    Hi,

    I am attempting to convert a m2ts file into a mkv using ffmpeg. I run ffmpeg with the following options.

    Code:
    ffmpeg -i 00002.m2ts \
           -vcodec libx264 \
           -vpre slower \
           -s hd1080 \
           -aspect 16:9 \
           -acodec ac3 \
           -f matroska \
           -map 0:0 \
           -map 0:1 \
           ~/test1.mkv
    However I get the following when running.
    Code:

    Number of stream maps must match number of output stream
    I don't understand what I have done wrong with mapping the streams I want from the source to the output. Thanks in advance for any help.

    If you try another audio stream do you get same error?
