Need to transcode, but all I get is muxing

I need to transcode as my TV spontaneously reboots during playback (too high bitrate will do that I think) if this video, but I can't seem to create a filter that will perform transcoding on this video.

From the serviio log file (debug), I captured this command:

2017-04-20 15:54:33,289 DEBUG [ProcessExecutor] Starting C:\Tools\FFMPEGWrapper\ffmpegwrap.bat -fflags +genpts -threads 4 -i V:\SomeVideo.mkv -y -threads 4 -c:v copy -bsf:v h264_mp4toannexb -c:a:0 copy -map 0:0 -map 0:1 -sn -f mpegts I:\TEMP\Serviio\transcoding-temp-9e24dbd2af0e0ec5e02ed5df496ff2cd.stf

ffmpegwrapp.bat passes the options unmodified on to ffmpeg.exe in this case (verified).

It looks to me as it is just copying the video stream. There is sound, even though my TV doesn't know about EAC3 but there is audio. I guess the TV somehow knows about EAC3, but it is from 2010 so I dont see how. The transcoded file still uses EAC3 (which ffmpeg arguments ask for (copy)). The transcoded video stream is MPEG-TS with video as AVC and audio as EAC3. Bitrate is 17.6Mbps and this is what is killing my TV.

I have shown my profile and the source video information below. What kind of profile (or matches) do I need to make to ensure video transcoding (and optionally, audio transcoding)? Please. :)

The video is this:

This is the profile I have specified. It is kind of messy right now as I can't figure out why it wont recode the video.

Re: Need to transcode, but all I get is muxing

The only piece of your profile that would capture that particular video is this one:
  Code:
<Video targetContainer="mpegts" targetVCodec="mpeg2video" maxVBitrate="15000" targetACodec="ac3" aBitrate="384" DAR="16:9" forceInheritance="true">
<Matches container="*" vCodec="h264" profile="high_10" />
<Matches container="*" vCodec="h264" profile="high_422" />
<Matches container="*" vCodec="h264" profile="high_444" />
<Matches container="*" vCodec="h264" profile="high" levelGreaterThan="4.1" />
<Matches container="*" vCodec="h264" profile="main" levelGreaterThan="4.1" />
</Video>


<Matches container="*" vCodec="h264" profile="high" levelGreaterThan="4.1" />

Every other line states a container that doesn't match yours (MKV). But, your format profile is High@L4.1, which the highlighted line above is causing it to be excluded from the profile section. If you want to transcode this file, change the levelGreaterThan to "4.0". Alternately, just remove the profile portion of the line and you will transcode every H.264 video.
