 I have found out that ffmpeg or ffprobe recognize avi metadata tags only
 when avi RIFF structure is in special order:
 (attached file test2.avi)
 1. RIFF AVI
 2. LIST hdrl
 3. LIST INFO
 4. LIST movi
 5. idx1

 if the order is different then INFO tag is not recognized and metadata are
 not read, for example with following order:
 (attached file test1.avi)
 1. RIFF AVI
 2. LIST hdrl
 3. LIST movi
 4. idx1
 5. LIST INFO

 It will be great if some future version will be able to read metadata from
 any position in AVI.

 I have attached also a picture with structures of both files
