Hi,
I am implementing DM365 TVP5158 -> CCDC-> Capture-> Display. Capture resolution is 720 x 576 PAL.
I am running it on a message thread so that I can add additional tasks later.
Currently I have modified the working IPIPE in accordance to my requirement. My capture and display thread uses only AVSERVER_bufputFull and AVSEREVER_bufGet Empty functions.
AVSERVER_bufGetNextTskInfo() is modified in the following way.
int AVSERVER_bufGetNextTskInfo(int tskId, int streamId, OSA_BufHndl **pBufHndl, OSA_TskHndl **pTskHndl)
{
VIDEO_CaptureStream *pCaptureStream=NULL;
VIDEO_EncodeStream *pEncodeStream=NULL;
VIDEO_DisplayStream *pDisplayStream=NULL;
int nextTskId;
*pTskHndl=NULL;
*pBufHndl=NULL;
if(streamId<0 || streamId >= AVSERVER_MAX_STREAMS) {
OSA_ERROR("Incorrect streamId (%d)\n", streamId);
return OSA_EFAIL;
}
/* if(tskId <=VIDEO_TSK_NONE || tskId >= VIDEO_TSK_STREAM) {
OSA_ERROR("Incorrect tskId (%d)\n", tskId);
return OSA_EFAIL;
}*/
if(tskId <= VIDEO_TSK_RESIZE) {
pCaptureStream = &gVIDEO_ctrl.captureStream[streamId];
pDisplayStream = &gVIDEO_ctrl.displayStream;
nextTskId = VIDEO_TSK_NONE;
if(tskId==VIDEO_TSK_CAPTURE) {
nextTskId = pCaptureStream->captureNextTsk;
}
if(nextTskId==VIDEO_TSK_NONE) {
*pBufHndl= &gVIDEO_ctrl.displayStream.bufDisplayIn;
*pTskHndl = &gVIDEO_ctrl.displayTsk;
//*pBufHndl = &pDisplayStream->bufDisplayIn;
//*pTskHndl = &pCaptureStream->displayCopyTsk;
// return OSA_EFAIL;
}
}
When I run the code I see that buffers not being allocated for CAPTURE OUT which is mainly because of AVSERVER_getemptybuf() function. Could anyone please look into it and let me know if anything more needs to be changed ? or some patch which does just capture and display but in threads. I have tried modifying for a real long time and stuck here right now.
Also, I was just checking of at least capture happens and to validate it I tried opening dumping the frame into a file using fwrite but it says " Read only filesystem". I have changed the folder permissions also but in vain!
Please anyone out there help me with this or let me know if I'm missing something!
Attached is the application log!
