Hello, I have modify the gstreamer in arm platform so that it can play mpg,ts,avi,rmvb,flv and so on video container formats, at the same time, we have a good comp ability with video container.
But it can only run on ARM, not in x86 and MIPS.
Do you have any good advice? Any kind of advice would be much appreciated!
Best Regards,
Hai Wang

Hello,
I would gladly share what I have with you. Hopefully, you can help me solve a problem I'm facing.
Tell me what you've done so far, where you have reached, and what issue is stopping you.
As for what I've done, here is a summary:
1- I'm using Android-x86 port from http://www.gingerbread-x86.org/ gingerbread-x86 branch.
The version I'm using is 2.3.5
2- I cloned the gstreamer_aggregate folder and the framework/base folder from the git as decribed on collabor.co.uk
However, since the framework/base is that of 2.3.2, I couldn't just replace the one in 2.3.5, so I left it out of my android-x86 tree.
This meant that I had to make a diff between the 2.3.2 and 2.3.5 framework files, whenever the compiler stops with an error. I did this so that I only put the changes required by gstplayer to work. Not much is required.
3- I replaced all arm references in the Android.mk files particularly --host=i686-pc-linux-gnu
4- I added the switch --disable-asm in gstreamer_aggregate/x264/Android.mk (although I might set this back to see if I can get it to work)
5- I'm still looking for an implementation of "gst_codec_utils_h264_get_level_idc", at the moment I have an approximate "dummy" implementation.
6- I compiled several times, and worked through little changes that I had to make with the mk files.
The above is quite simple, managed to get this far in one afternoon...
Eventually it compiled and worked partially. As I mentioned, mp3, ogg files play without a problem from with in Android UI. Videotestsrc overlays the output on top of the android gui. However, I keep getting a missing-plugin message when I try to play any video file.
Have you come across the missing plugin issue on your ARM device?
Can you please tell me, how many plugins list when you run gst-inspect on your ARM device? Also, where are the .so files of the plugins located?
Hope the info I gave you is helpful. If you tell me how much you progressed, I might be able to help you more.
Regards,

Hello,
First off, fantastic work done on porting gstreamer to android. Big thanks
to all.
I've managed to use the modifications to modify the android-x86 tree
and successfully and compiled gstreamer on android-x86
So far, I can play mp3 and ogg files from with in Android. I managed to run
"gst-launch videotestsrc ! surfaceflingersink" and saw the video
test overlay-ed at the top left corner of the screen.
And although gst-inspect states 140 plugins, 9 black listed, and 482
features, Every time i try to play a video file ( mpeg, mpg, divx, asf,...)
I get a missing-plugin in the logs.
I believe the good, bad and ugly plugins have compiled successfully.
However, I'm not sure if gstreamer is picking them up. I had to do a sym
link to the gst-plugin-loader since a warning message was showing that it
cannot be found. But even with the warning message gone, I'm still getting
the missing-plugin message in the logs.
Any help is highly appreciated. Looking forward for some feed back.
Thanks in advance,
-Shady
Note: I've posted this on the google group "android-gstreamer" as well.

Hi, I have solve the video file play on ARM, but I don't solve the peoblem
in x86, and do you have interest that we share each other's solution?
Best wishes.
