This tools allows to add timed metadata into transport stream. Metadata are inserted through ID3v2 tags.
Tools based on https://github.com/dusterio/hlsinjector project and MPEG::ID3v2Tag perl package.
To insert timed ID3v2 tags use the mpeg_id3v2_injector.sh scrit. Script will insert Id3v2 TXXX and/or TIT2 tags into the given TS.
# ./mpeg_id3v2_injector.sh -h
Usage : ./mpeg_id3v2_injector.sh -s <transport stream name> -i <ID3v2 file:time> -p <providerID> -a <assetID> -t <time> -d
MPEG2-TS ID3 timed metadata injector.
OPTIONS :
-h displays this help
-s transport stream name
-i ID3v2 filename and time to insert. Several entry can be given separator is ",".
-p provider ID
-a asset ID
-t time in second
-d to enable debug mode
Examples :
#To insert title with an existing ID3 file
./mpeg_id3v2_injector.sh -s test.ts -i test.id3:0
#To insert several titles with an existing ID3 files
./mpeg_id3v2_injector.sh -s test.ts -i test.id3:0,test2.id3:10
#To insert several title without an ID3 file.
./mpeg_id3v2_injector.sh -s test.ts -p test.com -a ad0
-t 0

Given a transportream fileSequence0.ts to add TXXX ID3v2 tag with string "test.com/ad0" use this command :
# ./mpeg_id3v2_injector.sh -p test.com -a ad0 -t 0 -s fileSequence0.ts -d
