• How to get the information of bit-rate from YouTube videos ?

  21 février 2017, par Ashutosh Singla

  I was using YouTube videos for my test and I was wondering how can I get the information of bit-rate of the played video ?

  I used 2 methods to know the information about the bit-rate but didn’t get any information.

  1. Right-click on a video and choose "Stats for nerds".
  
  2. ffmpeg -i input_video -f ffmetadata metadata.txt

  I don’t know if by doing the right click on the video and then properties, then details would give me the correct way of showing the bit-rate.

  Any suggestions ?

  14 mai 2014, par Hamid Tanhaei

  i using ffmpeg to create a streamable mp4 video file for play online. but converted video try to load 3 - 4 MB data of video at start. then video can be play and seekable.

  i try to remove start load data by different ffmpeg commands. but each commands had problems.

  my first command(load 3-4 MB data of video at start and seekable) :

  ffmpeg -i file.mkv -movflags faststart -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 1.mp4

  and other commands(removed 3-4 MB load data at start and NOT seekable) :

  ffmpeg -i CloudywithaChanceofMeatballs.mkv -movflags faststart -frag_size 1024 -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 1.mp4
  
  ffmpeg -i DespicableMe2MiniMovie.mkv -movflags faststart -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 2.mp4
  
  ffmpeg -i DespicableMe2MiniMovie.mkv -movflags faststart -frag_size 10240 -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 2.mp4
  
  ffmpeg -i DespicableMe2MiniMovie.mkv -movflags faststart -frag_duration 2000 -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 2.mp4
  
  ffmpeg -i CloudywithaChanceofMeatballs.mkv -movflags faststart -frag_duration 2000 -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 2.mp4
  
  ffmpeg -i CloudywithaChanceofMeatballs.mkv -movflags frag_keyframe+empty_moov -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 2.mp4
  
  ffmpeg -i CloudywithaChanceofMeatballs.mkv -g 52 -movflags frag_keyframe+empty_moov -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 2.mp4

  i used this command too(it load 3-4 MB data of video at start and seekable like first code by ffmpeg) :

  MP4Box -add video.mp4 videos.mp4
  
  MP4Box -inter 500 video.mp4

  my video file duration is : 1h 34min and converted size is 100MB
