Playing ffmpeg converted video on Google slides
1er avril 2019, par user1056585I have a PNG image and an MP3 audio file. I’d like to create a video with a still image and use it in a Google slides presentation. From Google’s documentation, these formats (and codecs) are supported : https://support.google.com/drive/answer/2423694?hl=en&co=GENIE.Platform=Desktop
1) FFMPEG is the easiest tool I can find to make a video from image + audio. But if you have other options, please suggest.
2) I tried a couple commands :## Command 1
ffmpeg -i image.png -i audio.mp3 -acodec mp3 -vcodec flv1 video9.flv
## Command 2
ffmpeg -i image.png -i audio.mp3 -acodec aac -vcodec mpeg4 video7.mov
## Command 3
ffmpeg -i image.png -i audio.mp3 -vcodec wmv1 final14.wmvBut all of these display the error
Video cannot be played
in Google slides. When I try to play them in Google drive, I get the errorUnable to process this video
.Any thoughts on how I can produce a video file that’ll play in Google slides ?

FFMPEG 360 mp4 to SBS for Google cardboard
3 mai 2022, par mikeI've created some 360 degree mp4 videos froma GoPro max camera.
I would like to display these on Google cardboard (side by side) in the same way as Youtube, whilst modifying the playback speed with FFMPEG.


I haven't found the right flags to convert the image to SBS with v360 or stereo3d


Any suggestions ?

Adding unique RGB color watermark per video frame with FFmpeg
8 juin 2016, par Dustin KersteinI’d like to add a unique watermark onto each unique video frame in an h264 mp4 video. More specifically, I want the watermark to be a X by X pixel square solid 8-bit RGB color, and each color watermark should be unique across all frames in the video (up to the theoretical 24 bit max of 16.7 million colors/frames).
Is this possible to do programatically using FFmpeg filters (or another tool) without requiring a photo for each possible color watermark ?
If not, assuming I already have the full set of 1029 solid color photos downloaded from http://www.solidbackgrounds.com, can anyone think of an easy way to watermark a video with <= 1029 frames using FFmpeg ?
