FFMPEG : MP4 videos are not playing properly in iPhone, iPod, iPad
26 janvier 2020, par Shakti SinghI am converting videos from m4v, flv to MP4 for iPhone, iPod, iPad.
I am using the below command to convert these videos
ffmpeg -y -i video_1336500693.m4v -vcodec libx264 -vpre slow -vpre
ipod640 -b 250k -bt 50k -acodec libfaac -ab 56k -ac 2 -s 480x320
video_1336500693.mp4The video part of this mp4 file is working fine but the audio is not working properly. I am using HTML5 for this.
The audio works for first 8-10 seconds but after that audio does not work and the strange thing is if I jump to forward or backward the audio works.
Can anyone suggest what’s going wrong ?

Bulk Edit Videos resolution/aspect problem
1er mars 2020, par buffe bufferaLets say i have 100 videos, all different dimensions and formats
I would like to know if there’s a way to bulk edit each video and set it to 16:9 1920x1080
If is possible would like to add blurred sides effectfor %%a in ("C :\Users\vmp\Desktop\Videos\100ClipsConcat*.mp4") do ffmpeg -i "%%a" -lavfi "scale=1080:640,boxblur=luma_radius=min(h\,w)/20:luma_power=1:chroma_radius=min(cw\,ch)/20:chroma_power=1[bg] ;[bg][0:v]overlay=(W-w)/2 :(H-h)/2,setsar=1" "C :\Users\vmp\Desktop\Videos\100ClipsConcat\Blurred\%% na.mp4"
pauseIve tried this and it blur add video but resolution isnt good
Ive also tried to do that :
ffmpeg -i 2.mp4 -lavfi "scale=ih*16/9 :-1,boxblur=luma_radius=min(h\,w)/20:luma_power=1:chroma_radius=min(cw\,ch)/20:chroma_power=1[bg] ;[bg][0:v]overlay=(W-w)/2 :(H-h)/2,crop=h=iw*9/16,setsar=1" r3.mp4
It blur every video perfectly but it also increase resolution a lot
I would just like to find something that convert each video to 1920x1080 16:9 (if is possible with blur effect)
