Detailed description

./signal-back_linux_amd64 format -f CSV -o backup.csv BACKUP_FILE
gives me just one-line CSV with the header, no messages. Exporting media files works ok. Check command claims everything is OK. I do not have any SMS/MMS in Signal.

Full relevant output

same problem under windows
.\signal-back_windows_amd64.exe format -m mms -P password.txt -o backup.xml signal-2021-08-02-19-43-25.backup

i have only xml headers without error

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<?xml-stylesheet type="text/xsl" href="sms.xsl" ?>
<smses count="0"></smses>

Same here.. check says "Backup looks okay from here.", no errors is printed, yet the csv/output file only contains the headers. (v0.1.6)

Same issue here. I used this this tool instead: https://github.com/bepaald/signalbackup-tools

Unfortunately, it does not support MMS exports to XML yet.

I have the same issue when trying to export to CSV on Linux with the AMD64 binary. When I add the -v flag to get verbose output, I get no output at all until it just says Killed.

The backup file I am trying to process is close to 4GB.
