Hi,
I have a question about timed metadata in mpeg-ts.
Given a ts with timed-metadata like
http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_16x9/gear1/main.ts
How do I extract the timed-metadata information?
I have tried
ffmpeg -i main.ts -f ffmetadata metadata.txt
Input #0, mpegts, from 'main.ts':
Duration: 00:30:00.00, start: 10.000000, bitrate: 263 kb/s
Program 1
Stream #0:0[0x101]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 22050 Hz,
stereo, fltp, 41 kb/s
Stream #0:1[0x102]: Video: h264 (Main) ([27][0][0][0] / 0x001B),
yuv420p(tv, smpte170m/smpte170m/bt709), 416x234, 29.97 tbr, 90k tbn, 180k tbc
Stream #0:2[0x103]: Data: timed_id3 (ID3 / 0x20334449)
but the text file was empty.
There are timed-metadata every 5sec in main.ts, like:
ID3v2Tag(Id3v2UserTextInformation(TXXX,, *** THIS IS Timed MetaData @ --
00:19:10.0 *** ),)
ID3v2Tag(Id3v2UserTextInformation(TXXX,, *** THIS IS Timed MetaData @ --
00:19:15.0 *** ),)
Next question is; how do I insert a timed metadata at a specific time, ID, and
text?
Options like -metadata TITLE=foo does not seem to do what I want (e.g. I cannot
specify a timestamp).
