View Full Version : Optimising MP4 streaming to PS3

Hi,

Hopefully I've posted this in the right section, apologies if not.

I've recently been trying to stream some content to a PS3 via a proxy and have observed some behaviour that means that the stream doesn't play until the whole file has been downloaded.

In the cases I've observed, the MOOV atom is at the head of the file so this is not the issue. Analysing the requests the PS3 is making shows that after receiving the MOOV atom it asks for a chunk of data at the end of the stream, within the MDAT atom but I have no idea why it's doing this? For a stream of about 25MB, the PS3 is asking for approximately 100KB from the end of the file. For a file that's approx 1GB, the PS3 is asking for a chunk of about 1MB.

Does anyone have any ideas what the PS3 is doing here? Other renderers do not behave like this when playing exactly the same content.

thanks.
