  lavc : include timebase in avcodec string at debug level.

• FFMPEG sound not playing in video converted from audio in browsers (chrome/firefox) except safari

  7 février 2019, par Bhavik Rathod

  Sound not playing in Video (mp4) converted from Audio (mp3), Below is my code

  I am using FFMPEG version 4.1

  ffmpeg -y -loop 1 -i background.jpg -i dia.mp3 -c:v libx264 -tune stillimage -pix_fmt yuv420p -c:a ac3_fixed -b:a 128k -shortest -vf "[in]drawtext=text=Hi:x=(w-text_w)/2:y=(h-text_h):fontfile=arial.ttf:fontsize=100:fontcolor=ffffff:alpha='if(lt(t,9.2763066666667),0,if(lt(t,9.2763066666667+1),(t-9.2763066666667)/1,if(lt(t,12.83428),1,if(lt(t,12.83428+1),(1-(t-12.83428))/1,0))))'" output.mp4 2>&1

  I have tried putting -movflags +faststart as an output option

  I am using ac3_fixed because i found that fix for handle memory management, My server is getting hang on using aac no video created nothing i have to restart instance to get back to work. by using ac3_fixed everything is perfect but issue is only sound playing in chrome and firefox.

  Below is full log while using aac
