Hi Steaphano, OK I read doc and play with ffmpeg -vf parameters and I understand padding, scale filters etc ...
I read the ffplay code in #if CONFIG_AVFILTER My problem in the ffplay code is to have two input ie two buffers. I have two streams one in h264 and the other one in Mpeg2, each of them have VITC codes ( Time Stamp). The h264 is delayed of 3 seconds and I need to synchronize them by this VITC (ie delete all the buffer with old Time stamp) If I use AVFIlter I will have to write a special filter I will try before to use swscale to convert in RGB and use SDL blit Surface to see if 4xIntel Xeon will be fast enough Your comments are welcome Thanks again for your help Gilles 2011/2/15 Stefano Sabatini <[email protected]> > On date Tuesday 2011-02-15 18:52:33 +0100, Gilles Maire encoded: > > > > > > > > > the second can be achieved with padding+overlay (but would be best > > > achieved with a "compose" filter). > > > > Does compose filter exist ? > > No. > > > and where can I find padding filter ? > > Did you check the docs? > _______________________________________________ > libav-user mailing list > [email protected] > https://lists.mplayerhq.hu/mailman/listinfo/libav-user > _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
