libavformat : Account for negative position differences in ff_configure_buffers_for_index
24 mars 2023, par Martin Storsjölibavformat : Account for negative position differences in ff_configure_buffers_for_index
When scanning through the index, account for the fact that the
compared samples may be located in an unexpected order in the file ;
this function is mainly interested in the absolute difference between
file locations.Signed-off-by : Martin Storsjö <martin@martin.st>

Mix audio input with video to specific location with FFmpeg
26 septembre 2016, par user2364292I created small video editing tool with which you can put some overlay images to the video and show them at specific locations and durations (filter : overlay=enabled(from, to...), etc.).
Now I also want to add some short audio sounds on the same way like pictures -> adding them to a specific time in the video. That means that overlays and audio sounds should be in one command if possible. I am using amix to merge all sound channels (video.mp4 and sound.mp3) but the thing is that they both start at the beginning. I tried with adelay=1500 but then I actually delay one channel that means I hear duplicate sounds with 1.5 sec delay. So I would like to delay only sound.mp3 input. Am I doing something wrong ?My try was that :
-i video.mp4 -i sound.mp3 -filter_complex amix -preset ultrafast -vcodec libx264 -r 24 -profile:v baseline -threads 14 video_output.mp4
Thank you very much !
