I had an impression that h.264 Baseline/5.0 files would play on Rpi but they do not work. I'm using OpenElec nightly builds and they will not play.

Is there a reason they do not work? Bandwidth or something else?

Hi popcornmix.

I'm not unfortunately at my computer right now, but I've found someone posting media info which is from 550D.
Here it is:

Code:
Overall bit rate                 : 47.0 Mbps

Ouch. I'm guessing it doesn't do much compression (rather than being higher quality than Blu-Ray).
Can't see a specific reason for that not playing. A sample would be useful.

I know popcornmix has a greater knowledge of rpi than me, but I was under the impression that its hardware decoding doesn't do level 5, only up to 4.1.

Eg http://www.raspberrypi.org/phpBB3/viewto...f=2&t=4668

Can you please post a short clip somewhere if you can? I will do it in a few days when I get back home otherwise.

I don't know if this helps but my old WDTV Live with Sigma Designs SMP8655 SOC plays the same files directly out of the camera.

The hardware was designed for 4.1 (Blu-Ray). Originally the video driver had a fixed memory allocation for each of the supported profiles/levels.
If the level was above 4.1, or if it was a 4.1 stream that reported 3.1 then it would just report an error.

Many months ago we moved to a newer driver (vdec3) which does all memory allocation dynamically, and doesn't reject higher profiles.
As long as resolution is no more than 1920x1080 and GPU memory isn't exhausted, then I'd expect higher level streams to play.

The file played perfect for me. Can you try a build that includes the latest firmware. E.g.
http://forum.xbmc.org/showthread.php?tid...pid1596575

If still a problem then post a debug log.

This is weird.
I just tried the same videos that were not playing and they all played perfectly.
I was on build RPi.arm-devel-20131215184433-r16572-gb5a38fc

Than I updated to the latest build RPi.arm-devel-20140110215319-r16936-gd4c9cbe, tried the videos again and they refused to play (only audio played).
I'm sending you the link to the .log I just grabbed from the log folder.

You can search for the MVI_1817.MOV file for example. Once it played, once it didn't with the error like this:
Code:
13:32:07 127.312408 T:2981098576   ERROR: COMXCoreComponent::DecoderEventHandler OMX.broadcom.video_decode - OMX_ErrorStreamCorrupt, Bitstream corrupt
13:32:07 127.312843 T:2762994768   ERROR: OMXPlayerVideo : Error open video output
13:32:07 127.364250 T:2762994768 WARNING: OpenVideoStream - Unsupported stream 0. Stream disabled.

I tried one more time with the build from 14th and I have the same problem. I tried restarting XBMC from SSH and then to play the files and they played well. Once one file is playing, every subsequent file plays well.

@popcornmix could you find what was the issue? Can I do something more to help debugging?

RPi can definitely play the videos that's what's important.

So far I've not seen it fail to play.
What makes it play/not play?
E.g. from a clean boot does it play? Does playing a different file make it play/not play?
