Hello, so far I know, FFmpeg doesn't support sending m2ts packets, but I'm not sure. You have to look at the possible output formats to find this out. But if you do the RTP way, which I described, you can add this 4 Byte by your self after read the packet from the local video file, before send then to RTP. But I don't know how the format of this 4 Byte is about. > > the point 4. Do you use it in http_prepare_data?? > No, because I don't use the ffserver code in my project. To use my code for sending a mpegts file 'as is' to a client, you have to modify my code, because it handles with raw-pictures. It first encode a picture to MPEG-2 (encode_video()) and then send it as a mpeg-ts rtp stream. For you, is enough to open the file an read the ts-paket from it and then write it to the rtp output. > tspkt.size = len; > tspkt.data = destbuff; > > //write to output , not sure if _interleaved_ is the right call > av_interleaved_write_frame(rtpcontext, &tspkt); > av_free(destbuff); Steffen _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
