Data Streams
Almost any kind of data can be embedded in MPEG-4 Part 14 files through private streams. The registered codecs for MPEG-4 Part 12-based files are published on the website of MP4 Registration authority (mp4ra.org), but most of them are not widely supported by MP4 players. The widely supported codecs and additional data streams are:
- Video: MPEG-4 Part 10 (H.264) and MPEG-4 Part 2
- Other compression formats are less used: MPEG-2 and MPEG-1
- Audio: Advanced Audio Coding
- Also MPEG-4 Part 3 audio objects, such as Audio Lossless Coding (ALS), Scalable Lossless Coding (SLS), MP3, MPEG-1 Audio Layer II (MP2), MPEG-1 Audio Layer I (MP1), CELP, HVXC (speech), TwinVQ, Text To Speech Interface (TTSI) and Structured Audio Orchestra Language (SAOL)
- Other compression formats are less used: Apple Lossless
- Subtitles: MPEG-4 Timed Text (also known as 3GPP Timed Text).
- Nero Digital uses DVD Video subtitles in MP4 files

Famous quotes containing the words data and/or streams:
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
“We shall prepare the coffee of reconciliation through the filter of justice. Through reconciliation, streams of tears will come to our eyes.”
—Jean-Bertrand Aristide (b. 1953)
