pros and cons of C++ vs Python - opinions please
 
|
I will soon be developing a gstreamer replacement for a VLC application.
I have been a C++ programmer for over 20 years, working with gstreamer
for the last 2. I could almost build the code (OK, I would have to
research the plugins) in my sleep. But there is this new thing (not
really, but somewhat) called Python that works with gstreamer. The
application that I will develop is stand-alone in the sense that it is
invoked from a different application. What are the relative merits of
using Python vs. C++? Currently, no one in our shop does Python so this
would be the first app. I can't say if it would ever be the only app.
Thank you for different opinions. Chuck Crisler

Greetings Chuck,
I think the obvious difference is that C++ compiles to native and with python you'd need to install some levels for language interpretation. And I'm a proponent for sticking with what you know. /Loren On Wed, Jul 18, 2012 at 10:33 AM, Chuck Crisler <[hidden email]> wrote: > I will soon be developing a gstreamer replacement for a VLC application.

Chuck Crisler Personally, I'd go with Python, but that's my bias. There are really only 2 disadvantages to using Python, in my opinion: 1) Memory overhead - if you need your app's memory footprint to be as small as possible (say for mobile/embedded), Python isn't the right choice. 2) Startup time - Python will probably add at least 100-150ms to a warm start. That said, I feel it's often easier to make a fast starting Python app because you can iterate more quickly on solving what (likely) is actually making your app start slowly (needless synchronous IO, other silly stuff) I'd also say that the harder the problem domain is, the more I'd recommended Python. However, building a video player with GStreamer is very easy... there are extremely high-level building blocks. So a video player is a place I'd at least consider using C (or in your case C++), despite my heavy Python bias. I just happen to have same bare-bones Python video player examples handy, so you can see what it takes. This is GStreamer 0.10 (static Python bindings): http://bazaar.launchpad.net/~jderose/+junk/gst-examples/view/head:/video-player-0.10 This is a port of the same to GStreamer 1.0 (PyGI): http://bazaar.launchpad.net/~jderose/+junk/gst-examples/view/head:/video-player-1.0 Of course, as they say, "use what you know", so factor that in too. Have fun! ______________________________________________ > gstreamer-devel mailing list > [hidden email] > http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel > _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Need more info on your architecture. Generally speaking though, I agree with previous comment ... stick to what you know unless it is really unsuited to what you are trying to accomplish. How will you need to distribute your application? Also, Vala has some nice bindings to gstreamer as well, if that appeals to you.

It depends a bit on the C++ "flavour" you're after as well. If you are happy to just use the GStreamer C API and build your application in C++, that would be my recommendation. Otherwise there are GStreamer-Qt and GStreamermm (Gtk) C++ bindings for GStreamer, but the problem with these is that there is not a huge user base for them and that there are no major applications (yet) that use them, so they've had considerably less exposure in real-world applications than, say, the python-gst bindings. If you don't have other reasons to switch to python, I wouldn't do it just for this (but if you do, you should be aware of the upcoming gst-0.10/python-gst to gst-0.11/1.0/py-gi transition).

I would suggest to take a look on Vala - it has syntax close to C# but
compiles down to native code, and is designed to work well with GObject-based libraries, such as GStreamer. You will gain both nice syntax and efficiency. m. 2012/7/18 Tim-Philipp Müller <[hidden email]>: > On Wed, 2012-07-18 at 10:33 -0400, Chuck Crisler wrote: > >> I will soon be developing a gstreamer replacement for a VLC >> application.

That's a good point, which I was ging to raise. python-gi is still quite difficult to use because it doesn't document itself very well, although improvements are on the horizon <https://bugzilla.gnome.org/show_bug.cgi?id=679804>. But I didn't get a reply to my question here about how to read a list of GstStructures from a field of a parent GstStructure in python-gi/gst-0.11, so maybe it isn't possible yet, or if it is nobody knows how! :-/ _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

I agree with mostly with "stick to what you know unless is really
necesary to use anything else". But, and this is just my own story. Recently I started building an app using gstreamer for multimedia handling and I started using python, cause it seemed easy, I've been programmed with python before so I'm not new to the language. The main problem I encountered was the bindings, you're adding a layer of complexity just by using python wrappers over the C API. What I recommend is to build your app using C++ and use C API of gstreamer which is documented, tested and easy to debug. As said in the thread there's C++ bindings, but I'd stick to the C API as much as I could.
