    Move the probe loop from av_open_input_file() into its own method · 4245c6ec
    Micah F. Galizia authored
    av_probe_input_buffer() so that it can be reused. Here are a few
    differences to the original way things were probed:
    
    - maximum probe buffer size can be specified as a parameter.
    
    - offset within the stream to probe from can be specified as a parameter.
    
    - instead of seeking back to the start each time a probe fails, stream
      data is appended to the reallocated buffer. This lowers the amount
      of data read from the stream (there is no repetition) and results in
      fewer closed and reopened streams (when seeking fails).
