[gst-devel] question about converting a 3gp file

[Stefan Kost]

Hi,

the pipeline mostly looks good. Can you try "demuxer.audio_%d" instead of
"demuxer.audio_%02d". Could you maybe also try this variant:

gst-launch -m filesrc location=/jill.3gp ! qtdemux name=demuxer \
ffmux_3gp name=mux ! filesink location=/jill3.3gp \
demuxer.video_%d ! ffdec_h263 ! ffenc_h263 bitrate=50000 rtp-payload-size=500
gop-size=3 me-method=4 ! mux.video_%d \
demuxer.audio_%d !  mux.audio_%d

If none works please file a bug?
