Hi,

i'm converting MCE recordings to watch them on my Samsung TV (stream). For this the Framerate has to be 25 Frames/s, sometimes I got 42 Frames/s.
Not sure where to adjust/configure this. MCE / MCE Buddy / DVB-S Reciver.

I appreciate any help.

You can adjust the settings in profile.conf depending upon which profile you're using (mencoder or ffmpeg). You'll need to study the ffmpeg commands.

E.g. use the -r command for ffmpeg, so in the profiles.conf for teh ffmpeg video line for the respective profile include the -r 25 (set rate to 25 frames/sec) in the parameters.

Study FFMPEG Documentation for more details.

I've been trying to use the ffmpeg -r option in the profiles.conf file but it never seems to change anything. I'm specifically using the latest 64 bit 2.1 Release 2. I've tried adding the parameter to the beginning and end of both the ffmpeg-video and ffmpeg-general lines. I was assuming it applied to ffmpeg-video but when it didn't work I went with the other. Examples:

ffmpeg-general=-r 30 -async 1 -threads 0

ffmpeg-video=-r 30 -ss 3 -vf yadif=0:-1,hqdn3d -vcodec libx264 -b 2000k -flags +loop -cmp +chroma -deblockalpha -1 -deblockbeta -1 -bt 256k -refs 8 -bf 3 -b_strategy 2 -coder 1 -me_method hex -me_range 16 -subq 8 -partitions +parti4x4+parti8x8+partp8x8+partb8x8 -flags2 +wpred+mixed_refs+dct8x8 -g 25 -keyint_min 20 -level 41 -trellis 2 -sc_threshold 40 -i_qfactor 0.71


The video input is at 60 fps and the output stays at 60 fps for me for some reason. I've also had the same problem with the -vol parameter not working for me.

@komputerguy

What I had suggested was actually just a template for FFMPEG. It depends up on what profile you're using. E.g. if you using MP4 profile then the mencoder video needs to be changed, if you're using divx then the ffmpeg, for m4v it's handbrake etc.

What profile are you using?

Also ergarding the Samsung TV. I too have a samsung tv at home and I'm able to stream all the video's converted with the "MP4 High Quality" profile without any issues. Are you sure about the framerate?

If you can upload the video to my ftp server below I'll try to it out and see what's going on.

I've tried it using the "MP4 Normal" profile. I'm not sure if you were talking to me about uploading the file, but I'm going ahead and uploading it to your server.

I saw your profile that you had uploaded, please note a few things:

[MP4 Kevin]
Description=Test
order=ffmpeg
ffmpeg-general=-vol 416 -ss 3 -threads 0 -vf yadif=0:-1,hqdn3d
ffmpeg-video=-vcodec libx264 -b 2000k -flags +loop -cmp +chroma -deblockalpha -1 -deblockbeta -1 -bt 256k -refs 8 -bf 3 -b_strategy 2 -coder 1 -me_method hex -me_range 16 -subq 8 -partitions +parti4x4+parti8x8+partp8x8+partb8x8 -flags2 +wpred+mixed_refs+dct8x8 -g 25 -keyint_min 20 -level 41 -trellis 2 -sc_threshold 40 -i_qfactor 0.71
ffmpeg-audio=-vol 416 -acodec libfaac -ab 160k
ffmpeg-audioac3=-vol 416 -acodec libfaac -ab 160k
ffmpeg-ext=.mp4

OKAY, before I explain, please note the commands/parameters are generated in the following manner:

WAY TO BUILD THE COMMAND LINE
GeneralParameters + InputFile + VideoOptions + AudioOptions + OutputFile

Given the above, please see my comments below
1. the -ss 3 should come in the video command and not the general commands since -ss should take effect AFTER the input file to take proper effect (the purpose to -ss is to decode and discard video (corrupted video), if it comes before the input file, FFMPEg only discards without decoding, which does not fix the problem)
2. Audio: as of 2.1.2, FFMPEg has been upgraded to the 2/15/12 version. This version does NOT support libfaac (deprecated) instead it has support for libvo_aacenc (much better quality). See the available templates for FFMPEG below (starting 2.1.2)
ffmpeg-audio=-acodec libvo_aacenc -ab 160k -ac 2
ffmpeg-audio=-acodec ac3 -ab 192k
ffmpeg-audio=-acodec copy
3. -vol 416 should come in the audio section and not general parameters, it may confuse ffmpeg leading to more issues
4. Under some conditions and Comskip Enabled FFMPEg may fail in 2.1.2, this will be fixed in 2.1.3

That was not the profile I was using, it was just me messing around but I appreciate the comments. The profile I had change for framerate and was using was the "MP4 Normal"

The reason I had the vol parameter in the general section of that other profile is that I did initially try it in the audio section with no effect. It was a change I was trying out of desperation.

Thanks
