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 — Thu, 12 Feb 2015 13:21:26 GMT

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

02-11 22:01:20.820 I/OMXPlayer( 4603): SFD open sharedfd://28:0:0

02-11 22:01:20.830 I/OMXPlayer( 4603): start recorder.

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);

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:
