As an example we will use the file with parameters in the screenshots below. Later we will show the location of some parameters of the audio (frame size, sampling rate, channels count, profile) in encoded AAC/ADTS elementary streams.

ADTS header consists of adts_fixed_header and adts_variable_header. High level ADTS bitstream overviewĪDTS header starts with a 12-bits prefix 0xFFF and consists of 7 or 9 bytes.

Also in the article we will show the location of some parameters of the original audio (channel count, frame_size, sampling rate, profile) in encoded elementary audio stream. This article is a high level overview of AAC audio with ADTS encapsulation. LATM/LOAS – LATM provides a method of multiplexing of several AAC streams, LOAS can be used for adding synchronization to LATM packets.ADTS – ADTS header is added to the beginning of each raw AAC block.ADIF – has one header at the beginning of a file followed by raw AAC blocks.For future transport AAC audio can be packaged with different methods: You can select one audio track to convert and optionally include a surround version of the same language (if available).AAC audio compression has been standardized as a part of MPEG-2 and MPEG-4 specifications. MKV2MP4 does not preserve all audio tracks. Some files (that contain too many ref-frames, 10-bit video or are larger than FullHD) will not play on some devices like the PS3 that don't support these features. MKV2MP4 does not do video downscaling, it is not suited for converting HD videos for playback on (old) devices that don't support HD resolutions (like the iPhone 3G(S)). MKV2MP4 even supports generation of files that play with surround on the AppleTV, which has special requirements. If your file contains a surround sound track you can use MKV2MP4 to generate files that play with perfect 5.1 surround sound on your supporting target device. Most subtitles are fully supported as well (see F.A.Q.). There are also options for automatically adding files to the queue and removing them afterwards for batch handling.

You can choose perfect compatibility for files that will play on every MP4 compatible player. MKV2MP4 can convert hundreds of files at once with it easy-to-use queue system and features convenience options for automatically adding many files without any further work. You can choose in the preferences whether you want highest speed for the audio conversion or the highest compatibility.īecause MKV2MP4 just copies the video data into the new container format there is absolutely no loss of quality, the converted files are pixel-perfect copies. MKV2MP4 can convert files so fast because it doesn't re-encode the video data but just copies it into the more compatible MP4 container format. MKV2MP4 is a free app to convert video files in the MKV container format to more compatible MP4 video files.
