Really need help. Does anyone have an idea? <div class="gmail_quote">2011/3/7 hilal ergun <<a href="mailto:hilalergunn@gmail.com">hilalergunn@gmail.com</a>> <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Hi, I am trying to mux two or more mpeg4 videos into mpegts. My pipeline; ------- filesrc location=test1.avi ! ffdemux_avi ! gst-launch -----------> mpegtsmux ! filesink location=test.mpts -------- filesrc location=test2.avi ! ffdemux_avi ! This pipeline works fine, then "ffmpeg -i test.mpts" shows: Input #0, mpegts, from 'test.mpts': Duration: 00:03:00.00, start: 0.040000, bitrate: 3832 kb/s Program 1 Stream #0.0[0x41]: Video: mpeg4, yuv420p, 592x238 [PAR 147:148 DAR 42:17], 25 fps, 25 tbr, 90k tbn, 25 tbc Stream #0.1[0x40]: Video: mpeg4, yuv420p, 624x336 [PAR 77:78 DAR 11:6], 1199 tbr, 90k tbn, 1199 tbc But i don't want this. I want these streams into 2 different programs.So I write a simple program and set 'prog-map' parameter. Then new ffmpeg output becomes: Input #0, mpegts, from 'test.mpts': Duration: 00:03:00.00, start: 0.040000, bitrate: 3832 kb/s Program 2 Program 1 Stream #0.0[0x41]: Video: mpeg4, yuv420p, 592x238 [PAR 147:148 DAR 42:17], 25 fps, 25 tbr, 90k tbn, 25 tbc No Program Stream #0.1[0x40]: Video: mpeg4, yuv420p, 624x336 [PAR 77:78 DAR 11:6], 1199 tbr, 90k tbn, 1199 tbc As you can see one of the streams is not associated with any program. Either I'm doing something or there is some problem with mpegtsmux. I'm using gst-plugins-bad is 0.10.19 and Gstreamer 0.10.30. I tried to debug mpegtsmux code and I can see that 'ts_data->prog_id' is properly set in the code. However, new streams don't seem correct. Does anybody have any idea about what may be wrong? Thanks. </blockquote></div>
