Hi,
I'm working on a video editor that uses ffmpeg to encode output renders and
I'm having some trouble properly tagging .mov files. Specifically I want to
set the nclc color tags so that QuickTime and other players will properly
display the files.
If I generate a file with the following ffmpeg c

But I do not have a solution how to do it exactly, it may also depend on the

A long time a go I'd had a ffmpeg project and I must also put some extra data

Yes.
My file is H.264 and I do not transcode anything.
Is there any way to send packets with payload different to 96 without
transcoding ?
No, for H.264 you have to use a payload ID from the dynamic range.

If you can playback or re-encode an iPhone video, then yes. MOV/MP4 is
_not_ a fixed frame rate format. In other words, there is no "FPS"

I have built older versions of ffmpeg on my Windows system using MinGW, but
the latest snapshot refuses to build.
After a bit of fuss I got a configure command to (almost) run to

I know the interface between libavcodec and libx264 is such that you can
pass at least some of the native x264 option strings, such as preset names,
through the opts argument to avcodec_open2(). However it also appears that
this is not enough to put the codec into a usable state.

What has changed in the past couple months that would cause
av_read_frame() to return negative values well before the end of the
file if thread_count is set to 1 for the video? This is the behavior I
get with both MOV and MTS files with H.264 compressed video. If I set

I posted this on the FFmpeg list, but got no reply. This is take two.
I'm having trouble controlling timing values written to MOV files.
Things like timescale and duration values written to the tracks differ
from what I'm supplying in the AVCodecContext timescale parameter. For
example, if I speci
I am playing around with multithreaded H.264 decoding with git from a
few days ago, but I noticed that frames are returned with a delay
equal to the number of threads assigned to the decoder context. The
way I can tell if I am getting decoded frames is by checking
got_picture_ptr, which works even
DNxHD 444 has been mentioned quite a few times around L.A. Are there
any plans to support it in Libav/FFmpeg?

I'm happy to see that ProRes decode support is now available. That's
awesome. What's the difference between the GPL and LGPL versions?
The only difference I can see (from avconv -codecs) is one supports
"direct rendering method 1" and the other doesn't. That same one is
labeled "iCodec Pro."
Anxi
