Broadcast Wave Metadata not carried over with -codec:a copy

Description (last modified by )
Timecode and Framerate metadata is not carried over when using -codec:a copy from one wav to another. This results in being unable to trim a file and keep the timecode metadata required for post-production.
The metadata is listed in the output section of ffmpeg but not by ffprobe or Davinci Resolve. I have highlighted in bold the differing lines.
Attached are samples of the input and output of the file.

[18:46] <rexbron> what is the ffmpeg ftp server for samples?
Where did you search for an answer? How did you find out about this bug tracker?
Is the problem not reproducible with 1MB wav files?
comment:3 by , 10 years ago
Hi cehoyos,
I found the address and a link to the tracker on the ffmpeg site but but the ftp client complained that files with the same name already existed. It's very likely something on my end but I can't be bothered to mess around and figure it out, hence why samples were uploaded to servers I have.
I do not have access to the recorder, the files were provided to me from a documentary shoot and I uploaded the smallest sample I have. I would expect it to be reproduce able with 1Mb files.
comment:4 by , 10 years ago
Yes, you had uploaded fragments of the original files.
Do you know which parts of the metadata are missing in the output files or are you just guessing that the different metadata in the output of ffmpeg -i is the reason that the output files cannot be used for post-production?
comment:5 by , 10 years ago
The metadata sections that I hilighted are an educated guess, as both FFprobe and Davinci Resolve see frame rate and timecode metadata in the recorder originals and not in files processed by ffmpeg.
It is crucial that the timecode in the BWF is maintained.
