Problems with switching between HD and SD channels via IPTV

[deseyve.lukas@…]

Hi,

i use mythtv for watching TV via IPTV. All works fine, SD and HD channels, but...

if i watching some HD channel and then i switch to some SD channel, so watching this SD channel dont work. I must restart my mythbackend and then is all again fine.

I use VDPAU, and in mythbackend log i see these error messages

[h264 @ 0x337724a5c0]mmco: unref short failure [h264 @ 0x337724a5c0]number of reference frames exceeds max (probably corrupt input), discarding one

but if i turn off vdpau (i will use some another playback profile), so i have the same problem with same error messages

In VLC (without VDPAU) i dont have this problem.

Please can you help me?

mythbackend.log with verbose -all

VDPAU is irrelevant to any errors you may get during recording. Please upload a copy of your backend logs. The existing file is just 10KB of spaces.

I think that i know where is the problem... but i dont know how it resolve. Because all HD channels have adress udp://... and all SD channels have address rtp://.

For exmaple: #EXTINF:0,1 - ČT1 rtp://@239.255.11.107:1234 ... #EXTINF:0,16 - ČT HD udp://@239.255.11.84:1234

And mythtv dont know switch without rtp and udp stream. But i can't change address in my m3u from udp to rtp (or conversely).

I attach whole my m3u file.
