
+ mvcp_invalid_position
+
+ In most cases, it is sufficient to check on a return of mvcp_ok.
To obtain a textual description of a particular error, you can use:
- char *valerie_error_description( valerie_error_code );
+ char *mvcp_error_description( mvcp_error_code );
2.3. Using the High Level Wrapper
---------------------------------
- The following code snippet assumes that dv is an initialised and connected

+ The following code snippet assumes that client is an initialised and connected

- valerie_error_code error = valerie_unit_play( dv, 0 );
- if ( error == valerie_ok )

+ if ( error == mvcp_ok )
fprintf( stderr, "Unit 0 is now playing\n" );
else
fprintf( stderr, "Play on unit 0 failed: %s\n",
- valerie_error_description( error ) );
+ mvcp_error_description( error ) );
- The complete interface to valerie is listed in Appendix B of this document.
+ The complete interface to mvcp is listed in Appendix B of this document.
2.4. Obtaining Directory Contents
--------------------------------
To obtain a list of files and subdirectories in a given directory relative
- to the ROOT property of the server, DVCP provides the CLS command.
+ to the ROOT property of the server, MVCP provides the CLS command.
A valid execution of CLS would be something like:
of a subdirectory and the 3rd and 4th line lists two files that happen to
exist in the directory.
- valerie provides a high level view on this which automatically parses the
- response from the server correctly via the valerie_dir structures and
+ mvcp provides a high level view on this which automatically parses the
+ response from the server correctly via the mvcp_dir structures and
related functions.
An example of use is as follows:
- valerie_dir dir = valerie_dir_init( dv, "/Stuff" );
- valerie_error_code error = valerie_dir_get_error_code( dir );
- if ( error == valerie_ok )
+ mvcp_dir dir = mvcp_dir_init( client, "/Stuff" );
+ mvcp_error_code error = mvcp_dir_get_error_code( dir );
+ if ( error == mvcp_ok )
{
- if ( valerie_dir_count( dir ) > 0 )
+ if ( mvcp_dir_count( dir ) > 0 )
{
- valerie_dir_entry_t entry;
+ mvcp_dir_entry_t entry;
int index = 0;
- for ( index = 0; index < valerie_dir_count( dir ); index ++ )
+ for ( index = 0; index < mvcp_dir_count( dir ); index ++ )
{
- valerie_dir_get( dir, index, &entry );
+ mvcp_dir_get( dir, index, &entry );
if ( entry.dir )
printf( "<%s>\n", entry.name );
else
else
{
fprintf( stderr, "Directory listing failed: %s\n",
- valerie_error_description( error ) );
+ mvcp_error_description( error ) );
}
- valerie_dir_close( dir );
+ mvcp_dir_close( dir );
Note that entry.name provides the name of the file or directory without the
directory prefix. As a convenience, entry.full provides the prefixed name,
so you could subsequently use:
- error = valerie_unit_load( dv, 0, entry.full );
+ error = mvcp_unit_load( client, 0, entry.full );
to load unit 0 with an entry.
2.5. Obtaining the Node List
----------------------------
- Currently not defined by miracle.
+ Currently not defined by melted.
2.6. Obtaining the Unit List
----------------------------
- To obtain a list of defined units, DVCP provides the ULS command.
+ To obtain a list of defined units, MVCP provides the ULS command.
A valid execution of ULS would be:
The fields of each record in the response dictate unit, node, mlt consumer and
online status respectively.
- valerie provides a high level view on this which automatically parses the
- response from the server correctly via the valerie_units structures and
+ mvcp provides a high level view on this which automatically parses the
+ response from the server correctly via the mvcp_units structures and
related functions.
An example of use is as follows:
- valerie_units units = valerie_units_init( dv );
- valerie_error_code error = valerie_units_get_error_code( units );
- if ( error == valerie_ok )
+ mvcp_units units = mvcp_units_init( client );
+ mvcp_error_code error = mvcp_units_get_error_code( units );
+ if ( error == mvcp_ok )
{
- if ( valerie_units_count( units ) > 0 )
+ if ( mvcp_units_count( units ) > 0 )
{
- valerie_unit_entry_t entry;
+ mvcp_unit_entry_t entry;
int index = 0;
- for ( index = 0; index < valerie_units_count( units ); index ++ )
+ for ( index = 0; index < mvcp_units_count( units ); index ++ )
{
- valerie_units_get( units, index, &entry );
+ mvcp_units_get( units, index, &entry );
printf( "U%d %02d %s %s\n",
entry.unit,
entry.node,
else
{
fprintf( stderr, "Unit listing failed: %s\n",
- valerie_error_description( error ) );
+ mvcp_error_description( error ) );
}
- valerie_units_close( units );
+ mvcp_units_close( units );
2.7. Unit Status Information
There are two methods for a client to obtain unit status information.
- The first is via the DVCP USTA command, which would normally be accessed
+ The first is via the MVCP USTA command, which would normally be accessed
