[gst-devel] problem playing h.264 file

[Carlos Molina]

I forget to paste the error output:

I tried to  create the file:

gst-launch videotestsrc ! x264enc byte-stream=true ! filesink 
location=test.264

and

gst-launch videotestsrc ! x264enc byte-stream=true ! avimux !  filesink 
location=test.264

I can play test.264 with mplayer and vlc as I previously said.. but I 
can't play with gstreamer:

gst-launch filesrc location=prueba.264 ! ffdec_h264 ! xvimagesink  

output:


gst-launch filesrc location=prueba.264 ! ffdec_h264 ! xvimagesink
