• convert h.264 avi container to mp4 with ffmpeg

  31 août 2014, par Tom

  I’d like to convert my h.264 avi container to a mp4 container with ffmpeg. I’ve found this works :

  This generates a file that I can play with the HTML5 video player but for legacy browsers I’d like to use a flash player (Flowplayer). The file doesn’t play with Flowplayer, in fact it causes it to crash.

  However if I use :

  This works great. But the timing is quite different not to mention CPU cycles. The first command is measured in milli-secs while the second can take quite some time ( 5-40secs).

  Is there another way I can convert the avi to a mp4 container quickly ? Ideally by re-muxing as opposed to re-encoding.

  EDIT

  I’m using this right now which I find to be the fastest for re-encoding. But again I’d rather not do this. I just want to re-mux the code.

• correctly escaping text in drawtext filter

  According to documentation %{}:, should be escaped with slash. But when I escape % the text is not added. There's error message saying Stray % near ')'. But what does it mean and how I can fix it ? Command and output :
