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

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.

Some notes:

  • The binary is ffmpeg; not FFmpeg or FFMpeg.

  • -strict experimental should be used as an output option. You are using it as an input option and is being ignored. You won't need it for other AAC encoders.

  • -threads auto is now default and adding it is superfluous.

  • You compiled with --enable-libfdk-aac, and therefore you can use -codec:a libfdk_aac which will provide better quality per file size than the other AAC encoders. See the FFmpeg AAC Encoding Guide and FFmpeg and x264 Encoding Guide.

  • The message Please use -b:a or -b:v, -b is ambiguous should not be ignored so ffmpeg knows if you want to apply your desired bitrate to the audio or video.

  • I don't see why the second command shouldn't work in a flash player. You may simply not be waiting long enough for the file to download completely before playing. You can add -movflags +faststart to allow playback to begin before the download completes.

  • Replace -s with the scale filter so you can have a proper filterchain with pad. Next time show actual commands and not commands with variables; otherwise I could have given a proper filtering example.
