Samsung C/D Series On-line Transcoding Profile

[Former user]

This request is to update the Samsung C/D series profile to correctly support Online Transcoding.

The existing 1.6 profile should have the following added to it. The video addition is explained in ticket #425 change #10 https://bitbucket.org/xnejp03/serviio/issue/425/samsung-d-series-tv-will-not-play-online The audio addition is just a generic profile carry over and may not be required.

{{{ #!python

<OnlineTranscoding> <Video targetContainer="mpegts" targetACodec="ac3" aBitrate="384"> <Matches container="mp4"/> </Video> <Audio targetContainer="mp3"> <Matches container="flv"/> </Audio> </OnlineTranscoding> }}}

Note that the video addition for mp4 is only required to override the B profile online transcoding rule which will otherwise convert mp4 files to mpeg2.ts. I really question why this B rule exists since no such conversion is specified for local .mp4 files unless their avc level > 4.1 and then the conversion is to mpeg.ts which implies that the B series is capable of playing the ts muxed .mp4 files defined in the generic profile. If the B rule is removed then no Online Transcoding section is required in the C/D profile since the inherited generic profile will suffice.

Here is a further revision to address online nasa feeds. See http://forum.serviio.org/viewtopic.php?f=23&t=3729&p=24969#p24969

[Petr Nejedly]

fixed as a part of #425, haven't added the last addition for now.

[Former user]

This last addition remains a bug in beta 2 per the following:

I have an rss that atom that specifies a media:content .mp4 url.

FFMPEG reports that link as an mpeg-4/aac.mp4 file. #1 below

Downloading with FFMPEG however yields an AVC/AAC.mp4 file according to mediainfo, #2 below

With beta 1 it transcodes correctly to mpeg2video/ac3 due to the online transcoding rule for .mp4 inherited from profile 2 and plays correctly. see mediainfo for transcoded file #3 below

With beta 2 it just copies the video per the profile 1 .mp4 rule (as mpeg-4 which it really is not) and encodes the audio to ac3 and fails on "Video data not suported" see transcoded file ffmpeg #4 & mediainfo #5 below.

So 2 bugs I guess. 1. Mal detect of avc stream as mpeg4 by FFMPEG and erroneous transcode of that file by FFMPEG.

2. Need for mpeg-4 transcode rule as previously reported to transcode to mpeg2video
