* GstAudioConvertInputChannelsReorder:
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_GST: reorder input channels
|
||||
* according to the default ordering in GStreamer: FRONT_LEFT, FRONT_RIGHT,
|
||||
* FRONT_CENTER, LFE1 and then the other channels. If there is only one
|
||||
* input channel available, it will be positioned to MONO.
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_SMPTE: reorder input channels
|
||||
* according to the SMPTE standard: FRONT_LEFT, FRONT_RIGHT, FRONT_CENTER,
|
||||
* LFE1 and then the other channels (the ordering is slightly different from
|
||||
* the default GStreamer order). This audio channels ordering is the only
|
||||
* one that is officially standardized and used by default in many audio
|
||||
* softwares (see: https://www.sis.se/api/document/preview/919377/). If
|
||||
* there is only one input channel available, it will be positioned to MONO.
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_CINE: reorder input channels as it
|
||||
* is commonly used in the cinema industry: FRONT_LEFT, FRONT_RIGHT,
|
||||
* FRONT_CENTER, the other channels and then LFE1. This configuration is not
|
||||
* standardized but usually appears in the literature related to the cinema
|
||||
* industry and as an alternate ordering in different audio softwares. On
|
||||
* some web sites, this configuration and the
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_AC3 ordering are switched. If
|
||||
* there is only one input channel available, it will be positioned to
|
||||
* MONO. If the number of available input channels is > 2, the last channel
|
||||
* will always be positioned to LFE1.
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_AC3: reorder input channels in the
|
||||
* same order as the default order of the AC3 format: FRONT_LEFT,
|
||||
* FRONT_CENTER, FRONT_RIGHT, the other channels (same order as in the
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_CINE policy) and then LFE1.
|
||||
* This configuration is also commonly used in the cinema industry and in
|
||||
* professional audio softwares (like ProTools under the name "FILM"
|
||||
* ordering). The only difference with the
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_CINE configuration is the
|
||||
* order of the first 3 channels. If there is only one input channel
|
||||
* available, it will be positioned to MONO. If the number of available
|
||||
* input channels is > 2, the last channel will always be positioned to
|
||||
* LFE1. If the number of available input channels is 2 or 3, the first two
|
||||
* channels will be positioned to FRONT_LEFT and FRONT_RIGHT.
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_AAC: reorder input channels in the
|
||||
* same order as the default order of the AAC format: FRONT_CENTER,
|
||||
* FRONT_LEFT, FRONT_RIGHT, the other channels (same order as in the
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_CINE configuration) and then
|
||||
* LFE1. The only difference with the
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_CINE configuration is the
|
||||
* order of the first 3 channels. If there is only one input channel
|
||||
* available, it will be positioned to MONO. If the number of available
|
||||
* input channels is > 2, the last channel will always be positioned to
|
||||
* LFE1. If the number of available input channels is 2 or 3, the first two
|
||||
* channels will be positioned to FRONT_LEFT and FRONT_RIGHT.
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_MONO: reorder all input channels
|
||||
* to MONO. All input channels are mixed together at the same level to a
|
||||
* virtual single mono channel. For `n` input channels, the virtual output
|
||||
* sample value is computed as:
|
||||
* `output_sample[MONO] = (1/n) x ∑ input_sample_for_channel(i)` with
|
||||
* `0 <= i < n`. A concrete usage for this configuration is, for example,
|
||||
* when importing audio from an array of multiple mono microphones and you
|
||||
* want to use them as a unique mono channel.
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_ALTERNATE: reorder all input
|
||||
* channels to FRONT_LEFT and FRONT_RIGHT channels alternately (or MONO if
|
||||
* there is only one input channel available). All left input channels are
|
||||
* mixed together, at the same level, to a single FRONT_LEFT virtual
|
||||
* channel and all right input channels are mixed together to a single
|
||||
* FRONT_RIGHT virtual channel. For `2n` input channels the FRONT_LEFT and
|
||||
* FRONT_RIGHT virtual output samples are computed as:
|
||||
* `output_sample[FRONT_LEFT] = (1/n) x ∑ input_sample_for_channel(2i)` and
|
||||
* `output_sample[FRONT_RIGHT] = (1/n) x ∑ input_sample_for_channel(2i+1)`
|
||||
* with `0 <= i < n` (in case of an odd number of input channels the
|
||||
* principle is the same but with an extra input left channel). A concrete
|
||||
* usage for this configuration is, for example, when importing audio from
|
||||
* an array of multiple stereo microphones and you want to use them as a
|
||||
* simple pair of stereo channels.
|
||||
*
|
||||
* Input audio channels reordering configurations.
|
||||
*
|
||||
* It defines different ways of reordering input audio channels when they are
|
||||
* not positioned by GStreamer. As a general matter, channels are always ordered
|
||||
* in the @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_GST order and the
|
||||
* `channel-mask` field in the audio caps allows specifying which channels are
|
||||
* active.
|
||||
*
|
||||
* Depending on the selected mode (see:
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_MODE_UNPOSITIONED), input channels
|
||||
* can be automatically positioned when the `channel-mask` is not specified or
|
||||
* equals 0. In this case, all input channels will be positioned according to
|
||||
* the selected reordering configuration and the index of each input channel.
|
||||
* This can be useful when importing audio from an array of independent
|
||||
* microphones for example.
|
||||
*
|
||||
* The reordering configuration can also be forced (see:
|
||||
* @GST_AUDIO_CONVERT_INPUT_CHANNELS_REORDER_MODE_FORCE) to reposition all
|
||||
* input channels according to each channel index. In this case the
|
||||
* `channel-mask` will be totally ignored and input channels will be reordered
|
||||
* just like if they were unpositioned. This can be useful when importing
|
||||
* multi-channels audio with errors in the channels positioning.
|
||||
*
