Difference in these two pipelines

[Dylan Broome]

Hi all,

Im trying to decode a video/subtitle stream, overlay the subtitles on the
video via textoverlay and save the resulting video.

(using gstreamer 1.2.0)

I figured this should be the pipeline :

gst-launch-1.0 filesrc location=rear_2014-04-02_0.mkv ! matroskademux
name=demux ! h264parse ! imxvpudec ! textoverlay name=overlay !
imxvpuenc_h264 bitrate=1024 ! h264parse ! matroskamux ! filesink
location=debug.mkv  demux. ! katedec ! overlay.

This does not convert the subtitles properly. The following pipeline does
work :

gst-launch-1.0 filesrc location=rear_2014-04-02_0.mkv ! matroskademux
name=demux ! h264parse ! imxvpudec ! textoverlay name=overlay !
imxvpuenc_h264 bitrate=1024 ! h264parse ! matroskamux ! filesink
location=debug.mkv filesrc location=rear_2014-04-02_0.mkv ! matroskademux !
katedec ! overlay.

As you can see I use 2 filesrcs and 2 matroskademuxs. What am I doing wrong
in the first pipeline? Is this possible to do with only 1 filesrc/demux ?

Regards,
Dylan
