mp4 H264 transcoding...

Hi all,

I landed yesterday to this great product and I think that my quest for an all around DLNA server has come to an end. The fact that you can provide profile per renderer is THE ulimate feature. Well done Now to my question... My Samsung B series seems to be detected and propertly handled by serviio. Howeve there is a group of video files that are giving me "unsupported codec" on screen. Doing ffmpeg -i on the file name I take:

Metadata:

creation_time : 2012-12-21 00:49:42

I guess I need some kind of transcoding to add to my samsung B profile. Any help will be greatly appreciated.

Kind Regards
Yiannis

Seems good...only 720x304 resolution not sure it is standard.

It would be quite intereting if you could point out an alteration to the profile so that I can force, even for a test, some kind of transcoding for this case. Not as permanent fix, since I realise that the problem is not obvious. at least as an exprimentation. If the reolution is "strange", could we bring it to something more acceptable?

EDIT: The particular files are not playable on B series Samsungs. On my C series and on my BD plays fine...

Thank you in advance
Yiannis

I have the same problem on my Samsung B series. I don't know if i can say it but its movies from YIFY.

If somebody had some solution please let me know.

thank you

@skorp_jon: these files use a high level of compression and low bit rate to achieve the small file size and might not be supported by your device, so the video will need to be transcoded. You can do this by adding something along the lines of:

  Code:

<Video targetContainer="mpegts" targetVCodec="mpeg2video" DAR="16:9" targetACodec="ac3" aBitrate="384">
   <Matches container="mp4" vCodec="h264" profile="high" />
</Video>

to your profile. The files I have seen are High@L4.0 and above, so you can also include levelGreaterThan="3.2" in the matches command; and if you need to support MKV, change the "MP4" to "*".

I had the same problem, and your code worked. (well I had to change "MP4" to "mp4").
Thanks!!!
