<p>Try</p>

<pre><code>ffmpeg -i inputMovie.mkv -c copy -map 0 outputmovie.m4v
</code></pre>

<p>Depending on the subtitle format, they may not get copied over. In which case,</p>

<pre><code>ffmpeg -i inputMovie.mkv -c copy -c:s mov_text -map 0 outputmovie.m4v
</code></pre>

<p><strong>Edit</strong>: Once you have a text-based subtitle format like SRT or ASS, you can use</p>

<pre><code>ffmpeg -i inputMovie.mkv -i subtitle.srt -c copy -c:s mov_text -map 0:v -map 0:a -map 1 outputmovie.m4v
</code></pre>

Thank you for quick response, but they dont work ! In First one I become error: Could not write header for output file #0 (incorrect codec parameters : invalid argument. And for second i become:Error while opening encoder for output stream #0:3 - maybe incorrect parameters such as bit_rate, rate, width or height !!

Paste the readout of `ffprobe inputmovie.mkv` into your question.

Your subtitles are image-based and need to be converted to a text-based format like SRT. Once done, you can use the revised 2nd command. Use [Subtitle Edit](http://www.videohelp.com/software/Subtitle-Edit) to import from MKV.

that's the solution: "Edit: Once you have a text-based subtitle format like SRT or ASS, you can use": ffmpeg -i inputMovie.mkv -i subtitle.srt -c copy -c:s mov_text -map 0:v -map 0:a -map 1 outputmovie.m4v

<p>I thin <a href="http://www.videohelp.com/software/MKVtoolnix" rel="nofollow noreferrer">MKVtoolnix</a> is better and can help you get the result that you want.</p>

<p><code>MKVtoolnix</code> is a set of tools to <strong>create</strong>, <strong>alter</strong>, <strong>split</strong>, <strong>join</strong> and <strong>inspect</strong> Matroska files(mkv). Use MKVCleaver or gMKVExtractGUI to extract/demultiplex mkv video and audio files. </p>

<p><strong>Supported operating systems:</strong> Windows - Mac OS - Linux</p>

you can extract or add subtitle from/to mkv videos with it and many other things like extracting or creating chapters, extracting audio separately in a few seconds... try it and you'll see

# ffmpeg Multiple Audio Language and Soft- Subtitle

(Asked by: username_0 on 2016-01-24)

I'm trying to convert a movie, using ffmpeg, from Movie.mkv to Movie.m4v. The Movie has 2 Languages and 1 subtitle stream.
Using
ffmpeg -i inputMovie.mkv outputmovie.m4v

the result is just one audio and no soft subtitles.
What should I use to keep both languages and the subtitle (to toggle On-off on streaming box)
Thank you.

Try
ffmpeg -i inputMovie.mkv -c copy -map 0 outputmovie.m4v

Depending on the subtitle format, they may not get copied over. In which case,
ffmpeg -i inputMovie.mkv -c copy -c:s mov_text -map 0 outputmovie.m4v

Edit: Once you have a text-based subtitle format like SRT or ASS, you can use
ffmpeg -i inputMovie.mkv -i subtitle.srt -c copy -c:s mov_text -map 0:v -map 0:a -map 1 outputmovie.m4v

> **Comments:**
> **username_0**: Thank you for quick response, but they dont work ! In First one I become error: Could not write header for output file #0 (incorrect codec parameters : invalid argument. And for second i become:Error while opening encoder for output stream #0:3 - maybe incorrect parameters such as bit_rate, rate, width or height !!  
> **username_1**: Paste the readout of `ffprobe inputmovie.mkv` into your question.  
> **username_1**: Your subtitles are image-based and need to be converted to a text-based format like SRT. Once done, you can use the revised 2nd command. Use [Subtitle Edit](http://www.videohelp.com/software/Subtitle-Edit) to import from MKV.  
> **username_0**: i try it to do with 3 code (after the srt was exported - or downloaded) and i become again error message: Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument  
> **username_1**: Paste the readout of ffprobe srt into your question.  
> **username_0**: that's the solution: "Edit: Once you have a text-based subtitle format like SRT or ASS, you can use": ffmpeg -i inputMovie.mkv -i subtitle.srt -c copy -c:s mov_text -map 0:v -map 0:a -map 1 outputmovie.m4v

I thin [MKVtoolnix](http://www.videohelp.com/software/MKVtoolnix) is better and can help you get the result that you want.

`MKVtoolnix` is a set of tools to **create**, **alter**, **split**, **join** and **inspect** Matroska files(mkv). Use MKVCleaver or gMKVExtractGUI to extract/demultiplex mkv video and audio files.

**Supported operating systems:** Windows - Mac OS - Linux

**Screenshot :**

> **Comments:**
> **username_0**: hm i write i need output in m4v and this tool can just mkv output ??  
> **username_2**: you can extract or add subtitle from/to mkv videos with it and many other things like extracting or creating chapters, extracting audio separately in a few seconds... try it and you'll see
