Using direct show filters I have created a mp4 file writer with two input pin (one for audio and one for video) . I was writing audio sample received through one pin into one track and video sample received from the other pin into another track. But my video is not playing. If I connected only one pin, either Audio or Video, I can play the output file. that is if there is only one track.
I am using h264 encoder for video and mpeg4 encoder for audio. The encoders are working fine as I am able to play the audio and video separately.
I am setting the track count as 2. Is there any information to be provided in the moov box to make the video playing. Or Should we tell the decoder that which track is audio and which track is video. As we are setting those fields in track information I don't think that is important, but Why my video is not playing?
