EOFError when loading Mp3 about pydub HOT 7 CLOSED

After inspecting the code, this seems to be a problem with the pre-compiled version of ffmpeg in Ubuntu 12.04, which is failing with the error:

ffmpeg: relocation error: ffmpeg: symbol avformat_alloc_output_context2, version LIBAVFORMAT_53 not defined in file libavformat.so.53 with link time reference

After uninstalled the ffmpeg package and compiling it from scratch following https://trac.ffmpeg.org/wiki/UbuntuCompilationGuide, it seems to work fine.

This issue aside, it might be a good idea in audio_segment.py to change:

subprocess.call(ffmpeg_call, stderr=open(os.devnull))

to:

subprocess.call(ffmpeg_call, stderr=sys.stderr)

so the user can see a more direct error message. Not seeing that wasted a lot of my time.

I wonder if there is a good way to make this user configurable. ffmpeg can be quite verbose and most of the time it's not useful information for pydub to output to stderr (showing the progress of the operation).

How would you feel about capturing ffmpeg's stderr and only outputting it to sys.stderr if ffmpeg returns a non-zero (error) status code.

What about logging? if the user is logging her application she will be able to see the log anyway.

Checking the exit code for a non-zero value makes sense.

Hi, I also have a problem with playing an mp3.

from pydub import AudioSegment

u=AudioSegment.from_mp3("yourself.mp3")
Traceback (most recent call last):

would anyone help me? Thanks!

@Ratnaganadi It looks like you don't have ffmpeg installed, or if it is installed, pydub can't find it.

@Ratnaganadi You may want to take a look at the Getting ffmpeg set up section of the read me :)
