'Bug' report / feature request for the 'File Integrity Verifier' extension

2023-04-18 17:45:57

While playing around with ffmpeg and looking for a format to store large uncompressed audio files over 4 GiB, I happened to find a small problem with the RF64 format (a subset of BWF).

It looks like the 'ds64' extension in the header for files over 4 GiB of the RF64 format has not been taken into account yet.?

Currently in use under Windows 10:

Core (2023-01-13 20:48:54 UTC)
foobar2000 core 1.6.16
foo_verifier.dll (2022-02-06 21:40:24 UTC)
File Integrity Verifier 1.4.2

To reproduce:

Code: [Select]

>ffmpeg -f lavfi -i sine -t 50ms -c:a pcm_s16le -rf64 1 -y 50ms.wav

>hexyl -c 0x80 50ms.wav // (original header from ffmpeg output)

I have looked around a bit and found this about the RF64 format:
https://en.wikipedia.org/wiki/RF64

The last and updated recommendation for RF64 (subgroup of BWF), nicely titled:
'Long-form file format for the international exchange of audio programme materials with metadata'
Page #7 (self numbered as 5)
https://www.itu.int/dms_pubrec/itu-r/rec/bs/R-REC-BS.2088-1-201910-I!!PDF-E.pdf
(Thanks to the good output I could then get from the 4294967295 bytes (0xffff ffff) to the -1 as Int.)

and here also in other languages:
https://www.itu.int/rec/R-REC-BS.2088-1-201910-I/en

Sorry, it almost became a short novel. (;

Thank you and best regards.

PS: And of course thanks for the time and the wonderful player foobar2000 with its solid features and all its extensions.

Here again a small update:

Uhm, not beautiful. It seems that ffmpeg then writes over 4 GiB only a very reduced header.

Unfortunately I had not tested this before, sorry for that.

But the good news is that the test is terminated without warning by the extension.

I hope I didn't waste too much of your time. ):

I don't know if the attached files are actually valid BWF/RF64, but WavPack handles them just fine, and WavPack has a habit of doing things right.

fb2k's integrity verifier is not that happy.

Files are 32-channel sine, 10 seconds, got them from
https://www.lynxstudio.com/downloads/aurora-n/sample-wav-file-zip-encoded-1khz-sine-wave-32-channels-44-1khz-bwf/
https://www.lynxstudio.com/downloads/aurora-n/sample-wav-file-zip-encoded-96khz-pcm-24-32-channels-rf64/
and xz'ed them down to virtually nothing.

Acknowledged, thanks for reporting.

Thank you for your work and time. All my RF64s have passed the integrity test of the files with the current beta of Foobar2000. (foobar2000 2.1 preview 2023-11-27 - 32bit)

The following refers to the above mentioned version with a fresh installation of the 32bit edition (foobar2000 2.1 preview 2023-11-27 - 32bit):
While playing around, I discovered a few problems with the Wav decoder, Foobar's internal type recognition, the integrity test and the tag transfer.
This mainly concerns the problem with the 4-GiB limit of wave files. The decoder seems to recognise the limit quite late (sometimes only when it wants to transfer the tags) or the files are converted correctly at the edge of the 4 GiB limit, but Foobar does not recognise the file as valid.

Re: 'Bug' report / feature request for the 'File Integrity Verifier' extension

RF64 issue that might be ffmpeg:
fb2k doesn't seem to be happy with ffmpeg-generated RF64 that contain floating-point PCM. An example uploaded at https://hydrogenaud.io/index.php/topic,123862.msg1036400.html#msg1036400

@Decaf5192 that might be relevant to you as well?

Not RF64, BW64. Which isn't RF64 even if the Wikipedia page says so. Corrections over in that thread. My bad.
