hello everyone,
i am an amateur，i compile the vlc media player for android, Firstly,thanks for their great work,
now i have one question, ask for your help:
i use my device to play RTSP streaming, but only audio without vedio, is this partial function under development or something wrong occured when i compile it？

thanks for your words～

The feature is not finished.

The feature is not finished.

thank you very much
i want to know that can the ‘libvlcjni.so’ deal with the rtsp streaming now？
in other words,what the unfinished part need is some other moudles or jni functions or just java code ？

forgive my poor english please

The java code.

The java code.

thank you very much,
i wonder if or not the function, within this project, that plays RTSP streamings enconded by H.264, could be run on Android 2.1.
what do u think? thanks.

Yes.

I can help on the Java code if needed. Just let me know what's missing there. Thanks for the great work!

I have tried the android VLC port and the only feature that does not work is the streaming.

I have tried on two tablets: galaxy 10.1(tegra2) and galaxy 8 (neon).
In both cases while the stream is delivered (video and audio flows through the network) the video is not displayed.
Audio is fine.

The message in the neon enabled device is "yuv_rgb_neon filter can't get output picture"
while for the tegra2 one is just "filter can't get output picture".

Any idea?

Thanks
Best.

sorry,i get the same problem,and try to solve, but i can't quite understand why 'libvlc_media_get_tracks_info' returns 0 and 'LibVLC_hasVideoTrack' returns false?
My test stream is encoded by H.264 + AAC.

because it uses the audio view.

because it uses the audio view.

I see,thanks very much

the .so file can be directly used in android 2.1 project?

in Project.Properties, i change the "target=android-14" to "target=android-7" , and cut some features i dont't need, it seen OK in the IDE, but can't run in my device(andriod 2.1).

You shouldn't have to change anything to make it work.
OpenSLES headers are required to build, but OpenSLES is only used on devices that can use it.

So you mean that vlc-ports/android cannot be compiled and then, run on Android 2.1?

It can be compiled and it works fine.

It can be compiled and it works fine.

i followed by the artical http://wiki.videolan.org/AndroidCompile
and compiled successfully,but just works fine on android 2.2 and above.
what's wrong?
Nothing should be changed. right?

thanks for your great help.

Hi Dapengwang,

I am also facing the same issues,
- Not able to stream video on phone (htc desire), but audio is working fine. and i have android 2.2+ aswell.
- But video and audio works fine from sdcard.
- Is it the problem only with RTP or also in HTTTP.?
- Is it a problem because of NEON?

please letme know, if you have sloved the issue. Thanks in advance.

Implemented in latest VLC Android git master.
