    Hi,

    I am using FFMPEG in my project for compiling one or more videos.

    My problem is this
    I am having two videos in which one video having audio stream and video stream both and in other video i am having only video stream but no audio stream.

    When I am compiling these two videos I am getting error

    Stream specifier ‘:a’ in filtergraph description [0:v] scale=320:240, pad=340:ih:(ow-iw)/2:0, setsar=1/1, setpts=PTS-STARTPTS[v0]; [1:v] scale=320:240, pad=340:ih:(ow-iw)/2:0, setsar=1/1, setpts=PTS-STARTPTS[v1]; [v0][0:a][v1][1:a] concat=n=2:v=1:a=1[v][a] matches no streams.

    How can I solve this..??

    Regards
    Ankit

    You’ll of course need to provide the complete console output from your command; otherwise we can only make guesses.

    Please format it properly with the CODE button.
