• FFmpeg - Buffer queue overflow, dropping - when combining 2 videos and using concat, hstack and trim

  23 août 2018, par Mayank

  I am trying to merge two videos using concat and hstack but getting buffer overflow error resulting in the one of the video getting paused for few seconds.

  I tried adding fifo and h264 video codec as suggested on this forum but the issue persists.

  Can someone please let me know the issue in this command ? Many thanks in advance.

  ffmpeg -i 1_a.opus -i 2_a.opus -i 1_v.mp4 -i 2_v_bars.mp4 -filter_complex "[1:a]adelay=15720|15720[a1]; [0:a][a1]amix; [3:v]trim=0:15.81,geq=0:128:128,fifo [silence]; [silence][3:v]concat,fifo [3_v_silence]; [3_v_silence][2:v]hstack,fifo" -vcodec libx264 -strict experimental -y out_fifo_h264_2.mp4
