while i am writing a mp3-player, some questions occurred, which i can't solve at my own: (the player should decode "on-the-fly")
1. using a time-bar in my gui, at which the user can jump through the
mp3-file (while playing), the method decodeMP3() in //mpglib/interface.c produces some output
like: "bitstream problem: resyncing..."
or: "big_values too large! 482"
or: "Blocktype == 0 and window-switching == 1 not allowed."
can i ignore this?
is calling lame_decode_exit() and then lame_decode_init() after an user-jump a good idea?
2. positioning through the *.mp3-file on harddisk is problematic. i calculate the byte-file-pointer
from the *.mp3-file-length and mp3data->nsamp. to read the next bytes into my mp3Buf.
should i subtract the mp3-header-length from the *.mp3-file-length to have more prezision?
what else is to do?
3. how to flush samples from decode-internal-buffers at the end of the song?
4. the decode-api offers me "enc_delay" and "enc_padding". what to do with these values?
5. compiling on macintosh os-x, my application often crashes while the lame-internal method
decodeMP3() in //mpglib/interface.c is calling malloc() and free().
any ideas why? the mp3Buf[] and its size are valid. also the pcm_outputBuf[] (left and right).
thx in advance. sebastian roll.
