Is there something in the Chime API for JS that facilitates replaying a meeting including all content shares or stitching everything into one file?

Question

Hi,

I'm using Amazon Chime SDK for JS and have created everything needed to facilitate meetings, including the pipelines to capture and concatenate the media.

I can see the webcams and audio stitched together under the /audio folder in the concat bucket, which is perfect. However, the content shares (screen shares) end up in the /videos folder under a few different files (I guess it's one per screen share) so I'm left with multiple .mp4 files.

My question is - is there something in the API that facilitates the replay of a meeting recording, which chronologically plays all the video files together?

During the meeting, record both the webcam/audio streams and the content shares (screen shares) and save the content shares as separate video files (e.g., share1.mp4, share2.mp4, etc.).

After the meeting, use a server-side process (outside the Chime SDK) to concatenate the individual content share video files into a single video.

Merge the files chronologically. 
`ffmpeg -i share1.mp4 -i share2.mp4 -filter_complex "[0:v][1:v]concat=n=2:v=1:a=0[outv]" -map "[outv]" stitched_shares.mp4`

This command concatenates share1.mp4 and share2.mp4 into stitched_shares.mp4.

Lastly, provide the stitched_shares.mp4 file to users for playback.
