[QUOTE="forczekattila, post: 20612, member: 3965"] Let me give an update, maybe someone is interested: - Auto sync cached video (which includes the audio) with Android app called FolderSync, which can be set up to be scheduled, and triggered by my home WiFi, and phone being plugged to the charger. So it can move files to the shared folder on my NAS. - On the desktop (Win 10), I can do the same with SyncToy, when plugging in the SD card of DonGo (name of my Spark) for moving the hi-res videos. - On the NAS I can run batch for merging the audio and the video. Here is a sample line of code: ffmpeg -i DJI_0040.MP4 -itsoffset 1.0 -i 2017_11_22_19_36_35.mp4 -c:v copy -c:a aac -strict experimental DJI_0040_Audio.MP4 Challenges I am still facing: - The audio and the video is not in sync from the starting of the file, and the delay is not consistent. (In the above example it is 1 sec) - Matching the two video files from a batch is not easy. Usually the timestamp of the files match, but not always. There is an info file besides the cache video giving the file ID, but need more coding to fit this logic into the ffmpeg script. Hope this may give some ideas, and feel free to add yours. [/QUOTE]
