Before learning how to fix this problem, let us understand what an H.264 decoder plugin is? An H.264 decoder is a plugin that not only encodes but also decodes the content. Because of this, it is also known as a codec. Codec is a device that not only encodes the data but also decodes it after the encoding. Similarly to this concept, the codec in videos also encodes the data, or we can say it packages and un-packages the content for the streaming and recording of the video. In the process of encoding, the H.264 compresses the size of the video file so it can conveniently transfer over a long distance and when it is reached to the destination, then the process of decoding starts, which is opposite to the encoding and uncompress all the data of video and return the video contents to their original size and order.
