Cannot save H.264 bitstream in QuickTime (qtmux) file, error "failed to determine the time to mux"
Locked

Following is the pipeline I used:
gst-launch -e v4l2src ! ffmpegcolorspace ! x264enc ! qtmux ! filesink location=a.mov The output from gst-launch is: ERROR: from element /GstPipeline:pipeline0/GstQTMux:qtmux0: Could not multiplex stream. Additional debug info: gstqtmux.c(1107): gst_qt_mux_add_buffer (): /GstPipeline:pipeline0/GstQTMux:qtmux0: Failed to determine time to mux. Execution ended after 416709785 ns. I also tried the following 2 pipelines and both of them are working fine. gst-launch -e v4l2src ! ffmpegcolorspace ! qtmux ! filesink location=a.mov gst-launch filesrc location=Videos/g.mov ! decodebin ! ffmpegcolorspace ! x264enc ! qtmux ! filesink location=a.mov I have tried both webcam and TV capture card as the capture device, but got the same result. Has anyone seen similar problem before? I found one post reporting the same problem, but there was no followup. http://www.nabble.com/rtsp---h264---mp4mux-td23866919.html#a23937937 Thanks! Yiliang |

This issue has already been fixed in current git (it was a v4l2src issue).
You can backport the change (commit 72af90ae31907964b31c368164ec17d0f72aa7bf), upgrade to the git version or wait a new -good release come out. Maybe adding a videorate after v4l2src will also make it work.

Hi Thiago,
Thanks for the quick help. I tried videorate, and it worked. I will test the newer good-plugin later. Yiliang On Tue, Oct 20, 2009 at 10:38 AM, thiagoss <[hidden email]> wrote:
