visual c++ - Noise occurs while encoding audio from Microphone and latency in video streaming using IMFSourceReader -

i'm developing application capture.mp4 file (video(usb camera)and audio(any microphone) )during video streaming using sourcereader.

my code returning success api's , able save video. i'm facing below 3 issues.

1. after 10secs of recording , fps goes 0 , resume 1fps(note: saving video 1080p 60fps). fps not resuming 60fps.
2. while playing recorded file, noise audio playing whole file. recorded audio file not playing.
3. to stop record, i'm using sinkwriter finalize method. application not responding call method , method taking time release it(time taken release ~3-5mins).

please find code in following dropbox link: https://www.dropbox.com/s/eddwdc1z9wsoh04/videorecord.txt?dl=0

without problem, i'm able capture audio , video using capture engine technique technique supports windows 8. application has support windows 7.

please let me know whether missing configure audio , video? me solve issue.

thanks in advance

i see few mistakes. first, call readsample mf_source_reader_first_video_stream. read video samples. should call readsample (first time , inside onreadsample) mf_source_reader_any_stream instead, in order make read both video , audio samples.

second, following 2 lines wrong:

hr = m_pwriter->writesample(0, psample); hr = m_pwriter->writesample(1, psample); 

you should call writesample corresponding stream index according dwstreamindex value in onreadsample. example in case:

if(dwstreamindex == 0)     hr = m_pwriter->writesample(m_dwvideostreamindex, psample); else if(dwstreamindex == 1)     hr = m_pwriter->writesample(m_dwaudiostreamindex, psample);
