Hi all, i recently interated live into my application as was amazed how simple and robust it is. now i want to stream live-generated images over a LAN with maximal quality and minimal latency. I have a RGBA image source, and i have an ffmpeg encoder to compress the video so far.
Right now i can stream mpeg-2 with ffmpeg settings float video_qscale = 1.0; vcodec->gop_size = 0; vcodec->flags |= CODEC_FLAG_QSCALE; v_codec->global_quality = _video_st->quality = FF_QP2LAMBDA * video_qscale; this should create only intraframes. As a receiver i use VLC 1.05 with reduced cache ( 200 ms ) My results are: very good image quality but non-fluent playback. Every 1-2 seconds, there is a stutter/hang of 3-6 frames even when streaming from app to app at the same machine. Increasing VLC cache time does not change behaviour. Is it possible that there are non-continous timestamps somewhere? What would be the best strategy to create the best possible videostream? Network bandwidth is not so much an issue - a gigabit connection is available. 1) what is the best codec ( quality, encoding speed ) 2) best codec options ( only i-frames ) 3) best receiver - can i get advantages over eg. VLC if i re-implement the receiver on my own?
