Unable to encode videos due to memory allocation error

  • First off I love this plugin, just wish I could get it to work. I’ve installed FFMPEG on the server and the plugin sees it, however when I attempt to run the test inside wordpress it fails with a malloc with random error messages. But what’s more when I watch the resources on the server while the test runs it appears that it doesn’t even touch the resources. I shouldn’t be seeing those malloc errors as I have 4GB (This is a VPS) with 3GB of it free.

    But when I run the test via the commandline it completes with no issues.

    From wordpress:

    It’s not really running out of memory. It seems more like it’s just not able to read the file.

    The important error messages are these:

    [h264 @ 0x13fdec0] get_buffer() failed (-12 2 (nil))
[h264 @ 0x13fdec0] decode_slice_header error
[h264 @ 0x13fdec0] no frame!

    Do you get the same error if you switch the test encode to WEBM or OGV formats?

    Thread Starter kdmitchell_toh

    (@kdmitchell_toh)

    Yes. If I switch to OGV I get;

    Webm ends up with Unknown encoder ‘libvpx’.

    Plugin Author Kyle Gilman

    (@kylegilman)

    I’m leaning towards an extra-tight security issue. When you run FFMPEG from the command line you’re running it as a user with read access to that file. When the plugin executes FFMPEG through PHP it runs it as a different user that might not have access to the file. I don’t have much ability to troubleshoot these sorts of things because I don’t know how your server is configured, but I can make a few stabs at it.

    See if it makes a difference if you run chmod 777 /home/newtheouterhaven/public_html/wp-content/plugins/video-embed-thumbnail-generator/images/sample-video-h264.mp4

    The reason you get the unknown encoder error for WEBM is that you don’t have libvpx enabled. That’s not really a problem. I don’t think it’s worth the effort to make WEBM files anymore, but I keep it around for the open source fans.

    Thread Starter kdmitchell_toh

    (@kdmitchell_toh)

    Nope, no change. I was also leaning towards permissions / security, I had to get the host (Inmotionhosting) when I started there with several items. Sadly I have access to an entire Vmware powered host and total root, but the performance isn’t there.

    Guesss I”ll go bother the webhost. Appreciate the help though.
