FFMPEG scaling video disable viewing it while process is not ended, for video transcoding on the fly
5 juillet 2022, par Lucas FGood day all,


I'm working on a video player with 1080p original video files, and I would like to change their resolution on the fly :


Actually I host all my original video files under a web mp4 1080p format, and I would like to be able to offer 720p, 480p, etc ... qualities.


So I started to look for tutorials about video transcoding on the fly and I found the FFMPEG tool.


I'm actually using the following command to scale videos - to 720p for e.g. :


ffmpeg -i input.mp4 -vf scale=-1:720 output.mp4



The problem is, once FFMPEG starts scaling it, I have to wait the end of the process before being able to play the video. Do you know if there is any parameter for this command to allow playing the video while it's under scaling ?


Or any workaround that can help me doing this ?


Thank you in advance for your help !


EDIT


Now I found how to access readable content while transcoding (by transcoding to fragmented MP4) :


ffmpeg -i input.mp4 -vf scale=-2:720 -movflags +frag_keyframe+separate_moof+omit_tfhd_offset+empty_moov output.mp4



But my problem is when opening the video it comes as an "ended" video of the current transcoded data.


So if video lasts 1min and is half transcoded, I'll see only 30s, it will not load more data, once the rest is transcoded.
