Getting error while opening encoder for output stream trying to convert to html presets

Could you post the log messages that you are receiving?

Fmpeg failed to transcode test upload.mp4.
Reported errors

PHPVideoToolkit error: Execute error. It was not possible to encode "D:\xampp\htdocs\drupal7\exercises\videos\original\test upload_2.mp4" as FFmpeg returned an error. Note, however the error was encountered on the second pass of the encoding process and the first pass appear to go fine. The error is with the video codec of the input file. FFmpeg reports the error to be "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height".
