[FFmpeg-user] Make white of photo transparant
I am still experimenting with ffmpeg. At the moment I have the folowing: ffmpeg -y -ss 21:50 -to 23:20 -i input.MTS -i Photos/output.jpg \ -filter_complex "[0:v][1:v] overlay=0:-10:enable='between(t, 5, 85)'" \ -pix_fmt yuv420p -acodec copy -vcodec libx264 -preset veryfast -crf 26 \ output.mp4 The background of the photo is white. Would it be possible to make that transparent? (So where there is white, I do not see white, but the video.) -- Cecil Westerhof Senior Software Engineer LinkedIn: http://www.linkedin.com/in/cecilwesterhof ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

[FFmpeg-user] RTMP speed vlue never reaches 1 (100%), streamign fail in short time
Hello, I am trying streaming rtpm using ffmpeg but i have few problems. FPS has never reach 25fps, only 21 for example. So stream stopping and in short time (couple minutes) buffer overflow. Ffmpeg is unusable to stream using rtmp protocol. In complete scenario i need use tee muxer and send stream to rtmp and mpegts udp destination. When i leave only mpegts udp, streaming works fine.

Hello,
Could you share a URI for one of these videos?
Also, do they play on mobile before you add the text filter?
Cheers,

[FFmpeg-user] Problem with videos not playing in mobile browser
Dear all
I am new to this forum.
I have noticed that some of my videos, encoded with ffmpeg and uploaded
to my websites, do not play on mobile web browsers, but they work
perfectly well on desktop browsers on my Linux machine. I get either a
message saying 'file is corrupted' or no message at all (just a blank
video) depending on the browser. I've tried Brave, Firefox and Chrome,
on an iPhone, a Samsung tablet and a Samsung Galaxy s10 plus. The 'bad'
videos consistently fail to play on mobile devices.
I've run an ffprobe on two .mp4 files: one which works on a mobile and
desktop browser (good.mp4) and one which will only play on a desktop
browser (bad.mp4. These are partial outputs (the rest of the output for
the two files seems identical):
