uPnP Fast Forwarding

Description

I'm using a Buffalo Link Theater as a front end. Today I installed SVN 13314. My recordings will now fast-forward, but when I reach the spot I want and hit play, playback resumes at the beginning of the file and not at the point forwarded to.

I have a D-Link DSM-520 and have the same problem. What I have learned is that the device requests a file with an .idx extension that contains mpeg key frame data.

If I use the windows based tools that came with it to generate the file and place it with the original video file, FF works fine. (I changed MythTv? to serve up the file if requested).

I believe that the Buffalo Link Theater may have the same issue.

Until someone with this device can pinpoint the problem and supply a patch, there is nothing that I can do to fix it.

I have the link theater. Please tell me how to generate the logs/where to look, and I'll be happy to do as you ask.

One other note -- I have a uShare server that serves the very same content fine to my Link Theater -- so I don't believe the .idx problem you have with the DSM-520 is relevant. BTW, please tell me how you were able to troubleshoot that? I am willing to help test any possible way that I can -- I just need a little hand-holding.

I've added a copy of the log. During operation, I pressed the FF key, the screen would freeze, the timer would advance six seconds, and then freeze. I then would press the PLAY key, and the video would start over from the beginning. I repeated this a couple of times, then pressed the STOP key.

I can also get a copy of a packet trace, if that would help.

One further note, upon initially browsing the Recordings - All Recordings folder, the Link Theater did not pick up a list of recordings. Only after a couple of tries could I find the files.

I have attached a patchfile that fixes this problem. There was an earlier ticket 2500 which dealt with Content-Ranges for Syabas firmware uPnP devices. I'm not sure whether Avel Link Player really had a problem, but the range code was incorrect. My patch corrects it, and enables fast forwarding.

(In [14250]) * Changed Device Name to start with hostname.

  • Had to disable MSRR Service except for XBox 360 & Windows Media Player (userAgent="Mozilla/4.0" so actually applies to more apps.)
  • Added temporary fix for ps3 seeking/unknown media msg. ( Fixes #3776 )
  • Fixed Music CDS - Albums would always be empty.
  • Had to disable "Recently Added" category from Music CDS until fix can be made.
  • Fast Forwarding works correctly in DSM-520... not sure when this was fixed. ( Fixes #3344, #2500 )
Note: See TracTickets for help on using tickets.
