when use fmp4 segment type in hls and use codec copy,
there have an error message.
error message:
[mp4 @ 0x25df020] Tag avc1 incompatible with output codec id '28'
([33][0][0][0])
[hls @ 0x2615c80] Some of the provided format options in '(null)' are not
recognized
Could not write header for output file #0 (incorrect codec parameters ?):
Invalid argument
this patch can fix it.
