#693 closed patch (fixed)

PATCH: mythtranscode compile fix

Reported by: gkruse@… Owned by: Isaac Richards
Priority: minor Milestone: 0.19
Component: mythtv Version: head
Severity: medium Keywords: mythtranscode osx mpeg2fix compile
Cc: Ticket locked: no

Description

On os x the new mpeg2 code in mythtranscode does not compile for several reasons:

1) malloc.h is not found (doesn't exist and is not needed on osx?) 2) there is no function called open64() on os x (I think this is for large file support however open() seems to work fine on os x) 3) there is no memalign() function on os x because malloc() returns aligned memory by default

The attached patch corrects all of these issues. It compiles cleanly and I have tested it on one recording. It would be interesting to see if it will work on files > 2 gb.

(In [8002]) Close #693, but use av_malloc for aligned mem, and O_LARGEFILE for open.

unfortunately, os x also lacks a O_LARGEFILE definition so this fix doesn't exactly work. (Great OS huh?) I'm pretty sure (TM) that just plain old open works for large files on os x.

mpeg2fix.cpp:284: error: `O_LARGEFILE' undeclared (first use this function)

the open() man page says nothing about large files on os x

(In [8006]) Close #693 again. Forgot to define O_LARGEFILE if it doesn't exist.
