SharedFdPipe.cpp in OpenMAXIL/src/content_pipe/shared_fd_pipe generates illegal seek error when socket or pipe is used as output of Andriod media recorder

[mjoa]

Hi,

is it possible to stream output from Android media recorder using socket or pipe to another NDK application on the same i.MX device that in turn streams it out? I have tried the followings to set outputfile of media recorder:

// recorder.setOutputFile("/data/data/com.persistentsystems.videocast/files/pipe0"); //pipe

//            recorder.setOutputFile(pfd.getFileDescriptor()); //socket

            recorder.setOutputFile("/sdcard/test_video.mp4"); //file

SharedFdPipe.cpp (proprietary code of Freescale) in OpenMAXIL/src/content_pipe/shared_fd_pipe generates illegal seek error when socket or pipe is used

as output of Mediarecorder:

02-11 21:53:14.560 I/OMXPlayer( 3658): LEVEL: 1 FUNCTION: SharedFdPipe_Open LINE: 39

02-11 21:53:14.560 I/OMXPlayer( 3658): SFD open sharedfd://28:0:0

02-11 21:53:14.560 I/OMXPlayer( 3658): LEVEL: 1 FUNCTION: SharedFdPipe_Open LINE: 59

02-11 21:53:14.560 I/OMXPlayer( 3658): seek to pos: 0 failed, errno: Illegal seek

When file is used as output of media recorder, recording could be done successfully:

02-11 22:01:20.820 I/OMXPlayer( 4603): LEVEL: 1 FUNCTION: SharedFdPipe_Open LINE: 39

Thank you so much for your help.

Could GMRecorder::setOutputFileFD be modified NOT to use sharedfd for gm_path

sprintf(gm_path, "sharedfd://%d:%lld:%lld",  mSharedFd, offset, length);

but to use  UdpsPipe? Should it be?

sprintf(gm_path, "udp://%d:%lld:%lld",  mSharedFd, offset, length);

[mjoa]

After modifying to use UdpsPipe in GMRecorder::setOutputFileFD

     sprintf(gm_path, "udp://%d:%lld:%lld",  mSharedFd, offset, length);

and to use udp socket fd in setOutputFile

     recorder.setOutputFile(pfd.getFileDescriptor()); //socket

crash appears as follow:
