• FFMPEG - Converting any kind of file to Mp4 compatible with IOS and Flash

  14 février 2021, par jax

  I am struggling with FFmpeg within Drupal Video Module to produce files to MP4 that is compatible with IOS and Flash Player10 and up.
I have used the following commands so far, please note that the variables starting with " !" are placeholders and will be replaces with the proper items :

  


  FFmpeg -strict experimental -y -i !videofile -pass 1 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -an !convertfile

FFmpeg -strict experimental -y -i !videofile -pass 2 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -acodec aac -ab 128k !convertfile


  


  The above command produce an error as :

  


  error executing command for rendering preset HTML5 MP4, command #1 :

  


  nice -n 19 /usr/bin/ffmpeg/ffmpeg -y -i '80137db8c3_1334836277_int_tr_19.mp4' -s 176x100 -b:v 500k -threads 0 -vcodec libx264 -preset slow -acodec aac -ab 128k '/converted/80137db8c3_1334836277_int_tr_19.mp4' 2>&1

Output:

The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
Alternatively use the non experimental encoder 'libfaac'.


  


  Another command that I used is :

  


  FFmpeg -i !videofile -an -pass 1 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile

FFMpeg -y -i !videofile -acodec libfaac -ab 128k -pass 2 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile

  The above command produces the file correctly however it cannot be played in flash player. One thing that I noticed is this may happen if the input file is mp4 as well. This command is executed for users uploading files, so the input file could be any format.

• Why is live video stream not fluent while audio stream is normal when they are played by Flash RTMP Player after being encoded

  1er décembre 2015, par xiaolan

  My video stream is encoded with H.264, and audio stream is encoded with AAC. In fact, I get these streams by reading a file whose format is flv. I only decode video stream in order to get all video frames, then I do something by using ffmpeg before encoding them, such as change some pixels. At last I will push the video and audio stream to Crtmpserver. When I pull the live stream from this server, I find the video is not fluent but audio is normal. But when I change gop_size from 12 to 3, everything is OK. What reasons cause that problem, can anyone explain something to me ?

• Flash 9, non-NetStream/movieStar can detect when playback fails due to missing sound hardware support (or 32-channel sound ceiling being hit.) Implemented as SMSound.onplayerror() callback.
