-/**
- * Following API allows user to probe device capabilities (supported codecs,
- * pixel formats, sample formats, resolutions, channel counts, etc).
- * It is build on top op AVOption API.
- * Queried capabilities make it possible to set up converters of video or audio
- * parameters that fit to the device.
- *
- * List of capabilities that can be queried:
- *  - Capabilities valid for both audio and video devices:
- *    - codec:          supported audio/video codecs.
- *                      type: AV_OPT_TYPE_INT (AVCodecID value)
- *  - Capabilities valid for audio devices:
- *    - sample_format:  supported sample formats.
- *                      type: AV_OPT_TYPE_INT (AVSampleFormat value)
- *    - sample_rate:    supported sample rates.
- *                      type: AV_OPT_TYPE_INT
- *    - channels:       supported number of channels.
- *                      type: AV_OPT_TYPE_INT
- *    - channel_layout: supported channel layouts.
- *                      type: AV_OPT_TYPE_INT64
- *  - Capabilities valid for video devices:
- *    - pixel_format:   supported pixel formats.
- *                      type: AV_OPT_TYPE_INT (AVPixelFormat value)
- *    - window_size:    supported window sizes (describes size of the window size presented to the user).
- *                      type: AV_OPT_TYPE_IMAGE_SIZE
- *    - frame_size:     supported frame sizes (describes size of provided video frames).
- *                      type: AV_OPT_TYPE_IMAGE_SIZE
- *    - fps:            supported fps values
- *                      type: AV_OPT_TYPE_RATIONAL
- *
- * Value of the capability may be set by user using av_opt_set() function
- * and AVDeviceCapabilitiesQuery object. Following queries will
- * limit results to the values matching already set capabilities.
- * For example, setting a codec may impact number of formats or fps values
- * returned during next query. Setting invalid value may limit results to zero.
- *
- * Example of the usage basing on opengl output device:
- *
- * @code
- *  AVFormatContext *oc = NULL;
- *  AVDeviceCapabilitiesQuery *caps = NULL;
- *  AVOptionRanges *ranges;
- *  int ret;
- *
- *  if ((ret = avformat_alloc_output_context2(&oc, NULL, "opengl", NULL)) < 0)
- *      goto fail;
- *  if (avdevice_capabilities_create(&caps, oc, NULL) < 0)
- *      goto fail;
- *
- *  //query codecs
- *  if (av_opt_query_ranges(&ranges, caps, "codec", AV_OPT_MULTI_COMPONENT_RANGE)) < 0)
- *      goto fail;
- *  //pick codec here and set it
- *  av_opt_set(caps, "codec", AV_CODEC_ID_RAWVIDEO, 0);
- *
- *  //query format
- *  if (av_opt_query_ranges(&ranges, caps, "pixel_format", AV_OPT_MULTI_COMPONENT_RANGE)) < 0)
- *      goto fail;
- *  //pick format here and set it
- *  av_opt_set(caps, "pixel_format", AV_PIX_FMT_YUV420P, 0);
- *
- *  //query and set more capabilities
- *
- * fail:
- *  //clean up code
- *  avdevice_capabilities_free(&query, oc);
- *  avformat_free_context(oc);
- * @endcode
