Bug Description

It seems that running rMD (v0.3.8) on Oneiric, using JACK as audio input is broken:

*) If JACK is selected as audio input, clicking the "record" button immediately returns with the message:
"exited with status: 2816. Description: Improper window specification."

*) I've found a HowTo-website describing the exact same behavior:
(http://angel-de-vicente.blogspot.co.at/2011_01_01_archive.html)

"[...] you can click "Use jack for audio capture", but with this option enabled I always got errors like "... exited with status: 2816. Description: Improper window specification.", so I decided to record the sound (with Ardour) and the video (with recordMyDesktop) separately, and then mix it with Kdenlive."

Unfortunately, I want to use rMD to record Ardour itself - so I can't easily use his workaround.

*) With rMD set to record the regular "DEFAULT" device (without JACK), the video transcoding (after stopping the recording), shows the progress-bar - staying at 0% infinitely. Until I quit "qjackctl". Then the rMD transcoding window closes itself, and outputs a broken .ogv file.

*) When restarting the rMD GTK-GUI with "JACK" enabled as audio source, clicking "record", returns the following error message:
"exited with status: 4352. Description: Port registration/connection failure."

*) rMD also does not show up as JACK client at all.

Exactly the same what my rMD is showing.

I confirm this bug. I only have JACK available for sound. My system (KX Studio / Kubuntu 12.04) doesn't have PulseAudio installed so I have to use JACK.

I'm still seeing this on 12.04. Does anyone know if this is still an issue on 14.04?

Yes, I'm running Ubuntu 14.04 with recordMyDesktop v0.3.8.1 and I ran into the same error message.

Here's a bread crumb. I edited /usr/lib/python2.7/dist-packages/recordMyDesktop/rmdTrayIcon.py to dump the full command-line:

$ recordmydesktop -o /home/nhilton/Desktop/rmd1.ogv --fps 30 -x 527 -y 320 --width 877 --height 571 --channels 1 --freq 48000 --v_quality 63 --s_quality 10 --workdir /tmp --overwrite --use-jack system:playback_1 system:capture_1

> Window size specification out of bounds!(current resolution:1920x1080)

The windows parameters x, y, width, height all looked okay to me. So next I tried to running without any windows parameters:

$ recordmydesktop -o /home/nhilton/Desktop/rmd1.ogv --fps 30 --channels 1 --freq 48000 --v_quality 63 --s_quality 10 --workdir /tmp --overwrite --use-jack system:playback_1 system:capture_1

The window dimensions look odd, but then we get the underlying JACK error.

The window size out of bounds is caused by a bug at rmd_parseargs.c:197
That line should read something like...

          POPT_ARG_STRING | RMD_USE_JACK_EXTRA_FLAG, &arg_return->use_jack, RMD_ARG_USE_JACK,

This is only an issue if you use the --use-jack argument

There is also another typo at rmd_parseargs.c:115
And that line should read...

        { "y", 'y',

I checkout the latest code, made these changes, compiled and everything worked. I'm too lazy to make an official patch.

Enjoy
