FFmpeg adding 0.05 seconds of silence to transcoded AAC file ?
29 octobre 2015, par FTLRalphIn Java, I’m using FFmpeg to convert a WAV file to AAC with the function :
-i input.wav -ac 1 -ab 64000 -ar 22050 output.aacWhen I open these two files in Audacity, I can clearly see that the AAC file is 0.05 seconds longer, with 0.05 seconds of silence added to the beginning.
This is an issue when I try to mux this AAC file with a video file - the audio doesn’t sync up.
Is there some sort of parameter to prevent this behavior or another way to get around this issue ?
Edit - Console output while running the function :

FFMPEG gets stuck on higher resolution or frame rate [H265]
29 octobre 2015, par AnakooterI am running the following command which works perfectly on my system running Elementary OS on Intel Corei5 :
ffmpeg -f v4l2 -i /dev/video0 -c:v libx265 -x265-params crf=14:vbv-maxrate=128:vbv-bufsize=32:keyint=10:qcomp=0.5:rd=5:ctu=64:min-cu-size=8:cu-lossless=false:fast-intra=false:strong-intra-smoothing=false -tune zerolatency -s 640x480 -preset ultrafast -r 5 -pix_fmt yuv420p -an -strict experimental -f mpegts udp://239.0.0.1:5002but if I change the output size to 800x600 and or increase the frame rate from 5 to 10. After a few seconds the video gets stuck.
I have monitored the CPU usage for both the commands and it is almost identical that is between 300 to 400 percent ( since 4 cores ).
Any possible answers to mitigate the issue.
