Using FFmpeg to encode 2pass mp4
30 juin 2016, par Erin.YangI am trying to use FFmpeg to encode my 4K mp4 file to a 2pass 265 mp4 file for the purposes of testing. I am new to video compression and hope I’m making a simple mistake that someone can correct.
All infos in command line as below :
C:\Ying\FF>C:\Ying\FF\ffmpeg.exe -y -i C:\Ying\FF\Xman-4K_50sec_3840x2160.mp4 -preset veryslow -x265-params pass=1 -vcodec hevc -b:v 15M -acodec libvo

Removing audio noise (hissing) in C++ from 16bit PCM
4 juillet 2016, par hockeyislifeI have been going through the posts of stack overflow but I am not understanding how to remove hissing sound from my audio being grabbed from the microphone.
I implemented a simple low pass filter but I must be doing something wrong.
unsigned short *buf = "audio data in PCM format";
double out_sample = 0;
int sample_size = "number of samples of audio";
for (int n = 0; n < sample_size/2; n++)
{
out_sample = (out_sample * 90 + buf[n] * 10) / 100;
buf[n] = (unsigned short) out_sample;
}The above produces really corrupt audio.
I know I need to make a low pass filter on the PCM data. Can anyone shed some light into what I am doing wrong.
Thanks in advance.

ffmpeg : How can I send a H.265 encoded stream to wowza ?
24 avril 2015, par FuzzI managed to encode H.265 to an output file like this :
ffmpeg -i test.m2ts -c:v libx265 -c:a copy output.mp4and I managed to stream a H.264 file to wowza like this :
ffmpeg -re -i sample.mp4 -vcodec libx264 -vprofile default -vprofile baseline -r 24 -g 48 -vb 150000 -strict experimental -acodec aac -ab 96000 -ar 48000 -ac 2 -f rtsp -muxdelay 0.1 rtsp://username:password@127.0.0.1:1935/ApplicationName/myStreamBut I just cant seem to stream a H.265 to a rtsp stream.
If I use the libx265 in the command above I get the error :
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or heightAny hints would be greatly appreciated.
Here is the console message with -loglevel verbose
