Snapshot of RTSP Streaming Android

[jickson.tj]

Hi All,

Is it possible to take snapshot of RTSP Streaming in Android?

Thanks & Regards,
Jickson

[edwardw]

Not out of the box.

[rowa]

1)enable the sout module in configure.sh
2)add 'enable-encoder=png' in rules.mak
Then the function of snapshot will be available

[edwardw]

This is not officially supported.

Hi rowa,

I see many rules.mak inside source directory. In which file I need add 'enable-encoder=png'?

Thanks & Regards,
Jickson

[edwardw]

vlc/contrib/src/ffmpeg/rules.mak

Hi,
Thanks for guiding.

After doing that change, I am getting the following error message when I ran compile.sh file.

how to resolve this issue?

[edwardw]

Update your protobuf.

[jickson.tj]

I have updated to protobuf 2.6.1. still I am getting the above error.
Can you please tell me how to resolve the following error.

/obj/local/armeabi-v7a/objs-debug/vlcjni/libvlcjni.o:libvlcjni.c:vlc_static_modules: error: undefined reference to 'vlc_entry__vod_rtsp'

Initially when i enabled sout, I got many errors like,

error: undefined reference to 'vorbis_encode_setup_vbr‘

and

undefined reference to 'vlc_entry__access_output_udp

I followed this http://blog.csdn.net/a358763471/article ... s/38331837 to resolve these issues.

But I didnt get any solution to resolve error related to "vlc_entry__vod_rtsp"

Please guide me resolve this issue.

[edwardw]

Probably you should not interfere with the build system like that.

[jickson.tj]

Sorry for that.

Is it possible to resolve those errors without changing the build system?

[rowa]

according to your error log, I think you could add the module 'vod_rtsp' and 'chromecast' to the blacklist and retry.

[jickson.tj]

Thank you Rowa for the help.

Error related to protobuf library is resolved by adding "-lprotobuf" to "LOCAL_LDLIBS" in Android.mk file.

[jickson.tj]

Snapshot is working now. But After taking snapshot, video is stuck , but audio continue to play. After few seconds audio/video both stops. How to resolve this issue?

It seems like the timing got messed up.

[jickson.tj]

ok. Is it possible to resolve timing issue?

[jickson.tj]

I checked the source code.

In below function "for" loop is getting stopped after taking snapshot.

Code: Select all

/***************************************************************************** * Thread: video output thread ***************************************************************************** * Video output thread. This function does only returns when the thread is * terminated. It handles the pictures arriving in the video heap and the * display device events. *****************************************************************************/ static void *Thread(void *object) { vout_thread_t *vout = object; vout_thread_sys_t *sys = vout->p; vout_interlacing_support_t interlacing = { .is_interlaced = false, .date = mdate(), }; mtime_t deadline = VLC_TS_INVALID; for (;;) { vout_control_cmd_t cmd; /* FIXME remove thoses ugly timeouts */ while (!vout_control_Pop(&sys->control, &cmd, deadline, 100000)) if (ThreadControl(vout, cmd)) return NULL; deadline = VLC_TS_INVALID; while (!ThreadDisplayPicture(vout, &deadline)) ; const bool picture_interlaced = sys->displayed.is_interlaced; vout_SetInterlacingState(vout, &interlacing, picture_interlaced); vout_ManageWrapper(vout); } }

What causes the video rendering thread to stop?.. please guide me in resolving this issue.

[jickson.tj]

I modified the function "ThreadControl" inside video_output.c file.

Code: Select all

case VOUT_CONTROL_SUBPICTURE: //ThreadDisplaySubpicture(vout, cmd.u.subpicture); cmd.u.subpicture = NULL; break;

Commented the function ThreadDisplaySubpicture.
Video is playing properly after taking snapshot now.

Thanks all for the help.

Thanks & Regards,
Jickson
