Hi all! tl;dr
What's the best codec & fps (and other CLI config) to minimize bandwidth usage for streaming text editor videos? Specifically: * high res (as close to original as possible) * low fps (< 8 is fine) * low color count * no audio _________ Details: I want to stream video from a USB video capture device (using nginx). The incoming video is of text editing for the most part, so I guess difference between frames would be minimal 9/10 times. Color loss is acceptable, but fonts should remain sharp. I have found that `ffmpeg -f v4l2 -i /dev/video0 <extra config> rtmp://localhost/live/test` is the basic template I need to follow. Of all the combinations of codecs/framerates I tested, the only thing that works without killing itself is `-f flv`. If I try to suggest framerates, it works for 1-2 seconds and dies with `[flv @ 0x...] failed to update header with correct duration/filesize`. Not specifiying a codec gives some NULL error. mp4, x264, mpeg4, mpeg2video don't work. I was hopeful for VP8, but `-f VP8` doesn't work. mpegts works but dies as soon as vlc tries to open it (without streaming anything). Please advice. Thanks. _______________________________________________ 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".
