This still leaves cache_aligned_malloc() in
libs/pbd/malign.cc pending _aligned_free (windows crashes when using
free() on memory allocated with _aligned_malloc()).
So far however there seems to be no issue with default malloc
for audio+midi buffers on win32…
This allows to cleanly install 32 and 64bit windows versions in parallel.
Ideally we’d only do that for 32bit builds on win64.
We need an NSIS guru to write code to detect this during installation
and write the correct uninstaller for that case.
1) Disambiguate 1.0 to GAIN_COEFF_UNITY, and 0.0 to GAIN_COEFF_ZERO
2) Add GAIN_COEFF_SMALL which replaces SMALL_SIGNAL (-140dB)
3) GAIN_COEFF_SMALL can used to avoid interpolating towards -inf on a db scale
4) GAIN_COEFF_SMALL is used to detect very small (denormal?) gains and memset to zero
The tool mp4chaps by the following command
$ mp4chaps -i test.mp4
looks for the file "test.chapters.txt" to read the chapter marks
from. So removing the original file name extension (e.g. wav or flac)
makes it slightly more convenient for the user.
Players like vlc seem to stumble, if there es no chapter at the zero
position. As Ardour wouldn't let us put a track mark at the zero
position we can just use our header_func to put some kind of dummy intro
chapter. If a future version of Ardour allows track marks at zero, we
need to do a bit more work.
The mp4 file format supports chapter marks using the so called
mp4chaps format to enable chapter wise navigation in an mp4 file. The
format is like
hh:mm:ss.sss Chapter Title
This commit adds the ability to export those kind of chapter marks
along with TOC and CUE marks. The filename extension for the chapter
mark file is "chapters.txt". The format specification description is
"MP4ch".
Change ruler context actions from "Make Loop range" to "New Loop range"
change ruler context actions from "Make Punch range" to "New Loop range"
This to make it consistent with other ruler context actions eg. "New....."
Copy the 'Cut time' code from Mixbus, making a few obvious fixes to work in
A3 (e.g. nframes_t => framepos_t / framecnt_t).
Seems to work to move & remove markers, tempo & meter markers, and regions on
selected tracks.
Still TODO:
- use existing A3 'Insert time' dialogue
- make it respect 'No selection = all tracks'
- rename the command to something like 'Remove time' or 'Delete time': 'Cut'
sounds to me as if the removed range should end up on the clipboard ready
to be pasted somewhere, which of course it doesn't.
[Details] This bug does not show up when buffers are 16 byte aligned, but when they are not - this bug will lead to crash.
I tested all these functions with non-aligned buffers as well as long they do handle the situation with unaligned buffers.
