Issue with 'avenc_aac' encoder while combining video && audio streams

I want to combine audio and video streams and save the resulting stream into a file. Following below is shown a command line I try to use.




gst-launch-1.0 avfvideosrc -e device-index=0 !
video/x-raw,width=720,height=576 ! tee name=t t. ! queue !
osxvideosink sync=false t. ! videoconvert ! vtenc_h264_hw
realtime=true max-keyframe-interval=5 ! queue ! mux. osxaudiosrc
device=0 ! audioconvert ! avenc_aac ! queue ! mux. mp4mux name=mux !
filesink location='output.mp4'




gst-launch shows an error:




illegal instruction: 4




The problem here is with avenc_aac encoder.
What parameters should be added to avenc_aac encoder to get working command line?



May be it is possible to use another one encoder for such purposes?

What are your system specs? Perhaps the encoder requires some SSE4/AVX instructions your CPU does not support. An alternative AAC encoder is voaacenc.

  • Maybe it is something in your base GStreamer installation. Maybe you need to build it yourself for you exact instruction set for that (kinda old) machine.

Why https connections are so slow when debugging (stepping over) in Java?

Image
up vote 0 down vote favorite I'm trying to debug some problems with my Java code, which establishes a http/https connection. I'm wondering why the connection gets ridiculously slow (more than one minute for downloading a small web page) when debugging, even when stepping-over the method which does the network work. And if there is some remedy. Below I post an example (you can change https: to http: , and try debugging this from Eclipse pressing F11 - for stepping, place a breakpoint in the first main() statement, and press F6 when it pauses there. My results (time in milliseconds) : conn time total time http (not stepping) 60 350 http (stepping over) 1100 1500 https (not stepping) 570 1300 https (stepping over) 21000 83000
