Re: [Linphone-developers] liblinpone H264, again

[Ghislain MARY]

Hi there,

A little clarification about the H.264 license.
You can use H.264 on the Raspberry Pi without a license only if you are using the OpenMAX hardware decoder/encoder. I started writing a mediastreamer2 plugin for this some time ago but never had the time to finish it.
You can use openh264 without getting a license if you download the binary from Cisco. But Cisco does not provide a library for Raspberry Pi.
So that means that until a mediastreamer2 plugin handles the OpenMAX hardware decoder/encoder, you can not use (or at least should not use to respect the law) H.264 on the Raspberry Pi unless you get a license for it from MPEG LA.

Cheers,
Ghislain

Hi Cynthia,

It seems my information may be outdated, so now I'm not sure about what I said. I was basing that on the Raspberry Pi requiring a licensing fee for H264, and also on something I saw on the Linphone website. However, I see now that the Raspberry Pi has stated that the decode license actually does include the encode feature as well. So there is no license fee required for Raspberry Pi. (Based on this page: https://www.raspberrypi.org/blog/new-video-features/.)

And also, since you're using ophenh264.org, you may not need a license. But I'm still not sure, nor am I sure where you would get one. I would also like to know. Perhaps I can defer to someone on the list experienced with this?

Then that may not be your error, either. 

Sorry for my confusion, but let's get this sorted out. :)

Hi Leland,

Thanks for replying.

Apparently the amount of my research is not nearly enough.  :)  I thought that if I download openH264 directly from openh264.org, then I would not need to get a separete license??  If I do need a license, where would I get it?

Thanks a lot!

Cynthia

Hi Cynthia,

It just hit me: do you have a H264 license on that machine? I believe that codec requires one license per machine. That's why they encourage everyone to move to the VP8 format.

I know you've done a lot of research, but this could be easy to miss... so I just thought I'd mention it.

Best regards,

Leland...

Hello,

I managed to get open H264 loaded. SIP hand shake all seems well.  Now the error I am getting is much more cryptic to me (see below).  I am not sure what uiSliceMode is and how I can change its value.  Any ideas?

[OpenH264] this = 0x0x60000004cea0, Error:ParamValidationExt(), invalid uiSliceMode (4) settings!

[OpenH264] this = 0x0x60000004cea0, Error:WelsInitEncoderExt(), ParamValidationExt failed return 2.

[OpenH264] this = 0x0x60000004cea0, Error:CWelsH264SVCEncoder::Initialize(), WelsInitEncoderExt failed.

Thanks for any help you can offer!
