Public bug reported:
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

[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':

# avprobe output
