Audio formats in input video containers
Note
Microsoft Stream does not support audio-only media files.
Microsoft Stream supports carrying the following audio formats in input video containers:
- MXF, GXF, and QuickTime files that have audio tracks with interleaved stereo or 5.1 samples
- MXF, GXF, and QuickTime files where the audio is carried as separate PCM tracks but the channel mapping (to stereo or 5.1) can be deduced from the file metadata
