On Windows we should check also for the .exe filenames.
Thanks @archagon from #438

This should work on Windows by default. We'll have to check the subprocess call.

@FiloSottile Windows building is seriously broken right now, and it only seems to work on your system. On my system , even the (interactive!) Python installation fails with

err:msi:ACTION_InstallFiles compressed file wasn't installed (L"C:\\Python27\\Lib\\distutils\\filelist.py")

(I'm looking for a solution, but it's messy. Well, duh, it's Windows.)

Can you rebuild the binaries with a new release number and then release it?

Sure, will do ASAP! Can I merge a couple of PR before? (audio-extract progress, Google Plus IE, small fixes)

I know that the wine building is a mess, but @Tailszefox in #443 seems to have achieved it, so there are probably versions-related issues. (The interactive installation only happens the first time, building the environment) Let me know if I can help you with it.

The installation of the building environment when trying to compile the Windows version under Linux itself worked nicely for me, creating the prefix and all. The only thing I had to do was to change some parts of the script for it not fail near the end.

Note that the resulting exe doesn't work with Wine for me (throws a Could not load python dll error), but it does work nicely on a native Windows XP installation.

The m4a file downloads in fine working conditions, it's just the post-processing where the issue arises. In all honesty, I don't think it's related to YTDL, as there seems to be an issue with ffmpeg's ability to load lame:

I found a few references to the errors, but no substantial information. If you all think it's ticket-worthy, I'll open one, or if you're confident that the issue is unrelated to YTDL, I will let it be. Feel free to point me in the right direction if this has been discussed.

@Tailszefox commented on GitHub (Jun 14, 2014):

From what I'm seeing, it does seem unrelated, since the issue comes from ffmpeg, though it would be nice if you could run the command youtube-dl tries to execute on its own to see what output you get.

The command should be ffprobe -show_streams filename. youtube-dl then looks for the "codec_name=" entry, and then the "codec_type=audio" entry. I assume it's unable to find them here.

How did you install ffmpeg? If you used homebrew or the like, it's possible you got a version without lame. Either try to find a version with it, or try compiling ffmpeg on your own, making sure to include lame.

Thanks for the reply @Tailszefox. I actually provided the output of running ffmpeg with no arguments to demonstrate the general error that the program output on any run, regardless of the arguments

I downloaded and installed ffmpeg through homebrew. Oddly enough, the -x audio extraction youtube-dl option (i.e. running ffmpeg) has worked for me in the environment in the past. So I am not sure if I installed an bad update or what. I seem to have ffmpeg and lame installed, but the library that ffmpeg is looking for (which is noted in the error message), if not there:

person@place {/a/directory}: which ffmpeg

person@place {~/a/directory}: ls -latr /usr/local/lib/libmp3lame.0.dylib
ls: /usr/local/lib/libmp3lame.0.dylib: No such file or directory

I am trying to track that library down. If I can't, would you suggest I uninstall/reinstall lame, or compiling on my own?

I found out this was due to faac libraries existing in /usr/local/Cellar..., but not in /usr/local/lib, so I linked those too and that seems to have solved the errors.

Now, however, there does appear to be a youtube-dl issue:

[download] 100% of 2.01MiB in 00:02
[youtube] Post-process file Freddy Cannon Tallahassee Lassie-4pgbJaKemic.m4a exists, skipping

I am not sure if I am using the -x flag incorrectly, but I was under the impression that it should convert the original m4a (video) file that was downloaded to an .mp3 audio file. The post-processing message suggests that its trying to convert to m4a, which already exists... I don't know, maybe I am using the command incorrectly.

I will keep poking around and post back if I sort it out.

THANKS FOR THE HELP!

@orangeoval commented on GitHub (Jun 14, 2014): well, I found that library in (/usr/local/Cellar/lame/3.99.5/lib) and linked it to the location noted in the error, where ffmpeg was looking (/usr/local/lib), and that resolved that error, but a new error is resulting: person@place {~/a/directory}: youtube-dl -x https://www.youtube.com/watch?v=4pgbJaKemic --verbose [debug] System config: [] [debug] User config: [] [debug] Command-line args: ['-x', 'https://www.youtube.com/watch?v=4pgbJaKemic', '--verbose'] [debug] Encodings: locale UTF-8, fs utf-8, out UTF-8, pref UTF-8 [debug] youtube-dl version 2014.05.31.4 [debug] Python version 2.7.5 - Darwin-13.2.0-x86_64-i386-64bit [debug] Proxy map: {} [youtube] Setting language [youtube] 4pgbJaKemic: Downloading webpage [youtube] 4pgbJaKemic: Downloading video info webpage [youtube] 4pgbJaKemic: Extracting video information [youtube] 4pgbJaKemic: Encrypted signatures detected.

Now, however, there does appear to be a youtube-dl issue: [download] 100% of 2.01MiB in 00:02 [youtube] Post-process file Freddy Cannon Tallahassee Lassie-4pgbJaKemic.m4a exists, skipping I am not sure if I am using the -x flag incorrectly, but I was under the impression that it should convert the original m4a (video) file that was downloaded to an .mp3 audio file. The post-processing message suggests that its trying to convert to m4a, which already exists... I don't know, maybe I am using the command incorrectly. I will keep poking around and post back if I sort it out. THANKS FOR THE HELP!

@orangeoval If you want to get the audio in an specific format you must use the --audio-format option, in that case: --audio-format mp3. The default behaviour is to extract the audio in the best format possible, and m4a actually only contains the audio.
