Philips 40pfl9904 and Mezzmo - sometimes mkv doesn't playback

**Paul** · 05-03-2011, 10:03 AM

Ok, for a modified profile please send a message to support.

To change your profile, please do the following:

1) Open up Philips7000.prf or Philips8000.prf in Notepad (they'll be located in a folder as per this thread: http://forum.conceiva.com/showthread...ofiles-located - you'll need to remove the read-only flag before editing)
2) remove or comment out the following section:

Code:

        <avcontainer id="matroska" name="mkv" encode="1" mimetype="video/x-matroska" preferredtranscoded="1" format="matroska" supportschunked="0" level="41">
                <video>
                        <format id="mpeg4" encode="0">
                        </format>
                </video>
                <video>
                        <format id="h264" encode="1" codec="libx264" preferredtranscoded="1">

                </video>
                <audio>
                        <format id="ac3" encode="1" codec="ac3" preferredtranscoded="1">
	                        <channels>2</channels>

        </avcontainer>

3) replace the first "mpeg" section with the following:

Code:

        <avcontainer id="mpeg" name="mpeg_pal" encode="1" mimetype="video/mpeg" baseline="1" dlnaprofile="MPEG_PS_PAL" format="dvd" preferredtranscoded="1">
                <video>
                        <format id="mpeg2video" encode="1" codec="mpeg2video" preferredtranscoded="1">
                                <dimensions width="1920" height="1080" />
                                <copyts>1</copyts>
                                <samequality>1</samequality>
                                <framerate>25</framerate>
                                <gop>15</gop>
                                <bitrate>9000000</bitrate>
                        </format>
                </video>
                <audio>
                        <format id="ac3" encode="1" codec="ac3" preferredtranscoded="1">
                                <channels>2</channels>
                                <channels>6</channels>
                                <bitrate>448000</bitrate>
                                <maxbitrate>448000</maxbitrate>
                                <minbitrate>64000</minbitrate>
                                <samplingrate>48000</samplingrate>
                        </format>
                </audio>
                <ffmpegadditional>-threads 4 -pix_fmt yuv420p -copyinkf -sc_threshold 1000000000 -coder ac -qmin 1 -cmp 2 -subcmp 2 -flags +loop -mbd bits -vbsf h264_mp4toannexb -fflags +genpts+ignidx+igndts -deinterlace</ffmpegadditional>
        </avcontainer>

4) save the file, restart the server (make sure you have the appropriate device profile selected for the TV in the Media Devices dialog) and try again

Please let me know how that goes.

Doesn't work this way. No effect after editing profile and restarting server

**Paul** · 05-04-2011, 09:49 AM

Can you please send in logs after that change? It should transcode to MPEG2 and play that. Also, just as a quick test, try using one of Generic profiles and see if that plays.

Finally it works.
Although some minor slows

**Paul** · 05-09-2011, 10:16 AM

I'm glad it's better. Does it work with the change or using the Generic profile?

**pzhivulin** · 05-10-2011, 11:38 PM

Dennis, could you help to tune profile according following table I've got from Philips support?

**Paul** · 05-11-2011, 09:43 AM

Yes, thank you for that info. Please send a message to support and I'll send you an updated device profile to try (mention this thread so that I could find you).
