How to route input audio to output device at realtime on Android/iOS
6 août 2020, par NimethI'm working on Karaoke project for both Android and iOS where user could record their performances (their video and vocal) and I use ffmpeg for mixing music with their recordings. Anyway, I wish I could route/pipe user vocal at realtime (capture thru device microphone) to output device (speaker) so user could hear their voice at realtime applied with some level of echo (to produce an effect as if we were in classic karaoke room). Over weeks I have been struggling with searching the ways to implement that based on ffmpeg, but no luck. Please kindly help.


Many thanks in advance.

Multiple outputs from same source
28 septembre 2021, par Christian RHow do I modify this ffmpeg string to generate multiple outputs with different video bitrates ?
This to save time when yadif=1 take a lot of power. Also, can't get it to accept yadif_cuda in windows.


ffmpeg -y -f lavfi -i anullsrc=cl=mono:sample_rate=48000 -i "test.mxf" -vf yadif=1 -s 1920:1080 -c:v h264_nvenc -force_key_frames "expr:gte(t,n_forced*10)" -pix_fmt yuv420p -preset slow -rc vbr_hq -b:v 4.5M -map 1:v -map 0:a -c:a aac -b:a 192k -shortest "test.mp4"
