Public bug reported:

I have Ubuntu 11.10 and I installed Openshot through the ppa. I have the
latest version, that is, 1.4.1.

I'd like to report a couple of bugs that I found, the first of them
driving me crazy. I simply couldn't export using codec x264 (I had sound
but no video) and I looked at all the possible solutions, updating MLT,
checking python libraries, etc. Well, it was all much simpler than that.
The file "video.py"
(/usr/lib/pymodules/python2.7/openshot/classes/video.py) has this
problem, at least for me, since everytime I tried to render files using
libx264, I had the following output:

[NULL @ 0x22e0900] [Eval @ 0x7fa2259f34c0] Invalid chars '.6' at the end of expression '0.6'
[NULL @ 0x22e0900] Unable to parse option value "0.6"
[libx264 @ 0x22e0900] broken ffmpeg default settings detected
[libx264 @ 0x22e0900] use an encoding preset (e.g. -vpre medium)
[libx264 @ 0x22e0900] preset usage: -vpre <speed> -vpre <profile>
[libx264 @ 0x22e0900] speed presets are listed in x264 --help
[libx264 @ 0x22e0900] profile is optional; x264 defaults to high

All I needed to do was the following:

if self.render_options["vcodec"] == "libx264":
					self.c.set("minrate", "0")
					self.c.set("b_strategy", "1")
					self.c.set("subcmp", "2")
					self.c.set("cmp", "2")
					self.c.set("coder", "1")
					self.c.set("flags", "+loop")
					self.c.set("flags2", "dct8x8")
					self.c.set("qmax", "51")
					self.c.set("subq", "7")
					self.c.set("qmin", "10")
					self.c.set("qcomp", "0.6") ---> changed the value for "0,6", using a comma
					self.c.set("qdiff", "4")
					self.c.set("trellis", "1")

The second one is much less important, but it also has to do with
commas. Every time I click of preferences and I close the menu, on my
"config.xml" file the value of the image size changes from "7" to
"7,00", again giving me the following mistake:

self.valImageLength.set_value(float(self.form.settings.general["imported_image_length"]))
ValueError: invalid literal for float(): 7,00

I haven't been able to fix it yet except by accessing the "config.xml"
file and changing it manually to the default value, that is, "7".

I think these issues can be easily fixed, so I hope that our developers
include them for the future.
