ReadyDLNA cannot allocate memory while scanning mkv file
ReadyDLNA on my ReadyNAS Pro 4 with RAIDiator 4.2.31 says that it cannot allocate memory when processing the metadata of three MKV files. Why would that be?
I bought more memory, upgrading the Pro 4 from 1GB to 4GB. ReadyDLNA still says it cannot allocate memory.
Here is are examples of the error message in /var/log/upnp-av.log:
[2017/08/14 14:20:26] metadata.c:686: warn: Opening /c/media/Collected/Foo/Foo.mkv failed! [Cannot allocate memory]
[2017/08/14 14:20:26] scanner.c:490: warn: Unsuccessful getting details for /c/media/Foo/Foo.mkv!

Re: ReadyDLNA cannot allocate memory while scanning mkv file
When you do a rescan, do these messages always show up on the same files? If so, did it get further when you upgraded the memory?

Re: ReadyDLNA cannot allocate memory while scanning mkv file
ReadyDLNA always complains about the same files. Judging by the error message and the source code, it's failing while reading metadata, not the video in the files. I asked about the problem here so that I won't have to read the source code to find the answer. I think the problem occurs in libavformat, for which I don't yet have the source code.
I expec that the solution is to convert the MKV file into an MP4 file with ffmpeg. Like so:
ffmpeg -i /path/to/Foo.mkv -codec copy /path/to/Foo.mp4
I found that solution at askubuntu.com

It's extracting the metadata from the files. Since it's always crashing on the same ones, it is mostly file corruption. Remuxing the MKV (which is what your ffmpeg command does) likely will solve it - though it is better remux it to another MKV. MP4 players generally are expecting AAC audio, and if your file doesn't use that you likely won't be able to play it. BTW There are other free tools you can use for this, including mkvtoolnix and avidemux.
Note if there is file corruption, there could be some issues with playback (both with the original and the remuxed files). If that's the case you'll need to re-rip it (or download it again).

Re: ReadyDLNA cannot allocate memory while scanning mkv file
I have an ReadyNAS Ultra with RAIDiator 4.2.28 and has a similar issue.
A lot of my mkv-files is not able to be added when scanned.
Also tried a manual scan through SSH, and got the:
metadata.c:686: warn: Opening /c/media/Videos/High Quality/MOVIENAME.mkv failed! [Cannot allocate memory]
I have tried to remux the mkv with MKVToolNix, tried to rename it, and a lot of different things.
It does not seem I have space or memory issue either:

Re: ReadyDLNA cannot allocate memory while scanning mkv file
Maybe move that MKV into a temporary share (that doesn't have DLNA enabled), and then scan again - moving off the files that aren't playing into their own folder. Then look for something that they have in common.

Could you advise what brand/model/reference no./part no. of memory you upgraded to please
