Arista Doesn't Work With openSUSE #134

Open arnieswap opened 12 years ago

arnieswap commented 12 years ago

When I try to transcode movies for Android Tablets using Galaxy Tab or Android Droid X preset, Arista throws error 'can't add item due to missing elements"

danielgtaylor commented 12 years ago

Please make sure you've installed the relevant GStreamer plugins, e.g. gstreamer-plugins-bad/ugly and gstreamer-ffmpeg.

Take care, Daniel

Yes all those packages are installed. I installed codecs from [http://en.opensuse.org/Restricted_formats]

Output

The error it throws is Cannot add conversion to queue because of missing elements!

Does gst-inspect-0.10 x264enc show anything in the terminal? You need to have the x264enc element installed for most of Arista's presets to work properly. Perhaps that is missing from the system packages, or is renamed or something?

Take care, Daniel

gst-inspect-0.10 x264enc

Output No such element of plugin 'x264enc

Best wishes Swapnil

danielgtaylor commented 12 years ago

I would file a bug with your distribution or ask what package you need to install to get the x264enc gstreamer plugin. Without it you can't do all that much with Arista.

Take care, Daniel

@danielgtaylor Thanks. That will help us a lot. I will keep an eye on the page.

I tried to install some packages and now I get this error:

Conversion of The_Iron_Lady.mp4 to Generic Android Droid X failed! Reason: Unable to construct pipeline! no property "profile" in element "faac0"

danielgtaylor commented 12 years ago

That is a GStreamer issue - you should file a bug with OpenSUSE's GStreamer package. It's possible it is out of date or has some non-standard patches applied. You may refer to this bug when you file one there so they know the context.

Thanks I already filed a bug with them. https://bugzilla.novell.com/show_bug.cgi?id=753234 Thanks. Swapnil

gst-inspect faac indeed shows that there is no profile property in the faac element. But I neither see it in the code: http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/ext/faac/gstfaac.c

It looks like a problem in arista (or the profile), not in the openSUSE packages.

danielgtaylor commented 12 years ago

It is there, take a look at e.g. lines 85, 91, 108, 415, 441-451, 598-617, etc.

OK, it's a property of the source pad, I didn't look there. But in such a case a gst-inspect shows the element provides it.

It's really difficult to me to see anything wrong in the packages. Can you confirm that you can use the "Droid X" preset with GStreamer 0.10.36 and gst-plugins-bad 0.10.23?

Since I don't speak Python it would be a bit difficult to me to debug this. If it works for you, can you give a "gst-launch" line equivalent to what arista does when using the Droid X preset?

reddwarf69 commented 12 years ago

OK, I actually looked in the correct place before. The problem is this commit: http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/commit/ext/faac/gstfaac.c?id=6702de4237f6e7c3166b2807150669557220c44f Arista doesn't work with the latest version of the faac element.

I don't really know GStreamer so well to say if this is a bug or not. But you should either stop depending on the faac element providing that property or open a bug report with GStreamer for breaking your app.

reddwarf69 commented 12 years ago

To finish it. 0.10.23 was the first version of gst-plugins-bad to include this change. And to make it work, instead of "faac bitrate= profile=LC", "faac bitrate= ! audio/mpeg, base-profile=lc" must be used.

danielgtaylor commented 12 years ago

Interesting. For now you can manually update your preset .json file with that new string and things should work for you.

In the future, I'll have to detect the version and act accordingly, which means probably overriding or transforming the presets... this will be kind of a pain.

Thanks that solved the problem and now I am able to transcode videos. I will write about it to help other users as well. Thanks again.

kapouer commented 11 years ago

Actually i had to just remove profile key, since base-profile doesn't work either here on debian/sid + deb-multimedia.
