If so how ?

Kind Regards

Thanks i tried that tool earlier , and i keep getting codes not supported on by samsung c-series TV. I need to transcode them again with media coder for them to work.

Any ideas? If i transcode them directly with media coder that does not work either, appears to be a suttle change required for the transcoding to work

sorry silly question whats bitbucket

Yeah this would be useful. I have a few videos taken from a friend's Blackberry handset (not sure which one) which are as follows:

There seem to be a couple of obstacles here. Though many renderers will play the audio and video codecs contained within the 3gp container, most of them will not natively support 3gp itself - so these files will need remuxing at the very least. The first problem is that it doesn't look like MPEG-4 Part 2 video can be remuxed into an mpegts container. I just get a corrupt file that nothing (not even VLC) can play.

If I remux to an mp4 container it works, though of course the problem is that we can't do that on the fly once Serviio supports 3gp because mp4 is not a live-streamable container:

Code:: "C:\Program Files\Serviio\lib\ffmpeg.exe" -i "G:\video\Trailers and samples\VID 00005-20110303-1555.3GP" -vcodec copy -acodec copy c:\temp\test.mp4

I then notice that the Sony Bluray Disc Player doesn't like either the audio bit rate or sample rate (it plays silently), so we need to transcode it. We have no aac encoder in FFmpeg by default (libfaac is non-GPL), however the mp4 container does support mp3 audio and the following command yields a file playable on a Sony BDP. The -ar 44100 fixes the silent audio track - presumably libmp3lame also doesn't like 16KHz as a sample rate:

Code:: "C:\Program Files\Serviio\lib\ffmpeg.exe" -i "G:\video\Trailers and samples\VID 00005-20110303-1555.3GP" -vcodec copy -acodec libmp3lame -ar 44100 c:\temp\test.mp4

Looking at this container format comparison, it looks like MPEG-4 Part 2 video is supported in MPEG-2 transport stream (.ts) but not in BDAV spec MPEG-2 transport streams (.m2ts). Unfortunately FFmpeg doesn't seem to make the distinction and only offers the latter as far as I can tell. I can't test with TSMuxer which does offer both containers, because it understands neither .3gp nor MPEG-4 Part 2. So no remuxing on the fly unless someone else figures something out.

I tried the ffmpeg commands
"C:\Program Files\Serviio\lib\ffmpeg.exe" -i "G:\video\Trailers and samples\VID 00005-20110303-1555.3GP" -vcodec copy -acodec libmp3lame -ar 44100 c:\temp\test.mp4
The plan was to transcode all the files via an automated process which is launched when ever additional 3gp files are downloaded and then transcode them to a different location so Serviio culd then stream them to the TV
The commend only worked for the smallest file, for all other files i got video codecs not supported (on the TV)
Do you know the optimum setting for a samsung c-series tV 46C750
The only codecs i could get to work with any relability was the mpeg 2 codecs for the conversions and even these failed some time.....

Can you post the result of FFmpeg -i on an example Nokia 3gp file?

you could try forcing the bitrate with -ab 64k

Posted: **Sun Mar 20, 2011 2:27 pm**

I'll try it but the below worked well

"C:\Program Files\Serviio\lib\ffmpeg.exe" -i "c:video0193.3gp" -f vcd -target pal-vcd -mbd rd -trellis -mv0 -cmp 0 -subcmp 2 "c:Video.mpg"

FFmpeg -i for a 3pg from android HTC phone. The video is mp4 so I presume that could be output via serviio ? audio is "amrnb" which is new to me

According to this (http://en.wikipedia.org/wiki/3gp) 3gp is indeed just a (slightly modified) MP4 container. The audio codec is unknown to Serviio so the file would not be added to the library. I'll look what can be done.

I've been playing around with Wild Media as part of trying to get AVI working on my Sony 2011 model. Anyway, I noticed its transcoding 3gp files to MPEG2. Not a killer feature for me but would be neat and I'm not switching from Serviio

There is already a ticket open for this to be added to serviio and has been assigned to be added to version (0.6)
