Hi , Santos,
Now I believe bug lies in the plugin " h264parse " , by changing the testing
pipeline.
At first , my pipeline is like :
gst-launch -v --gst-debug-level=$dbg \
filesrc location=davincieffect_ntsc.264 \
! h264parse ! mux. \
filesrc location=davincieffect.aac ! aacparse ! mux. \
mpegtsmux name=mux \
! filesink location=out_264_for_6446.ts
Then I changed the testing pipeline :
The first one :
gst-launch -v --gst-debug-level=$dbg \
videotestsrc ! video/x-raw-yuv,width=176,height=144,framerate=10/1
! x264enc \
! mux. \
filesrc location=davincieffect.aac ! aacparse ! mux. \
mpegtsmux name=mux \
! filesink location=out_264_for_6446.ts
The second one :
gst-launch -v --gst-debug-level=$dbg \
filesrc location=test.mov ! qtdemux name=qtdemux demux.video_00 !
queue \
! mux. \
filesrc location=davincieffect.aac ! aacparse ! mux. \
mpegtsmux name=mux \
! filesink location=out_264_for_6446.ts
Both the pipelines works well .And the ts file can be decoded correctlly by
vlc media player.
So maybe a bug in h264parse.
Hope these to be helpful...
FYI: you can take a look at this post :
