Hello TI staff,
The follow up of our adventures with the AAC encoding inside the IPNC code.
We have found the following :
1- The AAC relies on the ALSA sound layer. When capturing sound with the ALSA layer with sampling at 48ksps we found that the code was stuck and that the CPU was taken at more than 95%. It looks like the dvsdk code dealing with Sound_alsa is bugged or else. Thus the application is stuck. The video does not start.
2- By reducing the sample rate to 8ksps, it worked a bit, the video started but is very slow.
Video size is VGA at 24fps playing smoothly when no audio is on. G711 was not properly decoded into VLC (PCM-ULAW).
Has anybody faced the same problems integrating this codec into this application in terms of performance ?
Thanks for your answers
