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 playedin 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 ?

avi encoded to streaming mp4 or webmnot playing in html5 player
30 mai 2013, par Vprnl[EDIT]
I'm trying to get ffmpeg to encode various AVI files to mp4 for streaming purposes
I use this nodejs to start FFMPEG.
When I try this (webm) (some settings are wrapped by the node module but produce the default FFMPEG command) with this command :
.withVideoCodec('libvpx')
.addOptions(['-bf 8','-bt 240k','-preset fast','-strict -2','-b:v 320K','-bufsize 62000', '-maxrate 620k','-movflags +empty_moov','-y'])
.withAudioBitrate('192k')
.withAudioCodec('libvorbis')
.toFormat('webm')The video get's streamed properly to the client but the duration isn't passed on. So the video has a duration of 'infinite'.
So I tried to encode with H264. Which also works (I see the duration being set in the client) but no picture sadly.
For H264 I use :
.addOptions(['-y','-vcodec libx264','-bf 8','-bt 240k','-preset fast','-strict -2','-b:v 320K','-bufsize 62000', '-maxrate 620k','-acodec aac','-ab 128k','-movflags +empty_moov'])
.toFormat('mp4')I get this log :
I hope someone can point me in the right direction. Thanks !
The client just gives an undefined error.
I hope someone can point me in the right direction.Thanks
