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

Hi rowa,

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

Thanks & Regards,
Jickson

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

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

Sorry for that.

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

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

Thank you Rowa for the help.

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

It seems like the timing got messed up.

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.

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