via:
USTA U0
* Playlist generation
* Clip index
- Again, valerie provides a high level means for obtaining this via the
- valerie_unit_status function and valerie_status structures:
+ Again, mvcp provides a high level means for obtaining this via the
+ mvcp_unit_status function and mvcp_status structures:
- valerie_status_t status;
- valerie_error_code error = valerie_unit_status( dv, 0, &status );
- if ( error == valerie_ok )
+ mvcp_status_t status;
+ mvcp_error_code error = mvcp_unit_status( client, 0, &status );
+ if ( error == mvcp_ok )
{
switch( status.status )
{
else
{
fprintf( stderr, "Unit status failed: %s\n",
- valerie_error_description( error ) );
+ mvcp_error_description( error ) );
}
The second approach for obtaining a units status is via automatic
notification.
- This is done via the valerie_notifier API. To obtain the notifier from the
+ This is done via the mvcp_notifier API. To obtain the notifier from the
high level API, you can use:
- valerie_notifier notifier = valerie_get_notifier( dv );
+ mvcp_notifier notifier = mvcp_get_notifier( client );
To obtain the last status associated to a unit, you can use:
int unit = 1;
- valerie_status_t status;
- valerie_notifier_get( notifier, &status, unit );
+ mvcp_status_t status;
+ mvcp_notifier_get( notifier, &status, unit );
To wait for the next status from any unit, you can use:
- valerie_notifier_wait( notifier, &status );
+ mvcp_notifier_wait( notifier, &status );
If you wish to trigger the action associated to your applications wait
handling of a particular unit, you can use:
- valerie_notifier_get( notifier, &status, unit );
- valerie_notifier_put( notifier, &status );
+ mvcp_notifier_get( notifier, &status, unit );
+ mvcp_notifier_put( notifier, &status );
See Examples below for details on this.
* set in/out points allows you to modify clip in and out points
Backward compatability has been maintained by the addition of a clip-aware
- family of APIs which have the naming convention of valerie_unit_clip_*.
+ family of APIs which have the naming convention of mvcp_unit_clip_*.
These are listed in Appendix B.
The following shows an example of obtaining the clips queued on unit 0:
- valerie_list list = valerie_list_init( dv, 0 );
- valerie_list_entry_t entry;
+ mvcp_list list = mvcp_list_init( client, 0 );
+ mvcp_list_entry_t entry;
int index;
printf( "Generation = %d\n", list->generation );
- for ( index = 0; index < valerie_list_count( list ); index ++ )
+ for ( index = 0; index < mvcp_list_count( list ); index ++ )
{
- valerie_list_get( list, index, &entry );
+ mvcp_list_get( list, index, &entry );
printf( "%d %s %d %d %d %d\n",
entry.clip,
entry.full,
entry.max,
entry.size );
}
- valerie_list_close( list );
+ mvcp_list_close( list );
To load a clip on unit 0:
- valerie_unit_load( dv, 0, "/path/clip.dv" );
+ mvcp_unit_load( client, 0, "/path/clip.dv" );
To append a clip on unit 0:
- valerie_unit_append( dv, 0, "/path/clip.dv", -1, -1 );
+ mvcp_unit_append( client, 0, "/path/clip.dv", -1, -1 );
Note that the last two arguments specify the in and out points of the clip
with -1 denoting dfaults of the entirety of the file.
To insert a clip at position 0 on unit 0, we can use the following:
- valerie_unit_clip_insert( dv, 0, clip_absolute, 0, "/path/clip.dv", -1, -1 );
+ mvcp_unit_clip_insert( client, 0, clip_absolute, 0, "/path/clip.dv", -1, -1 );
- The 3rd and 4th arguments here are common to all the valerie_unit_clip functions.
+ The 3rd and 4th arguments here are common to all the mvcp_unit_clip functions.
They take the form of either [clip_absolute, n] to indicate an absolute clip
index, or [clip_relative, n] to indicate a clip index relative to the
currently playing clip.
So, to insert a clip immediately before the currently playing clip, we can
use:
- valerie_unit_clip_insert( dv, 0, clip_relative, -1, "/path/clip.dv", -1, -1 );
+ mvcp_unit_clip_insert( client, 0, clip_relative, -1, "/path/clip.dv", -1, -1 );
To move the current clip to the next position in the list:
- valerie_unit_clip_move( dv, 0, clip_relative, 0, clip_relative, 1 );
+ mvcp_unit_clip_move( client, 0, clip_relative, 0, clip_relative, 1 );
To remove a specific clip:
- valerie_unit_clip_remove( dv, 0, clip_absolute, index );
+ mvcp_unit_clip_remove( client, 0, clip_absolute, index );
To remove all but the currently playing clip:
- valerie_unit_clean( dv, 0 );
+ mvcp_unit_clean( client, 0 );
To goto the first frame in the first clip, you can use:
- valerie_unit_clip_goto( dv, 0, clip_absolute, 0, 0 );
+ mvcp_unit_clip_goto( client, 0, clip_absolute, 0, 0 );
To set the in and out points on the current clip:
- valerie_unit_clip_set_in( dv, 0, clip_relative, 0, 0 );
- valerie_unit_clip_set_out( dv, 0, clip_relative, 0, 1000 );
+ mvcp_unit_clip_set_in( client, 0, clip_relative, 0, 0 );
+ mvcp_unit_clip_set_out( client, 0, clip_relative, 0, 1000 );

