Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Media Framework Support on OsX Is Very Limited

HI,

I am using UE4 with OsX, and I cannot find any video file format working reliably with the Media Framework. Under OsX obviously you cannot import WMV videos, and mp4/m4v video using H264/MPEG encoders will play once, will not not support seek (and so cannot be rewind), some encoders (Sorenson, for example) will crash and so on.

Is there any plan to add some more support to OsX version of Media Framework anytime soon, or is it better if I make my mind and switch to Windows? Playing videos reliably is a key feature for a project I am going to develop. I know, is more a feature request than a bug report, but I believe that video textures should get some more attention... :)

Thank you very much for your impressive work! Later, Bab

Hi. No seeking is working whatsoever under OSX still in 4.7 preview 8. PLEASE PLEASE PLEASE check your commits!

Ciao e grazie, Bab

Hi Bab, I'll look into why this isnt working at some point in the next few days.

And, under Windows, I have seeking but no audio... I am checking with both C:\Program Files\Unreal Engine\4.7\Engine\Build\IOS\Resources\Movies\Default_Startup.mp4 and the infamous sample Windows movie wildlife.wmv. Ciao :)

Hi! In 4.7 final release I can confirm support for seeking on MP4 and WMV files under Windows (not under OsX, but I will survive), but I cannot hear any sound when playing the video from the UE4 Media Player and/or when I apply the media texture/material anywhere in the scene, even if the correct audio track is selected. Is it supposed to work so? Or I have to explicitly import the audio track and manage it separately? Is it a question of audio format support in the video? If so, could you advice a working audio format to use in MP4/M4V/WMV files? Thanks for your support and excellent work, Bab.

Been having this issue on OS X as well. in 4.7.2 My .MP4 files wont allow for me to seek or even restart/loop a movie as a texture. Not sure what I am doing wrong. Thanks.

avatar image Babele Dunnit Mar 11 '15 at 09:06 AM

You are doing nothing wrong, Backdrifter. The same stuff under Windows will expose seeking/restart capabilities, BUT the audio will not work. I tested it extensively. It seems Epic is just giving a not-so-high priority to the Media Framework... which is strange to me, they introduced this stuff back in 4.5. And I believe this is VERY important for a whole new class of products (i.e., in-world 360° movie players, which could be a whole new product used in conjunction with Oculus and that VR stuff). As of 4.7.2, the Media Framework is simply useless. (yes, you can workaround it in Windows, extracting the audio tracks from your videos, starting them explicitly etc... bleah. ) :(

Thanks Bab. I hope they address it soon. I have been trying to figure out how to replicate an old movie theater and would love to be able to have the ability to play movies back and use for Oculus, etc. Thats been my primary goal. Hope they can get around to it soon. I know these things can take time.

Hey Bab,

We added seeking for osx and that should be in the next major release, 4.7. We'll try and repro the crashes you mention and address them asap, as for supporting further movie file formats, Ill see if I can take a look at that for a future release.

We should get round to giving the media framework a bit more attention in a future release. :-)

Good! Is it in 4.7 preview 2 already? Thank you very much!

avatar image Terence.Burns Jan 13 '15 at 10:30 AM

Seeking should be :-)

4.7.6 with OSX 10.10.3 Mac Pro (Late 2013) AMD FirePro D700 - The issue with MP4 only playing once and not being able to seek is still present. It works fine on Windows with AVI files. Please show the Media Framework some love on OSX. I'm trying to do some video texture compositing for a VR project and am blocked with this issue.

avatar image Babele Dunnit Apr 29 '15 at 09:25 AM

Holy Cow, VMC, I began to think I was alone in the dark! I would have say this should be a major issue for a lot of users out there, but it seems not... Same exact motivation, I must do some Oculus + 360video stuff and I am blocked.

BUT: when you say " It works fine on Windows with AVI files" do you mean also the audio part? I am unable to get audio working on Windows, tried many AVI formats etc. (obviously, audio alone works perfectly.)

In case, would you please share some details about what kind of formats/codecs etc are you using in your AVI files?

thanks a lot, Babs

Just an update, We have had a qa pass on what functionality may be missing and we hope to address these for 4.9.

Is there any specific information on what fixes/improvements were made with 4.9 to address issues with Media Framework on OSX?

You can find fixes and feature implementations in our Release Notes section within our Documentation below.
