mp4 chapter support

Postby newbuyer17 » Wed Mar 04, 2009 10:34 am

Hi,
Is it possible to encode mp4 video with the original DVD chapters built into them so the PS3 will recognise the original chapters. Or does PS3 not support chapters like this? Am I stuck with the 1/2/5 minute chapters the PS3 creates itself?

I've done a bit of digging but dont seem to be able to find any recent info on this

Thanks

PS3 does support chapters, just put DVD disc to a player. But if you talk about PS3MediaServer -> dlna protocol -> PS3 streaming, then its an another issue. DLNA protocol has limitations, it's a single file streaming. There is no a concept of chapters in dlna protocol. We have available what dlna engineers put together PS3 must feel the pain just like any other dlna client device.

DLNA=Digital Living Network Alliance, a consumer electronics industry standard put together by many companies.

OK, Thanks. Taking the question away from streaming, is it possible to embed chapters in an mp4 file that the PS3 will understand, assuming that the file is physically copied to the PS3 rather than streamed, or will it not read chapters out of mp4 files at all?

No it does not work that way in DVD either. It has a pre defined folder structure to tell metadata. Streaminig a single .mp4 video file lost all that metadata and PS3 just see a stream of ARGB pixel bytes (+audio) to be rendered on tv screen.

DLNA can only stream that given single file, unfortunately it even cannot provide an external .srt subtitling files. Eeasy cake for PC standalone players they see the entire disk system as they please. Someday maybe dlna is extended to have more features but knowing consumer electronics specs evolution speed, don't hold your breath.
