Hello,
After my performance troubles with Theora I wanted to investigate the
performance of ffmpeg's mpeg4 codec. Cpu-usage was lower. Still the A/V
was out of sink due to avimux.
I can't get it to work with ffmux_mp4 and ffdemux_mov_mp4_m4a_3gp_3g2
gst-launch-0.8 -v sinesrc ! faac profile=1 ! ffmux_mp4 ! testsink !
filesink location="blaatschaap.mp4"
Then I try something like:
gst-launch-0.8 -v filesrc location="blaatschaap.mp4" !
ffdemux_mov_mp4_m4a_3gp_3g2 name=demux demux.audio_0 ! { faad ! alsasink }
Which does initialize the filesrc/ffdemux right (I guess) but fails to
link the audio. What is the correct way to do this with gst-launch?
Playbin doesn't work directly :(
Thanks in advance,
Stefan de Konink
ps. gst-launch-0.8 -v sinesrc ! faac profile=1 ! faad ! alsasink (does
work for me)
