Re: [FFmpeg-user] Specify FC instead of mono‏

2015-10-28 Thread Carles Vila 
Hi, I'm in the same boat. Would be very useful to fix this.

It was mentioned before that Amazon Prime and Google play ask for ProRes
for their VOD platforms.
For the sake of completeness I'd like to add iTunes and Netflix. So it's a
de facto standard for VOD delivery I would say.It all stems from the iTunes
specification
I can share spec docs if anyone is interested

How is this related to the fact that the mov muxer can't 
be told how to mark mono channels in the chan atom?

Ah, I didn't realize mediainfo could spit out details about the atoms.
It can indeed...

If the samples in the mentioned ticket
https://trac.ffmpeg.org/ticket/2865

notably SD_IVTC_8channel_ProResHQ_test.mov (from ffmpeg, incorrect)
and SD_IVTC_8channel_ProResHQ_test_withT3.7.8_labels.mov (from QT Player, 
correct)

expose exactly the same behavior, I can only say this with regards to
the difference of the files (ignoring the developers' analysis of
whether this can be fixed):

I believe the audio channels in question differ as such:
The "C" center channel:

0D38Channels (24 bytes)
0D38 Header (8 bytes)
0D38  Size: 24 (0x0018)
0D3C  Name: chan
0D40 Version:   0 (0x00)
0D41 Flags: 0 (0x00)
0D44 ChannelLayoutTag:  6553601 (0x00640001)
0D48 ChannelBitmap: 0 (0x)
0D4C NumberChannelDescriptions: 0 (0x)

vs.

0D8CChannels (44 bytes)
0D8C Header (8 bytes)
0D8C  Size: 44 (0x002C)
0D90  Name: chan
0D94 Version:   0 (0x00)
0D95 Flags: 0 (0x00)
0D98 ChannelLayoutTag:  0 (0x)
0D9C ChannelBitmap: 0 (0x)
0DA0 NumberChannelDescriptions: 1 (0x0001)
0DA4 ChannelLabel:  3 (0x0003)
0DA8 ChannelFlags:  0 (0x)
0DAC Coordinates (0):   0.000
0DB0 Coordinates (1):   0.000
0DB4 Coordinates (2):   0.000

Similar for the two other channels: QT seems to use "ChannelLabel" (3
here, 38 and 39 for the two others channels in the sample), which
ffmpeg does not. (Those two are different from your samples anyway,
ffmpeg detects them as DL and DR instead of "downmix".)

I have no idea how to fix this and won't dive into it either. ;-)

With my means and the (very) little knowledge of the MOV format I have,
I couldn't yet detect the difference in those files. I suspect it's in
the atoms, perhaps. Unfortunately, AtomicParsley can only dissect MP4
files, not MOV files.

You can only hope someone else with more knowledge of the format has a
look.

A good summary of this issue, together with samples, would be good in

Can you please provide a very short file with a similar/identical

incorrect ones, while you're at it.)

Hi Carl, related to the same issue is this here:

https://trac.ffmpeg.org/ticket/2865#comment:9

Same as my requirement, in that channels 7+8 are separate mono's, instead of a 
stereo. In this case ffmpeg is not able to flag the mono channel 7 and mono 
channel 8 as DL and DR respectively. So when delivering to the VOD platforms, 
if you are delivering 8 mono's then this would also become an issue. Currently 
ffmpeg can flag 7+8 as DL+DR if 7+8 is a stereo, but not if they are mono's. 
Thought it was worth mentioning here, just in case.

Kind regards.

Hi Carl, thanks for replying.
We deliver Quicktime Prores files with embedded audio to various VOD platforms 
that MUST be labeled in this very specific way, if any channels are named 
'mono' then they fail the file.

Kind regards.
