Tokbox archived video is letterbox (black border around video)
28 août 2017, par Bijan MarkesI have archiving setup to save my tokbox publisher streams straight to an AWS S3 Bucket ; But the final saved archive.mp4 is appearing letter-boxed / has black borders around the stream video rather than stretching the video to fit the whole frame. Is there any way to change this ? It is completely on the tokbox end and I also have the fit-mode for the publisher set to "contain" although changing it to cover doesn’t change anything. Thanks.

ffmpeg transparent HVEC video from alpha matte and color video
16 janvier 2023, par JamesI have an alpha.mp4 (alpha matte video) and a color.mp4 (color video). How do I use ffmpeg to make a transparent HVEC (.mov) video ?


I can combine with ffmpeg to make a .webm file following the instruction here :
https://www.unscreen.com/api under "Convert unpacked Pro Bundle to WEBM video with transparency"


I have a newer mac and should be able to use HVEC_videotoolbox from either these 2 videos or the .webm file created.


The closest I found was this which seems to generate a corrupt video that cannot be viewed in safari. Use FFmpeg to generate a movie with alpha channel from separate video and fill movies ? but
