I need to change from full hd to 720x406 in transcoding.

[Comancheace]

But in my pc it continues to transcode to mpeg2 and not to m2ts. The file name is this:

8-mpeg_ntsc-mpeg2video-ac3.mzt. Wich i think means that was transcoded with mpeg2video with ac3 sound. Can´t you put more transcoding options in the software? Or there is another way to change the ffmpeg settings?

Thank you

[Comancheace]

Í tried everything but nothing. I needed more options in the transcoder. This is my last try. Can somebody help me?

Thank you.

Where can i change the ffmpeg options for transcoding?

In the device profile file (*.prf) - and remember to restart the server after you make modifications for the changes to take effect. Also, if you keep a backup of the original profile, but don't change the extension, then it may be picked up and used instead of your modified file - so that's one more thing to check if your changes do not seem to have any effect.

Can you please post the compelte device profile as you have it now (after your modifications) here or send it to support (at) conceiva (dot) com and I'll help you out.

[Comancheace]

Thank you. When i arrive home i´ll sen it to you. Yes i have a backup file of the profile but i changed the name. But i´ll try to change it another directory.

Thank you

[Comancheace]

Here are the profiles that im using. One thing works: the files in the blu-ray don´t appear as mpeg anymore but now they appear at m2ts. The only problem is that it doesn´t start the transcoding. Neither ffmpeg.exe or x264.exe appear in the task manager. Pictures play well but music doesn´t work too. What i am doing wrong? Changed the backuped profiles to another directory. Here are my profiles:

SonyBraviaKDL..prf

NetgearDigitalEntertainerLive..prf

Thank you!

Thanks for the device profiles - can you please also make a log file of trying to play one of the videos that needs transcoding, but with transcoding not starting issue and send it to support (at) conceiva (dot) com, so that I could take a look at why it's failing?

One immediate thing that I notice is that the codec for h264 encoding should be libx264 like so:

<format id="h264" encode="1" codec="libx264" preferredtranscoded="1">

Also, change the ac3 audio section in mpegts to be like:

                        <format id="ac3" encode="1" codec="ac3">
                                <channels>2</channels>
                                <channels>6</channels>
                                <bitrate>448000</bitrate>
                                <maxbitrate>448000</maxbitrate>
                                <minbitrate>64000</minbitrate>
                                <samplingrate>48000</samplingrate>
                        </format>

If transcoding still doesn't start with the above change, please send in the logs.

Tried that modification but still doesn´t transcode. But i think the problem is the bitrate, fps, etc settings. See my log:

Can you tell me the paramaters to put?

Thanks

[Comancheace]

Can´t play m2ts files neither. What option do i put in the profile to be able to read m2ts files?

Thanks

[Comancheace]

Hi Dennis. Can you help me on this?

I need the bitrate settings for the m2ts

Thank you

[Comancheace]

I putted this bellow de m2ts settings:

<copyts>1</copyts>
<samequality>1</samequality>
<framerate>29.97</framerate>
<gop>18</gop>
<!--
<bitrate>11000000</bitrate>
<maxbitrate>9000000</maxbitrate>
<minbitrate>0</minbitrate>
<bufsize>1835008</bufsize>
<muxrate>10080000</muxrate>
<packetsize>2048</packetsize>

And it worked! just one more thing... Now it transcodes also original m2ts files too... How can i change that? How can i say to the software that that file, doesn´t need transcoding?

Cheers

Dennis, apreciated if you could give a help

Thank you
