I have a Samsung 4K TV but it can't read DTS codec so I decided to convert it to EAC3 by using FFMPEG but I want to know if there is a way to have the same bitrate and all of the settings (VBR) as the original audio on the converted one.
I use this command on the command prompt : ffmpeg -i "filename.mkv" -acodec eac3 -ab audio bitrate -map 0:a:audio number "output.eac3".
Sorry for my bad level in English.

From your posts it's hard to understand what exactly it is you want. Be more clear.
If you want 2 audio tracks: one eac3 and one the original DTS, try:
ffmpeg -i "filename.mkv" -map 0:v -map 0:a -map 0:a -map 0:s? -c:v copy -c:a:0 eac3 -ab:a:0 640k -c:a:1 copy -c:s copy "output_filename.mkv"
ffmpeg -i "filename.mkv" -map 0:v -map 0:a -map 0:s? -c:v copy -c:a eac3 -ab:a 640k -c:s copy "output_filename.mkv"
(Is ffmpeg's eac3 encoder even better quality than its ac3 encoder? If not you can use "ac3" instead of "eac3" for even more compatibility.)
Thanks for your answer.
Well sorry I wasn't clear on my question what I want it's only to extract an audio (DTS-HDMA) of an mkv and convert it to EAC3 by keeping the origianl audio settings (the channel, the channel layout and keeping the bitrate ...).
But lately I have a problem to convert DTS-HDMA 7.1 to EAC3 7.1,ffmpeg downmix to EAC3 5.1.

yes .. ac3 only supports 5.1 and 640 kbs ... (that's just an example)
if you want eac3 'high bitrates' and 7.1 .. you need encoders of payment責任者
could be this .. surely there are others
