Yesterday I noticed that the timing offset is not fixed but depends on
the recording (e.g, with my previous experiments I hardcoded a 4 seconds
delay for the bbc channels, while yesterday I needed a 2 minutes delay).
I don't know the cause of this offset (ProjectX or the crappy media
player of my tv) but the problem can be easily solved with Subtitles:
I now know the cause of the offset, but I don't know how to (easily) fix
it: Project-X for some reason (maybe a wrong option I gave?) doesn't
extract the pts from the video stream, so it doesn't synchronize the
subtitles to the video but it simply assumes the time starts with the
first subtitle.
If, e.g., the first subtitle appears 3 minutes into the recording, it
will get a timestamp of 0 seconds so it will show 3 minutes early.
These are the options I'm giving to Project-X (via its ini file):
# Application
Application.Agreement=1
Application.OutputDirectory=/temporary/word/directory
# CollectionPanel
CollectionPanel.CutMode=0
# SubtitlePanel
SubtitlePanel.SubpictureColorModel=UkFreeview(mc)
SubtitlePanel.enableHDSub=1
SubtitlePanel.exportAsVobSub=1
ExportPanel.Streamtype.MpgAudio=0
ExportPanel.Streamtype.Ac3Audio=0
ExportPanel.Streamtype.PcmAudio=0
ExportPanel.Streamtype.Teletext=0
ExportPanel.Streamtype.Subpicture=1
ExportPanel.Streamtype.Vbi=0
Any hint on what option I could try to get the video pts (but only the
pts, I don't want to extract the video stream)?
Or simply Project-X cannot do it with h264 streams?
Bye
