What is FFmpeg in VoIP, and Why it is the Best Codec?
There are a lot of video and audio codecs available for VoIP. One of the most popular is the MP3 codec, but is it clear enough? The lack of a clear definition is what confuses the VoIP community. You may find some apparent differences between the MP3 codec and the one for VoIP, but is there a certain one that needs to be used to get the best results?
The main reason why there is confusion about the differences between the two is that both the FFMpeg and the Ogg formats are used way. That is why it can be hard to know which one you should use. Since the name and the video codec have been changed, it would be more convenient to use the version that comes with the package that you are using. As such, there is no one to blame for the confusion if the incompatibility continues.
Both the format and the codec have the same functions. The main difference between the two is the video compression algorithm. They are not identical. When we talk about MP3 and Ogg, we are talking about different formats that give us a different level of compression. You can see a difference between them when you compare the video quality.
When comparing the codec, we are comparing the video compression algorithm that is used. The actual code for the two differs by only a couple of percent. This is not much, but for some applications that need high-quality video, the difference can make the difference between getting low-quality audio and a higher quality one. The higher the quality, the smaller the file size and, therefore, the download speed of the VoIP call.
A codec that is too simple has a massive disadvantage because the better the quality higher the file size of the VoIP call. Hence, for a file size friendly VoIP codec, choose a good one.
In this case, two of the top three choices are the Ogg and the FFMpeg. The real difference between the two is the video compression algorithm. The reason why the MP3 codecs are considered more user friendly is the fact that they can produce a much better quality video.
When you compare the two formats, you will discover that they have almost the same video compression algorithm. It is only the level of compression that makes them different. Just like the bit rate that we discussed before, the real difference lies in the type of compression.
Each format uses a different method to compress the video, and this is the exact reason why the two have different audio compression methods. For example, when a user creates an audio file for the VoIP, the format will allow him to choose from two sizes to output the audio record. By default, it will select that has the highest bit rate.
That means the user needs to change the video codec to the one that has the lowest bit rate. While doing so, he can still output the audio as the final audio. So, with the two formats, the final audio file will always the highest bit rate.
However, that does not mean that the other format is not as good. Still, it is more secure against content being compromised because of the difference in the video compression algorithm. So, that makes sense in terms of security.
As for the video compression algorithm, the level of compression that it provides depends on the user settings and the model that is chosen for the VoIP call. The video compression algorithms usually selected by the person who wants to create a standard one.
So, the way to choose the best codec for VoIP calls one that is designed for this purpose. So, take care and choose a good one.
