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.
