MTV Video (.AMV)

MTV Video (.AMV) is one of a pair of related video file formats that go by a virtually identical set of names. The formats are associated with some Chinese portable video/music players. This article covers the one whose file extension is usually .AMV, and which begins with a "RIFF" signature. For the other one, see MTV Movie (.MTV).

Format details
An .AMV file looks like it uses RIFF, but it is not valid RIFF. It is like a cheap knock-off of AVI.

Identification
.AMV files start with ASCII "", have "" at offset 8, and (usually?) bytes at offset 4.

Software

 * FFmpeg (Classifies the format as AVI.)
