Sony UPNP BDP-S570

[b.rumple@…]

I recently got a Sony BDP-S570 blu-ray player and wanted to connect it to MythTV. Right off it won't even discover myth, so I did some searching and found minidlna. Ran minidlna and the player connected just fine and was able to play videos. This made me curious about what was happening with myth so I traced the packets and found that the request SOAPACTION: "urn:schemas-upnp-org:service:ConnectionManager:1#GetProtocolInfo" returned different protocol information between myth and minidlna. I made a quick change in myth to just use the protocol information from minidlna and now the player will connect to myth. Then I tried to browse and the player said there were no playable videos, so I dug into that. This also turned out to be a protocol problem with the video. I made a quick change to have the protocolInfo always be http-get:*:video/mpeg:DLNA.ORG_PN=MPEG_PS_NTSC;DLNA.ORG_OP=01;DLNA.ORG_CI=0. This allowed the player to play my recordings from myth.

I'm guessing that the protocol information returned from myth is incomplete and the mime type resolution is not granular enough for some players. I realize that the current implementation probably works for many players but it might not be implemented according to spec and will cause problems for newer players?

Ref #9424. Very similar if not duplicate.

The fix for 9424 is a simple hack to force the mime type to video/avi. This works for his Sony player which I think is a BDP-S470, but not for the 570. This ticket is more about making the fix in a more complete way that will hopefully be more generic and support other players in a standard way.

I just got the S570 too and was researching this very issue. I've found a few other details that may be relevant.

Sony's description of the supported formats for the DLNA feature is here ​http://www.kb.sony.com/selfservice/viewContent.do?externalId=C1017936&sliceId=1&mdl=BDPS570

But by modifying minidlna I've learned that it will play both MPEG2 and H264 files the same as via USB as long as the DLNA server says they are one of these types:

• MPEG_TS_SD_NA_ISO
• MPEG_TS_SD_NA
• MPEG_PS_NTSC

To the original poster: Do you have a patch to share? I can look into this, but if there's a patch to start with, all the better.

No patch forthcoming, remove infoneeded tag.

Beirdo, any interest in tackling this for 0.25 now there is a patch?

Fix UPnP for Sony BluRay? players

Set DLNA.ORG_PN=MPEG_TS_SD_NA_ISO for video/mpeg, which allows Sony Blu-Ray players to see recordings.

This doesn't seem to be likely to break other UPnP clients, but as usual, our UPnP Mediaserver support is kinda like black magic not having the DLNA spec, and is based primarily on user trial and error and observations.

Fixes #9446

Let's put this in now, knowing that we might need to tweak again. Coding via trial and error is fun.
