ReadyDLNA/MiniDLNA/UPNPAV/ReadyMedia Problems

I am running the current version--reported as 1.1.0--of the boxed-in DLNA server which comes with RAIDiator 4.2.26 on my ReadyNAS Ultra 6 Plus. Most files stream fine to a variety of UPNP devices, but I am having a problem with some that generate error messages like this in /var/log/upnp-av.log:
[2014/05/08 09:30:01] metadata.c:742: warn: Opening /c/media/FILENAME.mp4 failed! [Operation not permitted]

There is nothing wrong with these files: Other files in the same directory with the same UN*X permissions play just fine. I can play them from mounted shares on a variety of platforms using a variety of software players without problems. It is not a file size problem--some of working and failing files are above or below the 2/4 GByte limit.

Other shows, just as fine using the other methods, insist that they are audio files to the DLNA clients and will not play the video content.

Any ideas?

Would upgrading to the latest ReadyMedia from Sourceforge, which appears to be a little newer, help? If so, what is the most convenient way to get it? If needs be, I can compile it from source, but ideally there would be something easier.

Thanks!

    MP4s (like most container formats) can hold a variety of compressed bitstream formats, and sometimes the details on that matters. Perhaps try a mediainfo analysis? The tool can be found here: http://www.videohelp.com/tools/MediaInfo Select the text view, and cut/paste the data into a reply (hand-editing the file name if you wish).

    Also, if the file name has unusual characters, you could try a test where you simplify the name, and see if that helps.
  • Thank you, StephenB, but I doubt that is it. All the files, both the thousands that work and the dozens that don't, are h264 video (generated by x264), AAC audio, and usually mp4s subtitles. There are no non-ASCII characters in the file names.

    Below are two example mediainfo outputs of the backup of two movies for which I made backups from my DVDs/Blu-rays. Both generate consistently generate the above error in readydlna.

    Thank you, StephenB, but I doubt that is it. All the files, both the thousands that work and the dozens that don't, are h264 video (generated by x264), AAC audio, and usually mp4s subtitles. There are no non-ASCII characters in the file names.
    I hear you. However, one of the challenges with DLNA (compared with CIFS or NFS access) is that both the DLNA server and the DLNA player need to understand the details of the media format. The server needs to be able to demux the container and stream, it also needs to understand adapt to what the player says it can play.

    This makes interop issues hard to diagnose sometimes.

    Anyway, that was why I asked. Your MP4s have a lot more stuff in them than most of mine, but I am not seeing anything crazy in there. Sometimes AC3 audio shows up, and I know that can cause issues with some players, but I'm not sure about ReadyDLNA. The details of the AVC encoding are consistent with the signaled profile/level (which BTW is not always the case).

    I am wondering about the isom base media - is that also showing in other files that do play?

    As far as practical next steps...
    (a) you could try to compare mediainfo data with some similar files that do play, and see if you can discover a signature. That of course is pretty time consuming.
    (b) you could try plex (https://plex.tv/downloads), and see if that works
    (c) you could try remuxing these two mp4s to MKV, and see if that resolves anything.
    (d) maybe PM skywalker, and see if he has any suggestions on ReadyDLNA - including your update idea.
  • Thanks again, StephenB, you're advice is always much appreciated, in this thread as in many others I only read. I understand that these problems are fairly common, but I'm pretty familiar with media file formats, which is why this thing which has puzzled me for years is so frustrating.

    One clarification to my earlier post, is that the video files which in the DLNA clients show up as audio-only appear to be the same ones for which minidlna spits out that error message. That may be a hint, but it hasn't helped me yet.

    As for your suggestions:
    (a) MediaInfo on all the files doesn't show me any hint of why they don't work.
    (b) I'm using Plex on some devices and that--while it has problems of its own--is fine for those devices.
    (c) In the past, I've tried remuxing them as mp4s again with mp4box, without success. I could try mkv, but a bunch of my players only do mp4s.
    (d) Will do. My hope is that somebody at ReadyNAS who is working on the updated minidlna will have some insight, based on the source filename and line number in the minidlna error message.

    Thanks again!
  • Just a quick update and a solution, in case somebody is looking for it:

    I contacted skywalker and he was able to track down the problem to the libavmedia library (from the ffmpeg project) which minidlna uses to examine media files. Turns out that this library, or at least the version that ships with Raidiator 4.2.X, barfs on mp4s with more than 20 streams. He has a patch that ameliorates the issue.
