Any file over 4 GB appears as corrupt data to the PS3.

All files under 4 GB play fine.

Not sure if it is a MediaTomb or PS3 limitation.

    what is your system? I know we do have some warnings on amd64, so would be interesting to know what system you have.

    I think we could check that, several options:
    1. does streaming of >4GB files work from other servers?
    2. in the web UI of MediaTomb, locate the file in question, copy paste the link and wget the file, after that compare md5sums of the downloaded vs. the original file - do they match?

    if 1. fails - probably PS3 problem
    if 2. fails - MediaTomb problem (this has been tested with 20GB files, but not on amd64)

    if the cases above succed, we can do a 3rd test
    3. a special case to test range requests, this will be a little complicated so I'll have to come up with something :)

    thanks,
    Jin

    This happens with both 0.9.1 ubuntu binary and with SVN compiled today.

    My system:

    Linux ubuntu 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007 i686 GNU/Linux

    model name : Intel(R) Pentium(R) 4 CPU 3.20GHz

    1. I don't have any other server that works.

    2. Downloading the file in question with wget and md5sum works as expected.

    It could be a PS3 problem:

    According to that post MP4s > 4 GB show as unsupported, but for me they show as corrupt. The PS3 attempts to start the video, some network activity occurs, and then it craps out.

    According to some more Googling, MPEG2 is the only format that works for files > 4 GB.

    So, sorry for the false alarm.

    No problem, too bad that it is not supported :(
    Still happy to hear that it's not a bug in our code :>
