I see that the last few frames of the video is chopped away, meaning that the length of the video is less than the recorded video. My video input is from webcam. I keep feeding data by grabbing samples from directshow. This is my encoding code, nothing special:
[cpp]status = m_mp4Muxer.LockBuffer(&m_outVideoData, m_mp4Muxer.GetTrackIndex(UMC :: VIDEO_TRACK));
if (status == UMC :: UMC_OK) {
status = m_VideoEncoder.GetFrame(&m_inVideoData, &m_outVideoData);
if (status == UMC :: UMC_OK) {
status = m_mp4Muxer.UnlockBuffer(&m_outVideoData,
m_mp4Muxer.GetTrackIndex(UMC :: VIDEO_TRACK));
}
}[/cpp] The status variable always prints 0 meaning success. This is in the debug mode. The last few frames are gone many a time.
Of course, in Release mode the video file is un-playable.
So, How do I ensure I wait for all frames. Especially when status returns success always.
I checked the video file using mediainfo and it says that the video is encoded using High profile. How is that possible? I use defaults. Shouldn't the default be Main profile:
This is the output from mediainfo:

Note that in the end, when the user presses stop, I do mark end of stream
[cpp]m_mp4Muxer.PutEndOfStream(m_mp4Muxer.GetTrackIndex(UMC :: VIDEO_TRACK));[/cpp]
