• FFMPEG : Error writing trailer of v%v/index.m3u8 : Cannot allocate memory

  I wanted to convert one video track and 2 audio tracks to HLS by combining them.
That means, the HLS conversion has to be multi-bitrate and multi-language both.

  


  What do I want to achieve ?
I have to prepare an HLS stream for 3 resolutions, namely, 720px, 480px and 360px.
Also, there will be 2 audio tracks in the resultant stream, one English and another Hindi.
I am running the below command and getting the error as described below.
Can anybody help me out ?

  


  Command :
