Desktop example youtube-dl broken.

Trying to access /usr/bin/ffmpeg when called with arguments. When called with no arguments, tries to compile code!?

AppArmor denials when called with no arguments:

The access to /usr/bin/ffmpeg indicates you were hitting bug #1570581 which is fixed now. I suspect that this app is not shipping ffmpeg in the snap. If it is, if you retest the ffmpeg denial should go away.

[Daniel Holbach (dholbach)]

Confirmed. I'm adding ffmpeg to the branch. The only issue we now can still see is writing to CWD.

[Daniel Holbach (dholbach)]

It looks like dpm already added ffmpeg to the snapcraft.yaml - why do you build it from source though? Wouldn't

stage-packages: [ffmpeg]

be easier?

I also can't seem to run it:
daniel@daydream:~/dev/snappy/snappy-desktop-examples/youtube-dl$ youtube-dl.run --help
/bin/sh: 0: Can't open /snap/youtube-dl/100002/command-run.wrapper

Works fine here. Make sure to connect the "home" plug for allowing it to write the downloaded file.

$ sudo snap connect youtube-dl:home ubuntu-core:home

$ youtube-dl.run ytsearch:ubuntu

I get this when trying to connect the plugs:

error: cannot perform the following tasks:
- Connect youtube-dl:home to ubuntu-core:home (cannot connect plug to slot "home" from snap "ubuntu-core", no such slot)
