  • fftools/ffmpeg : stop injecting stream side data in packets

    fftools/ffmpeg : stop injecting stream side data in packets

    This is no longer needed as the side data is available for decoders in the
    
AVCodecContext.
    
The tests affected reflect the removal of useless CPB and Stereo 3D side
    
data in packets.

  • Merge 2 video files with their audio in a single file side by side

    21 mars 2017, par meghana

    I need to merge 2 video files along with their audio in a single file, side by side.

    I am able to merge 2 video files in single file but it’s using the audio from first video file only, whereas I need to merge the audio of the second file as well.

    Here’s how I’m trying to do it :

    ffmpeg.exe -i input1.webm -vf "[in] scale=iw/2:ih/2, pad=2*iw:ih [left]; movie=input2.webm, scale=iw/2:ih/2 [right]; [left][right] overlay=main_w/2:0 [out]" -b:v 768k ouput.webm

    I have tried various way with amerge but no success. As I am new to FFMpeg, I am not sure how can I achieve this.

    EDIT

    Below is FFMpeg Command I have used for merging both files as suggested by @occvtech, but it’s still not merging the second audio stream.

    ffmpeg.exe -i 3.mp4 -i 4.mp4 -filter_complex "[0:v] scale=iw/2:ih/2,pad=2*iw:ih[left];[1:v]scale=iw/2:ih/2[right];[left][right‌​]overlay=main_w/2:0 [out]" -map [out] -map 0:a -map 1:a -b:v 768k o5.mp4

    Below is the console output :
