I still don't think this is a bug. If audio-recorder produces files with
colons in the name, it needs to ensure that avconv/avprobe is called
with file:.

Title:
  Cannot open file: avprobe mis-interprets some file names.

Status in libav package in Ubuntu:
  Invalid

Bug description:
  Hello,
  I am using audio-recorder to produce some audio files of types .ogg, .flac and .mp3.

  I just discovered that avprobe command cannot open the file names produced by the recorder.  Avprobe mis-interprets the file given as argument.  
  An example.

  $ avprobe -show_format -show_streams -pretty "2015-03-24-21:11:13.mp3"

  avprobe version 11.2-6:11.2-1, Copyright (c) 2007-2014 the Libav developers
    built on Jan 18 2015 05:12:33 with gcc 4.9.2 (Ubuntu 4.9.2-10ubuntu2)
  2015-03-24-21:11:13.mp3: Protocol not found
  # avprobe output
  ---

  Let's rename 2015-03-24-21:11:13.mp3 to test1.mp3.
  $ cp 2015-03-24-21:11:13.mp3  test1.mp3

  $ avprobe -show_format -show_streams -pretty "test1.mp3"
  avprobe version 11.2-6:11.2-1, Copyright (c) 2007-2014 the Libav developers
    built on Jan 18 2015 05:12:33 with gcc 4.9.2 (Ubuntu 4.9.2-10ubuntu2)
  [mp3 @ 0x146ad20] max_analyze_duration 5000000 reached
  Input #0, mp3, from 'test1.mp3':
    Duration: 00:04:41.86, start: 0.000000, bitrate: 92 kb/s
      Stream #0.0: Audio: mp3, 44100 Hz, 2 channels, s16p, 92 kb/s
  # avprobe output

  [format]
  filename=test1.mp3
  nb_streams=1
  format_name=mp3
  format_long_name=MP2/3 (MPEG audio layer 2/3)
  start_time=0\:00\:00.000000
  duration=0\:04\:41.861224
  size=3.109Mibyte
  bit_rate=92.536Kbit/s
  ...
  start_time=0\:00\:00.000000
  duration=0\:04\:41.861224

  And avprobe opens  test1.mp3 fine.
  -----------------------------------------------------

  Example 2:
  $ avprobe -show_format -show_streams -pretty "2015-02-20-22:21:25.ogg"

  avprobe version 11.2-6:11.2-1, Copyright (c) 2007-2014 the Libav developers
    built on Jan 18 2015 05:12:33 with gcc 4.9.2 (Ubuntu 4.9.2-10ubuntu2)
  2015-02-20-22:21:25.ogg: Protocol not found
  # avprobe output

  Rename it.
  $ cp 2015-02-20-22:21:25.ogg test1.ogg

  And now it works.
  $ avprobe -show_format -show_streams -pretty "test1.ogg"

  avprobe version 11.2-6:11.2-1, Copyright (c) 2007-2014 the Libav developers
    built on Jan 18 2015 05:12:33 with gcc 4.9.2 (Ubuntu 4.9.2-10ubuntu2)
  Input #0, ogg, from 'test1.ogg':

      Stream #0.0: Audio: vorbis, 44100 Hz, stereo, fltp, 160 kb/s
  # avprobe output

  [format]
  filename=test1.ogg
  nb_streams=1
  ...
  time_base=1/44100
  start_time=0\:00\:00.000000
  duration=0\:00\:55.183673
