#4704 closed enhancement (fixed)

Timecode data not maintained when using mp4 wrapper instead of mov wrapper

Description

Summary :

Working with a quicktime mov with timecode embedded.

  • When an output is created with a .mov wrapper the timecode value is maintained
  • When changing the output file to have a .mp4 extension the timecode value is not maintained.

Timecode in mov output is located at the following location :

Metadata: handler_name : DataHandler?
timecode : 01:00:00:00

Below are both calls for creating the output files as well as both calls for reading the metadata values.

Timecode Test Files ( input and outputs )

comment:1 Changed 4 years ago by alan1523

  • Type changed from enhancement to defect

Reading into the logs further , when the system outputs the .mp4 file its saying it will write a metadata value for the timecode value on Stream #0:0(eng): , but that metadata value is not maintained.

"excerpt" below from ffmpeg creation command stated in previous thread :

Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 720x576 [SAR 59:54 DAR 295:216], 180 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default)
Metadata:
handler_name : DataHandler??
encoder : Lavc56.46.101 libx264
timecode : 01:00:00:00

  • Component changed from undetermined to avformat
  • Keywords mov added

As you correctly report, mov files do / can contain a timecode track, isom files do not contain such a track.
What issue do you see that can be fixed in FFmpeg?

comment:3 Changed 4 years ago by alan1523

Yes, indeed it is not standard to have timecode track in mp4 files, there is although a Technical note from Apple on how to handle timecode in this case. If time permits it would be nice to review the feasibility of this implementation.

https://developer.apple.com/library/mac/technotes/tn2174/_index.html#//apple_ref/doc/uid/DTS40014018-CH1-TNTAG14

I will see if there are some sample files from Final Cut Pro X with mp4s and timecode.

I also can reach out to the Apple FCPX development team if need be.

comment:4 Changed 4 years ago by cehoyos

Please provide a sample file.

comment:5 Changed 4 years ago by alan1523

Here is a link to a sample mp4 file with timecode embedded.

This file was produced by the Apple Final Cut Pro team.

Let me know if you have any questions.

comment:6 Changed 4 years ago by cehoyos

  • Priority changed from normal to wish
  • Status changed from new to open
  • Type changed from defect to enhancement
  • Version changed from unspecified to git-master

comment:7 Changed 3 years ago by andaleeb

I had sent a patch for this to ffmpeg-devel mailing list a couple of weeks ago, but I did not get any response/review for it:
Mail: http://ffmpeg.org/pipermail/ffmpeg-devel/2016-January/187596.html
Patch: http://ffmpeg.org/pipermail/ffmpeg-devel/attachments/20160121/4c46f63b/attachment.obj

comment:8 Changed 3 years ago by cehoyos

  • Resolution set to fixed
  • Status changed from open to closed

I believe this was fixed by Syed Andaleeb Roomy in b4dcd351ec50caaa484bc5c66b4a8d5557a0f1ea

comment:9 Changed 3 years ago by blacktrash

Why not use -copy_unknown for this? - see: #5492
