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

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

Software

 * FFmpeg (Classifies the format as AVI.)
