1. What is ADTs? The full name of ADTs is (Audio Data Transport Stream), which is a very common transmission format of AAC. Remember that when Demux is used for the first time, when the es stream of AAC audio is extracted from the FLV Encapsulation Format and sent to the hardware decoder, it cannot be played. When it is saved to a local PC player for playback, I cannot play it either. At that time, I collap

Before the introduction of decoding AAC, once used Fadd, and mentioned, if you want to encode into AAC format, you can use FACC, FDK-AAC, etc., but the use of FDK-AAC and other encoding methods, are soft coding, CPU consumption will be significantly larger than the hardware code.The hard-coded advantage is the ability

framethe frame type for the second frame is: 0x68 0x1F = 8, which is a PPS framethe frame type for the third frame is: 0x06 0x1F = 6, which is an SEI frame The above is the use of frame qualifiers to divide frames, and to determine the type of each frame. Note: If the image is compressed into a H264 frame, we do not have to frame, because each compressed output is clear the size of the frame (including the qualifier), each time the result of the compression may be multi-frame function.

AAC (Advanced Audio Coding), known in Chinese as "Advanced Audio Coding", appeared in 1997, based on MPEG-2 audio coding technology. By Fraunhofer IIS, Dolby Laboratories, Att, Sony (Sony) and other companies to develop together, the purpose is to replace the MP3 format. In 2000, after the MPEG-4 standard appeared, AAC integrated its characteristics, adding SBR technology and PS technology, in order to dist

This article introduces a small open-source project: AAC format analyzer. The full name of AAC is Advanced Audio Coding, which is a widely used Audio encoding format on the Internet and the best Audio encoding format at present. A large part of existing videos on the Internet use AAC for audio encoding. Developed Using MFC of VC 2010. Faad2, an open source decode

In the previous article, we used ffmpeg to separate the audio and video data from a multimedia container, but it is possible that the data could not be decoded correctly. Why is it? Because the decoder needs to be configured before decoding the data, it is typical of the current popular HD coded "Golden Partner" combination H264 + AAC . This article will describe the key decoding configuration parameters of H264 and

The feature of this format is that it can be determined to find the beginning of this audio data, without the need to start

AAC ADTS LATM format Analysis one, Adts format : The full name of Adts is the audio Data Transport Stream. is the transport stream format for AAC audio. The AAC audio format is defined in MPEG-2 (ISO-13318-7 2003). AAC was later adopted in the MPEG-4 standard. 1. Adts_sequence () { while (nextbits () = = Syncword) {
