-metadata track=1/10 and M4A issues

Description

Adding metadata track total to .m4a files does not work anymore with FFmpeg 1.1 and higher (gits)

ffmpeg -i source.mp3 -c:a aac -strict -2 -metadata track=1/10 -vn -output.m4a

It only adds the track number (1) but not the track total number (10)

Works fine with FFmpeg 1.0.1

comment:1 follow-up: Changed 4 years ago by Atarikid

To be more clear:
-metadata track="1/10" should save "1/10" to TRK but in only saves "1"

comment:2 in reply to: ↑ 1 Changed 4 years ago by cehoyos

Replying to Atarikid:

To be more clear:
-metadata track="1/10" should save "1/10" to TRK but in only saves "1"

To make this clear you could add the output of "ffmpeg -i output.m4a"

And please add the complete, uncut console output for your original, failing command line, never cut the first 50 and the last 50 lines.

comment:3 Changed 4 years ago by cehoyos

And since I am unable to reproduce the regression (ie that it worked with earlier versions):
Please also add command line together with complete, uncut console output for a working version.

comment:4 Changed 4 years ago by Atarikid

BTW it works fine for MP3 but for M4A (AAC and ALAC) it does not work.

comment:5 Changed 4 years ago by Atarikid

Hmm.. strange .. It does not seems to be a regression after all (although I was pretty sure it worked fine with FFmpeg 1.0)
Anyhow, it should do it. It does with all other formats.
Or is there another metadata for track total?

comment:6 Changed 4 years ago by Atarikid

Some more info:
I just compiled ffmbc and it works fine.

comment:7 Changed 4 years ago by cehoyos

  • Component changed from undetermined to avformat
  • Version changed from unspecified to git-master

Could you add the complete, uncut console output (including command line) for your failing command to make this a valid ticket?

comment:8 Changed 4 years ago by Atarikid

Ok here follows all information I can give you - including how it works fine with mp3 and a example file.

First let us show how it should work.

As you notice the track metadata reads 1/10 as it should.

At least one output file must be specified

The track metadata is now only 1 which is not correct.

Notes:

  • It doesn't matter if you use aac, libfaac or any other aac encoder.
  • This issue also applies to ALAC encoding
  • All other codecs (ogg, wav, opus, ... ) it works fine as with mp3. So its only a .m4a issue

Hopes this helps fixing this.