+ The demo client provided with mvcp is used for retaining backward
compatability with the client side queuing API.
The methods are provided via a pair of high level methods:
- valerie_error_code error = valerie_execute( dv, 1024, "USTA U%d", unit );
- valerie_response response = valerie_get_last_response( dv );
+ mvcp_error_code error = mvcp_execute( client, 1024, "USTA U%d", unit );
+ mvcp_response response = mvcp_get_last_response( client );
int index = 0;
- for ( index = 0; index < valerie_response_count( response ); index ++ )
- printf( "%d: %s\n", index, valerie_response_get_line( response,index ) );
+ for ( index = 0; index < mvcp_response_count( response ); index ++ )
+ printf( "%d: %s\n", index, mvcp_response_get_line( response,index ) );

3. The Low Level Parser API
------------------------
All commands can be executed via the single variable argument function
- valerie_parser_executef and this function returns a valerie_response, ie:
+ mvcp_parser_executef and this function returns a mvcp_response, ie:
- valerie_response response = valerie_parser_executef( parser, "CLS \"%s\"", dir );
+ mvcp_response response = mvcp_parser_executef( parser, "CLS \"%s\"", dir );
Note that no carriage return/line feed is required (adding this is
erroneous).
It is the receiver of the response who is responsible for closing it.
- valerie_response_close( response );
+ mvcp_response_close( response );
-3.2. Interpreting valerie_response
+3.2. Interpreting mvcp_response
-----------------------------
The response received can be NULL, but it is safe to call:
- int error = valerie_response_get_error_code( response );
+ int error = mvcp_response_get_error_code( response );
which will return:
* -1 if response is NULL,
* -2 if there is no content to the response,
- * 0 if the responses first line does not correspond to a valid DVCP response
- * or the DVCP protocol error code returned on the first line of the response
+ * 0 if the responses first line does not correspond to a valid MVCP response
+ * or the MVCP protocol error code returned on the first line of the response
- A simple use of a valerie_response structure is as follows:
+ A simple use of a mvcp_response structure is as follows:

+ int error = mvcp_response_get_error_code( response );
if ( error >= 0 )
{

The latter is the recommended way for any applications which wish to extract
meaningful information from the status while avoiding the requirement to
The notifier can be obtained by:
- valerie_notifier notifier = valerie_parser_get_notifier( parser );
+ mvcp_notifier notifier = mvcp_parser_get_notifier( parser );
The use of the notifier with the low level parser is identical to that
dictated in Section 2 - to obtain the last status associated to a unit,
you can use:
int unit = 1;
- valerie_status_t status;
- valerie_notifier_get( notifier, &status, unit );
+ mvcp_status_t status;
+ mvcp_notifier_get( notifier, &status, unit );
To wait for the next status from any unit, you can use:
- valerie_notifier_wait( notifier, &status );
+ mvcp_notifier_wait( notifier, &status );
