Problems with Symbols, High Severity (2)

	Change	Effect
1	Parameter add_ftyp of type int has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
2	Parameter add_iods of type int has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

Problems with Symbols, Medium Severity (27)

	Change	Effect
1	Parameter oFormat of type char const* has been added to the calling stack.	This parameter will not be initialized by old clients.

	Change	Effect
1	Type of return value has been changed from bool (1 byte) to void.	Applications will not obtain a return value and execution may change.

	Change	Effect
1	Type of return value has been changed from bool (1 byte) to void.	Applications will not obtain a return value and execution may change.

	Change	Effect
1	Parameter retvalue of type float* has been added to the calling stack.	This parameter will not be initialized by old clients.
2	Type of return value has been changed from float to bool.	The return value became passed in different register. Applications will read the wrong memory block instead of the return value. Also, distribution of parameters on the available registers and stack may be changed.

	Change	Effect
1	Parameter retval of type u_int64_t* has been added to the calling stack.	This parameter will not be initialized by old clients.
2	Type of return value has been changed from u_int64_t (8 bytes) to bool (1 byte).	Applications will obtain a different return value and execution may change.

	Change	Effect
1	Type of 3rd parameter ppName has been changed from char const to char (became non-const).	This function may change parameter ppName, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.

	Change	Effect
1	Parameter index of type uint32_t has been added to the calling stack.	This parameter will not be initialized by old clients.

	Change	Effect
1	Parameter owner of type char const* has been added to the calling stack.	This parameter will not be initialized by old clients.

	Change	Effect
1	The pointer level of return value has been decreased from 1 to 0.	Applications may try to access unallocated memory by the dereferencing of new return value and therefore cause a crash.
2	Parameter retvalue of type char const** has been added to the calling stack.	This parameter will not be initialized by old clients.
3	Type of return value has been changed from char const* (4 bytes) to bool (1 byte).	Applications will obtain a different return value and execution may change.

	Change	Effect
1	Parameter ret_value of type float* has been added to the calling stack.	This parameter will not be initialized by old clients.
2	Type of return value has been changed from float to bool.	The return value became passed in different register. Applications will read the wrong memory block instead of the return value. Also, distribution of parameters on the available registers and stack may be changed.

	Change	Effect
1	Parameter retvalue of type u_int64_t* has been added to the calling stack.	This parameter will not be initialized by old clients.
2	Type of return value has been changed from u_int64_t (8 bytes) to bool (1 byte).	Applications will obtain a different return value and execution may change.

	Change	Effect
1	The pointer level of return value has been decreased from 1 to 0.	Applications may try to access unallocated memory by the dereferencing of new return value and therefore cause a crash.
2	Parameter retvalue of type char const** has been added to the calling stack.	This parameter will not be initialized by old clients.
3	Type of return value has been changed from char const* (4 bytes) to bool (1 byte).	Applications will obtain a different return value and execution may change.

	Change	Effect
1	Type of return value has been changed from float (4 bytes) to double (8 bytes).	Applications will obtain a different return value and execution may change.

	Change	Effect
1	Parameter trackId of type MP4TrackId has been added to the calling stack.	This parameter will not be initialized by old clients.

	Change	Effect
1	Type of return value has been changed from bool (1 byte) to void.	Applications will not obtain a return value and execution may change.

	Change	Effect
1	Parameter owner of type char const* has been added to the calling stack.	This parameter will not be initialized by old clients.

Problems with Data Types, Low Severity (2)

	Change	Effect
1	Field kms_uri became const.	The value of this field is expected to be const in new library version, but can be modified by old applications.
2	Type of field kms_uri has been changed from char* to char const*.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
