Please add 24 bit audio encoding support #47

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello.
I'm using xvid4psp5 for quite some time but sadly it still lacks support for 24 
bit audio encoding.
It can't encode FLAC 24bit audio and the WAV 24bit audio doesn't work (it's 
16bit tagged as 24bit).
That's because it's using ffmpeg for audio encoding, and ffmpeg doesn't support 
24bit audio.
Lots of BDs have 24 bit audio now, so I'm asking you if you could implement 
LIBAV for 24bit audio encoding instead of ffmpeg.

Thanks for your reply.

Hello,

It's me again, seems that the latest FFmpeg revisions now support 24 and 32 bit 
audio files.
http://ffmpeg.org/trac/ffmpeg/wiki/audio%20types
https://ffmpeg.org/trac/ffmpeg/ticket/210
So, I was wondering if it could be added to the next xvid4psp version too?

Thanks

Hello.

I know, but recent FFmpeg\avconv builds requires various changes in XviD4PSP, 
otherwise they aren't compatible. Also 24-bit support isn't there not because 
FFmpeg (in the past; for FLAC) can't handle it, but for other reasons. So, I 
can't promise you anything..

Thanks for your reply.
Problem is when I've to trim videos then it becomes complicated. Because then, 
I've to also use megui to make a trim of the audio (which isn't the best 
solution and not always accurate) and then use the audio copy function in 
xvid4psp.
And lately more and more BDMVs needs to be trimmed, because they merge all 
episodes in one single m2ts.

Another bug in xvid4psp's ffmepg.

2.1 LFE track get encoded as 3.0 Center track.
The channel mask doesn't get preserved.

the latest LAV revision now reads the flac channel masks, that's how you can 
see the order wasn't preserved

Currently XviD4PSP 5 doesn't bother about channel layout at all! It gets 
n-numbers of channels from the decoder (not looking at the layout) and simply 
piping it into encoder, without any explanation how to treat them. Currently 
used downmixing filters (n->2) also not layout-aware, so downmixing can be 
broken\incorrect too. This part really must be "fixed" and\or configurable 
somehow. But really, currently I don't want to do it.. Like other things too, 
because I'm not with XviD4PSP right now and can't suppose when I will be in the 
mood for developing again :) .

I usually use xvid4psp version 6 for audio stuff, try that.

Thanks but that won't work for trims and cuts.
