All I got are access unit delimiter RBSP's. An acces unit delimiter RBSP is something like 000000010910 for the I frame, and 000000010030 for the non-I frame.<br> <br>Since the AU delimiter has the same timestamp as the following NAL, I was wondering whether that was a problem. And indeed it was. In the function compute_pkt_fields2() in file: /gst-ffmpeg-0.10.9/gst-libs/ext/ffmpeg/libavformat/utils.c<br> <br>I changed the following line to allow two consecutive packets have same time stamp:<br><br> <p style="margin:0px;text-indent:0px">#if 1</p> <p style="margin:0px;text-indent:0px"> if(st->cur_dts && st->cur_dts != AV_NOPTS_VALUE && st->cur_dts > pkt->dts){</p> <p style="margin:0px;text-indent:0px">#else</p> <p style="margin:0px;text-indent:0px"> if(st->cur_dts && st->cur_dts != AV_NOPTS_VALUE && st->cur_dts >= pkt->dts){</p> <p style="margin:0px;text-indent:0px">#endif</p> <p style="margin:0px;text-indent:0px"></p><br>Now I can capture video correctly. I am wondering if anyone working on ffmpeg can verify whether this fix is a valid solution. Maybe I should post a separate message on ffmux_mp4.<br> <br>However, this does not solve my problem. I still need to make qtmux work since it supports the audio codec which ffmux_mp4 does not support.<br><br>Thanks,<br><font color="#888888">Yiliang</font><div><div></div><div class="h5"> <br><br><div class="gmail_quote">On Tue, Nov 24, 2009 at 12:05 AM, florian iragne <span dir="ltr"><<a href="mailto:florian.iragne@viewsurf.com" target="_blank">florian.iragne@viewsurf.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="border-left:1px solid rgb(204, 204, 204);margin:0pt 0pt 0pt 0.8ex;padding-left:1ex"> Hi,<br> <br> Yiliang Bao a écrit :<br> <div>> I got this error:<br> ><br> > gstqtmux.c(1347): gst_qt_mux_add_buffer ():<br> > /GstPipeline:pipeline0/GstQTMux:qtmux0:<br> > Failed to determine time to mux.<br> <br> </div>i got the same error and have had no success using qtmux or mp4mux.<br></blockquote></div></div></div></blockquote><div><br></div><div>Some fixes were pushed to qtmux/mp4mux for improving timestamps and durations handling yesterday.
