next ffmpeg code sync

[al3...@googlemail.com]

Hi,
I'm using ffmbc in libquicktime to do prores encoding/decoding, I'd rather use ffmbc (better format support).
But the libquicktime codecs require a newer version of ffmpeg than ffmbc is currently tracking, is this likely to change in the near future, if so any idea when, obviously ffmpeg has support now for a few things that ffmbc doesn't, and would be nice to only have to deal with linking against ffmbc.

cheers

I second this .. FFmbc isn't updated for a very very long time.

Only specific features will be backported. There has been so much bloat
in FFmpeg these past 6 months that it would jeopardize the stability.

OK, I understand but why do you not update all other 'specific' things? 0.7rc7 is almost one year old.

What do you need updated ?
Some issues will be addressed soon and some features will be added.

I agree with Baptiste that ffmpeg is a bit mess and syntax is changing too often.
The ffmbc looks very stable and easier to use compared to ffmpeg.

Sometimes I need to convert from file formats not supported by ffmbc
but ffmpeg did open thoose.
Can't remember what exactly, but it did happen several times.
Should start keep a list on theese.

May be including more decoders is good idea.

What is particularly bloated? Is it mostly stuff from merges?

[Baptiste Coudurier]

That's one problem, yes.

I never experienced that. Your computer is probably too slow ;)
Nonetheless it could be an interesting feature

Some that come to mind:

- Metadata handling. There are plenty issues/bugs with 0.7rc7 .Using Metadata with FFmpeg is flawless (most certainly from 1.0 and upwards)

- Up-to-date filters

- Alac (and FLAC) codec up-to-date with FFmpeg

This is not what I hear from other people.
What are the issues and please report them in the bug tracker.

Which ones ?

I don't think this will be backported at all unless sponsored.

It seems you would be better off using FFmpeg overall, why are you using FFmbc ?

[pete.ma...@gmail.com]

Metadata:

There are a lot of inconsistencies. For example using Album performer does change different metadata in different codecs. Look at ffmpeg, it does it correctly.

Filters:

For example the audio syncing filters.

Why I do not use FFmpeg?

Well, FFmbc has support for several pro codecs (FCpro), can add APIC (pictures) to mp3, aac, alac, .. , ..

Hi everyone,

my wish list for 2013 and beyond..

- Support EBU R128 audio normalise, Mono, Stereo & 5.1
- Timecode copy from source
- Support MXF OP-ATOM (mainly for Avid)
- Gamut limiting
- H265

Regards Rens Dijkshoorn

Pete,

What's "Album performer" ? Album artist ? It works well in Quicktime/iTunes for mp3 and m4a.

If you are referring to ogg/flac then it could be buggy but I don't think I will fix it unless sponsored,

I will accept patches though.

I don't think audio syncing filters are needed currently, -async works well.

Rens,

MXF OP-Atom should be supported already. Do you have files that do not work ?

Hi Baptiste,

sorry for the confusion, wat i wanted to suggest is transcoding from any format to an Avid compliant set
of OP ATOM audio and video files maybe with a command like "-target imx50 -f avid"
