Sample file (100_0423.mov - 3.85 MB): http://www.multiupload.com/JG79LFUE8X
4) For the uLaw audio in this file MediaInfo and VLC report 16-bit while the input plugin in File => File information report 8-bit.
Also in Audio => Conversion => Precision there aren't the bit near "No change"
5) Just a minor thing, the audio duration is 16.024 for MediaInfo while it is 16.025 for the input plugin in File => File information.
6) I don't know too much how it is working but I'm curious to know why the QuickTime input plugin always return false in IsVBR().

Sample files: (AMR test files.zip - 16.77 MB): http://www.multiupload.com/0P6JQZPQZJ
7) 3g2 file in folder 1 => Unsupported ftyp major_brand: '3g2b'
8) 3gp file in folder 2 => Unsupported ftyp major_brand: '3gp6'
9-10) The AMR-WB I think is for AMR-NB like HE-AAC for AAC, so maybe you can reuse some existing code of AMR-NB for AMR-WB.
AMR-NB => "Sampling frequency 8 kHz/13-bit (160 samples for 20 ms frames), filtered to 200–3400 Hz.", probably only mono
(I have some samples of 3gp files that report 48.0 KHz but they are 8 kHz)
AMR-WB => "All modes are sampled at 16 kHz (using 14 bit resolution) and processed at 12.8 kHz.", "3GP also allows use of AMR-WB bit streams for stereo sound"
In the folder 1 there is "H.264 + AMR-WB.3g2" and the remuxed version "H.264 + AMR-WB.avi", also there is the extracted audio "AMR-WB.amr".
11) Maybe show also the sample precision in File -> File information that I suppose is fixed (13-bit for AMR-NB and 14-bit for AMR-WB).

I'm no expert but my understanding is that the samples encoded by aLaw and uLaw are always in the 8-bit range (0 - 255). The Windows codecs will only accept 8-bit audio for compression, so I presume their output is 8-bit as well.
| QUOTE | | Also in Audio => Conversion => Precision there aren't the bit near "No change" |
I don't see this in VirtualDub 1.9.11. Mine says "No change (8-bit)".
| QUOTE | | 5) Just a minor thing, the audio duration is 16.024 for MediaInfo while it is 16.025 for the input plugin in File => File information. |
The count of samples is 192294, and the rate is 12000 samples per second. So 192294 / 12000 = 16.0245. The plugin is only accurate to milliseconds so the number is rounded up to 16.025. I've no idea what MediaInfo does.
| QUOTE | | 6) I don't know too much how it is working but I'm curious to know why the QuickTime input plugin always return false in IsVBR(). |
As I understand it, returning true causes VirtualDub to invoke the plugin's TimeToPositionVBR() and PositionToTimeVBR() methods when seeking. This is necessary if the audio blocks have variable durations (as in WMV) but it isn't needed here. All of the audio codecs I support are composed of blocks of the same duration.
On the other hand, it is vitally important to specify kFlagVariableSizeSamples in the AudioSource's GetStreamSourceInfoV3() method if the audio blocks vary in size. The plugin flags this condition as QTT_IS_VBR (a misnomer, since it doesn't actually indicate VBR audio) and it is quite common. Support for variable size audio blocks was added in VirtualDub 1.8.8, which is why that version is the minimum required for the plugin.

VirtualDub 1.9.11 is wrongly reporting 8-bit in many cases, try with VirtualDub 1.10.1 test 18.

So your plugin is right but MediaInfo probably is truncating instead of rounding.

Version 1.9 is up. AMR-NB and AMR-WB should mostly work, based on the three samples I have seen.

You'd have to ask Avery, but if he is not showing the bits per sample then I would guess that it is because the audio is a compressed format. Bit depth doesn't really apply in that case.
I was wrong about Microsoft's aLaw and uLaw codecs, by the way. They actually require 16-bit samples, but they are compressed to 8-bit samples; i.e., these codecs have a fixed 2:1 compression ratio.

Hello,
....maybe a stupid question :
-I have installed the latest version of this plugin, and am using VD-1.9.11.
-I "open file" a .mp4 fila that is H264 encoded.
The file does load in VD, but the frames are all black ??? (the original movie is of course not all black when watched in QT).
... certainly something stupid I am doing/not doing ?
Thanks for the help,
sgu |

If all frames are black probably you are using the MP4 input plugin by SEt instead of the QuickTime input plugin by fccHandler.
Remove the first from the plugin folder.

@fccHandler: I think that just mp4v and mp4a are used for many formats.

.... no, I do not think it is this.
... I have removed all the .vdplugin file from the "plugin" and "plugin32" folder (I had ffdshow + other encoder/decoder there) and just left the "QuickTime.vdplugin" in this last folder, even restarted the PC ... still the same... I do only see back frames ....
any other ideas ?
Thanks,
Stephane |

Does it support "private track ID"?
| QUOTE | 4) Is it also possible to place streams not covered by the MPEG-4 standard in MP4?
...
the MPEG-4 standard defines how to place any stream in MP4. Similar to how streams are marked in AVI with private FourCCs, in MP4 they get a "private track ID".
...
the following streams, not covered by MPEG-4, can be placed in MP4 already:
- Ogg Vorbis and Ogg Theora, via MP4Box
- Ogg Vorbis, via a patched mp4creator
- Apple's Lossless Audio (ALAC/ALE - not compliant with MPEG-4 ALS), via iTunes
- DVD picture subtitles (Vobsubs), via Nero Recode2 |
It will be nice to also show the "private track ID" in File informations.

Would it be possible for your plugin to load Flip UltraHD files?
Here's a sample clip from the Flip:

I have been using your plugin for Kodak ZX1 .MOV files and it works great. There is no AAC stuttering and repeating in finished encodes to other audio formats. |

I've uploaded version 2.0 of the QuickTime plugin:
http://fcchandler.home.comcast.net/Plugins/QuickTime
I updated its copies of the plugin SDK include files but did not add any support for new colorspaces yet.
To rjisinspired, I added the 'MSNV' ftyp, and I also added code to check compatible brands when the major brand is unknown. This should help a lot to reduce unknown ftyp errors in the future.
To ale5000, I added parsing of the 'pasp' atom but I have no idea if it is correct. Unfortunately I never got your sample and the link is dead now.
Regarding "private track IDs" in MP4, I can't find any official documentation about it and I don't know what field they are referring to. I presume this is something different from the Track ID field in the 'tkhd' atom? (That one is just a 32-bit int, and there are no restrictions on it except that it cannot be zero and must be unique.)
In the Doom9 FAQ he goes on to say that "no player will be able to handle such streams in MP4, but will simply ignore them, if not explicitely specified to do so." Based on that statement, this sounds like something messy that I might not want to get involved in.
