[gst-devel] My H.264 encoder cound not work well with the MP4 muxer

[Chen, Weian]

Hi All

I am developing an H.264 encoder element, and with pipeline: gst-launch videotestsrc ! myencoder ! filesink location=test.264 I can dump the test.264 data, and also I can decoder it.

But when I use pipeline: gst-launch videotestsrc ! myencoder ! mp4mux ! filesink location=test.mp4 I could not get any output, and the size of test.mp4 is 0.

Could anybody here give me some hint what's the problem in my encoder? Why my encoder could not work with the MP4 muxer?

Thanks in advanced.

BTW: I got the warning :  (gst-launch-0.10:17032): GStreamer-CRITICAL **: gst_value_set_fraction: assertion `denominator != 0' failed How to fix it?
