It corresponds to about two frames of the stream, so it seems to me that the avdec_h264 does some buffering.</div><div id="yui_3_16_0_ym19_1_1499726396762_5350"><br id="yui_3_16_0_ym19_1_1499726396762_5351"></div><div dir="ltr" id="yui_3_16_0_ym19_1_1499726396762_5352">Is there a way to reduce this latency and/or reduce/avoid buffering in the decoder?</div></div></body></html>
