eyed3.mp3 package¶
Submodules¶
eyed3.mp3.headers module¶
-
eyed3.mp3.headers.
isValidHeader
(header)[source]¶ Determine if
header
(an integer, 4 bytes compared) is a valid mp3 frame header.
-
eyed3.mp3.headers.
findHeader
(fp, start_pos=0)[source]¶ Locate the first mp3 header in file stream
fp
starting a offsetstart_pos
(defaults to 0). Returned is a 3-tuple containing the offset where the header was found, the header as an integer, and the header as 4 bytes. If no header is found header_int will equal 0.
-
eyed3.mp3.headers.
timePerFrame
(mp3_header, vbr)[source]¶ Computes the number of seconds per mp3 frame. It can be used to compute overall playtime and bitrate. The mp3 layer and sample rate from
mp3_header
are used to compute the number of seconds (fractional float point value) per mp3 frame. Be sure to setvbr
True when dealing with VBR, otherwise playtimes may be incorrect.
-
class

LameHeader
(frame)[source]¶ Bases:
dict
Read the LAME info tag. frame should be the first frame of an mp3.
