OpenELEC Testbuilds for RaspberryPi Part 2
(2013-10-30, 19:37)doveman2 Wrote: In addition he has some files which MediaInfo identifies as Mpeg-4 (Microsoft) which also only play the audio on the RPi.

Is there any way to play these and the S-Mpeg 4 files on the RPi? He says he's got quite a lot of files burnt to disc and it's going to be a major chore if he has to convert them all to another format for the RPi to be able to play them. I don't even know how he'd go about this without worsening the quality either.

The Pi will play MPEG-4 compliant video. From http://en.wikipedia.org/wiki/Windows_Media_Video:
Quote:Microsoft MPEG-4 version 1 MPG4 Video for Windows-based codec. Non-standard MPEG-4 codec incompatible with the later standardized version of MPEG-4 Part 2.
Microsoft MPEG-4 version 2 MP42 VfW-based codec. Non-compliant with finalized MPEG-4 part 2 standard.
Microsoft MPEG-4 version 3 MP43 VfW-based codec. Non-compliant with finalized MPEG-4 part 2 standard. Eventually locked for encoding only with ASF files (build 3688 and earlier could also encode to AVI).

so, no, these are not MPEG-4 compliant and can't be played on the Pi.
handbrake is quite simple to use to convert them.

In future make sure videos are encoded with open standards (H.264 is the obvious choice now) not proprietry variations.

This window stay 8 seconds, shuts and immediatly reappears for 8 seconds then shuts.
If I move the mouse from any place to the "Video" button (without click) the window appears again with the same behaviour.

This is known about:

There is a (just one) report that it was fixed a couple of weeks back, but maybe not...

could fix it, and I'm just doing a build to test it.

A top of tree rebuild has started and exited a few times without the usual segfault, so this fix looks promising.

Oh, if only life were that simple!. My brother gets a lot of clips from downloads or sent to him I guess, so he's not responsible for and can't control how they're encoded. With his old PC, he had that hooked up to the TV and could play all these clips fine but now with his RPi he can't play half of them, so it doesn't seem like progress to him and it does seem rather sucky that the RPI can't play them. Is this because they use a proprietary codec that isn't available for the RPi or is there some fundamental technical hardware reason they can't be decoded or could in theory a codec be available in future that would decode them on the RPi?

I guess he'll just have to convert them for now but is there any way to transcode them to be compliant without degrading the quality further or will they have to be fully converted. I'm not sure if Handbrake is simple enough for my brother and it seems he'd have to specify a Destination file for each one, which will be a bit tedious if he's got a lot to convert, so something that will just let him add files and automatically create the output files in the same folder with an added suffix will probably be a lot quicker for him, if there's something like that.
Updated Frodo Branch

Thanks for the new build

HAPPY HALLOWEEN EVERYONE

I rebuilt the SD from scratch and changed start.elf and fixup.dat from:
https://github.com/Hexxeh/rpi-firmware/tree/next

Music is still jerky.

Bug is fixed


However I'd like to add what I saw but can't repeat again:
- I rebuilt from scratch because I had no audio at all and could not find out why. Now it's good.
- In System >Settings >System > Input perif > CEC, I saw 2 lines I can't see now. One with something like "On what is attached the RPi <TV or AVR>. One with something like "HDMI port number" and a cursor to move from 1 to ?"
Where are these option now?

The Pi decodes video with a hardware block designed to support common standards.
There is no way it can decode proprietry formats it wasn't designed for.

In System >Settings >System > Input perif > CEC I have "HDMI port number" with a slider from 1 to 15 (second option down).
As the Pi only has 1 HDMI port, I'm not sure how that will be useful.

I use a script to convert videos to ipad format. See:
http://pastebin.com/cP0SVAjD

If you create a shortcut to this script (call it convert.bat) in the "send to" folder (http://www.howtogeek.com/howto/windows-v...d-to-menu/)
you can select a number of video files in a directory and select convert, and they will be batch converted.

But why I saw that but I can't see it now? Bug?
Edit: Just for information as the last rebuild seems to be good

OK, thanks for the info. I think I might be able to use Plex Server running on the PC to transcode the files to H.264 on the fly, so that the RPi can play them, which will be less effort than converting them all.
Test OpenELEC-RPi.arm-Rbej-Version-Frodo-Branch(31.10.2013)

same issue than OE version Gotham devel-20131025192011-r1693

The file plays well for me. There is a new update here:
https://github.com/Hexxeh/rpi-firmware/tree/next
which could affect hdmi audio and may be worth trying.
This is a firmware update, I am not sure how to do it. I don't see all the files.

how-to2

Could you tell me what files I have to copy and where?
