Hi all,
Currently I am working with TI Davinci processor, and I build a gstreamer pipeline for video streaming as follows:
v4l2src->capsfilter->tee->queue->resizer->h264encoder->rtph264pay->udpsink
->queue->resizer->mjpegencoder->filesink
It is just a brief outline, and it works ok.
Now I want to change the resolution from D1->CIF on the fly, currently, I do the following:
1. get the src pad of queue
2. block the pad
3. change the properties of resizer and the encoder.
4. unblock the pad
but after that, the pipeline stops working. I am new to gstreamer, and wonder if anyone could give me some suggestion.
regards,
Rafael
