[FFmpeg-user] Concat error - No such filter '[0,0]'

[Mike Kavanagh]

Hi,

I am trying to create a single video from a set (of three) video files -
each has a single video and audio stream.

I have looked at the ffmpeg documentation and it seems a good way to do this
is via filter_complex + concat - see section 31.5 :
http://ffmpeg.org/ffmpeg.html#concat-1

Here is an ffmpeg command I am using based on the 'opening-episode-ending'
example quoted above:

ffmpeg -i HV_movieAV10000.mp4 -i HV_movieAV10001.mp4 -i HV_movieAV10002.mp4
-filter_complex '[0:0] [0:1] [1:0] [1:1] [2:0] [2:1] concat=n=3:v=1:a=1 [a]
[v] ' -map '[a]' -map '[v]' -report -y testfull.mp4

The error I get is: No such filter '[0,0]' - can anyone advise me?

Also, I am hoping this does not split up all the streams but creates a video
file the three separate AV files concatonated together (i.e. AV!-AV2-AV3)
rather than splitting them up into their six separate streams
(A1-V1-A2-V2-A3-V3)?

Using  ffprobe  shows the audio is on the zeroth stream and video is on the
first stream.

Thanks for your help advice in advance.


-Mike
