wholesale fashion jewelry sets india Is the Oman GTL instantaneous fuel consumption?

wholesale gold rhinestone jewelry There are three ways to input audio input, follow the audio collection, audio input output capture and default device collection of video source.

. Follow the video source method

follow the video source signal (such as file, flow signal, collection card) embedded in the audio signal, add these signal sources to add these signal sources After that, the audio signal will be automatically identified and captured as an input audio signal source.

1. Audio and video files: When we choose a "source" method or "VLC video source" when we add a "source" to a certain scene, the audio signal will be captured and displayed by the system. "Mixed".

2. Stream signal: If we add stream signals such as RTMP, RTSP, when these flow signals are added, if the audio signal is embedded in the stream, the audio will be automatically captured by OBS and Hina will be automatically captured and Hina will be available. It is in the "mixer".

3. Collect card capture: This is a special case in collecting card capture. After installing the latest acquisition card driver, when adding a letter to the "Source" window, there will be a "device" option, as shown in the figure below:

For the collection card, we also recommend using this kind of use this type. Adding audio and video sources to ways can avoid the phenomenon of unsplevity of acoustic and painting. According to the test, if you use the "video capture device" "audio input capture" to add the collection card, it is easy to have no synchronization of sound and painting.

. Audio input output capture

audio input output capture refers to the audio signal that OBS can input and output device, and use these input or output audio signals as an OBS input signal. These devices generally include built -in speakers and microphones, external speakers and microphones, external sound cards, external video acquisition cards (embedded audio), and so on.

In external video collection cards for the synchronization of audio and video, generally add a timestamp to the collection card. For such a card, please be sure to use the device time stamp "to check, otherwise it will appear. The phenomenon of audio and video is not synchronized.

The audio output capture is actually equal to the output signal as an OBS input source. This will be used in some special occasions, such as using audio virtual output.

. The default device is collected

The settings of OBS-> audio menu, you can set the audio default device settings.

The signal source of the default device of the audio is the same as the audio input and output equipment at the second point. The biggest difference is 2 points:

1. n
The number of non -limited quantities is added to the method of audio input and output equipment, but the audio source is added by default collection.

2. The location of the audio display is different

In the use of the audio added by the default device collection method. The source of the letter has nothing to do with the scene. When switching the scene The audio source added with "following video source" and "audio input output capture" is bundled with a specific scene. After the scene is switched, the audio source will be cut off. Therefore, when there are multiple audio signals, we need to plan the method of adding audio in advance to avoid accidents.

I due to the limited number of audio sources due to the default device collection method, if more roads need to be supported at work, you can copy several audio sources in multiple scenarios
