## Description

Functions to create and handle encoding profiles.

Encoding profiles describe the media types and settings one wishes to use for an encoding process. The top-level profiles are commonly GstEncodingContainerProfile(s) (which contains a user-readable name and description along with which container format to use). These, in turn, reference one or more GstEncodingProfile(s) which indicate which encoding format should be used on each individual streams.

GstEncodingProfile(s) can be provided to the 'encodebin' element, which will take care of selecting and setting up the required elements to produce an output stream conforming to the specifications of the profile.

Unlike other systems, the encoding profiles do not specify which GstElement to use for the various encoding and muxing steps, but instead relies on specifying the format one wishes to use.

Encoding profiles can be created at runtime by the application or loaded from (and saved to) file using the GstEncodingTarget API.

#### Parameters

name | The name of the target. |
category | The name of the category to which this `target` belongs. For example: GST_ENCODING_CATEGORY_DEVICE. | [transfer none]
description | A description of GstEncodingTarget in the current locale. | [transfer none]
profiles | A GList of GstEncodingProfile. | [transfer none][element-type GstPbutils.EncodingProfile]

#### Returns

The newly created GstEncodingTarget or `NULL` if there was an error.

    typedef struct _GstEncodingProfile GstEncodingProfile;

The opaque base class object for all encoding profiles. This contains generic information like name, description, format and preset.

### GstEncodingContainerProfile

    typedef struct _GstEncodingContainerProfile GstEncodingContainerProfile;

Encoding profiles for containers. Keeps track of a list of GstEncodingProfile

### GstEncodingAudioProfile

    typedef struct _GstEncodingAudioProfile GstEncodingAudioProfile;

Variant of GstEncodingProfile for audio streams.

### GstEncodingVideoProfile

    typedef struct _GstEncodingVideoProfile GstEncodingVideoProfile;

### GST_ENCODING_CATEGORY_DEVICE

    #define GST_ENCODING_CATEGORY_DEVICE            "device"

GstEncodingTarget category for device-specific targets. The name of the target will usually be the constructor and model of the device, and that target will contain GstEncodingProfiles suitable for that device.

### GST_ENCODING_CATEGORY_ONLINE_SERVICE

    #define GST_ENCODING_CATEGORY_ONLINE_SERVICE    "online-service"

GstEncodingTarget category for online-services. The name of the target will usually be the name of the online service and that target will contain GstEncodingProfiles suitable for that online service.

### GST_ENCODING_CATEGORY_STORAGE_EDITING

    #define GST_ENCODING_CATEGORY_STORAGE_EDITING   "storage-editing"

GstEncodingTarget category for storage, archiving and editing targets. Those targets can be lossless and/or provide very fast random access content. The name of the target will usually be the container type or editing target, and that target will contain GstEncodingProfiles suitable for editing or storage.

### GST_ENCODING_CATEGORY_CAPTURE

    #define GST_ENCODING_CATEGORY_CAPTURE           "capture"

GstEncodingTarget category for recording and capture. Targets within this category are optimized for low latency encoding.

### GstEncodingTarget

    typedef struct _GstEncodingTarget GstEncodingTarget;

Collection of GstEncodingProfile for a specific target or use-case.

When being stored/loaded, targets come from a specific category, like GST_ENCODING_CATEGORY_DEVICE.

## Property Details
