The way the video was encoded is definitely an issue, but still, a crappy encoding shouldn't cause a crash...

[fritsch]

Jep - fully right. OE has no one anymore that is working on the IMX decoder ... so it is unlikely someone will fix that for you. I - for my part - have stopped writing IMX code completely. The platform is not future proof and vendor support is barely existing.

I had high hopes on version 6.0 - as the company behind these boxes wanted to fix / help whatever a lot - but nothing happened - sadly. I am not an OE developer anymore - but if I was I would vote to remove every IMX support from an upcoming release.

[azilber]

There's seriously no other dev working on IMX support? That's pretty depressing if that's that case.

[fritsch]

Nope - In OE IMX has great support by @vpeter4 - but in kodi upstream it was only taken care that it "still works" somehow. But all those that did most work for the platform itself moved on ... vendor support was / is not existent.

[vpeter4]

Actually Jon Nettleton is preparing new kernel and optimized Kodi for imx6. So there is hope for this platform.

[fritsch]

Did he say a timeline? he already prepared when I talked to him - 6 months ago?

[vpeter4]

Should be done few weeks back already. Still some small Kodi issues but from what I heard seems to be working well.
But because of splitting his time on different projects like clearfog platform this part stays behind.

[fritsch]

He should just pick everything that @mk01 has done for OSMC, including kernel (fractional refreshrates, ..) for kodi (video clock) ... and fine ... no need to reinvent the wheel again. OSMC is on 4.1.x + as xbian is ... there is no need for OE to come yet with another outdated 3.14 kernel that only works on one chip.

[fritsch]

@vpeter4 As I have you here: http://forum.kodi.tv/showthread.php?tid=248346 could you take care that this patch somehow hits OE? I get emails from users asking me about HD audio not working and this is the reason.

[vpeter4]

He doesn't do on it's own - he already work with mk01.

[vpeter4]

About the patch - I need to look it because kernel used are different. And because I don't understand this code will take time. If I succeed...

[fritsch]

The comment says what it does and it applies cleanly - I will post a build later on - which might also fix the issue in this report.

[vpeter4]

Openelec is using old kernel. And this patch doesn't apply because sample_rates in struct mxc_edid_cfg is not an array.
