[FFmpeg-user] The audio does not get replaced when merging flv with wav

I have two flv videos, both of them have an audio track. I have two seperate .wav files. I can replace the audio on the first flv file with either of the wav files, but I cannot replace the audio on the second flv with either audio. The command line is... ffmpeg -i video2.flv -i audio2.wav

I am trying to convert .flv files to mp4 files. In some cases I get the sound but in most I do not. I have tried different command line options based some other posts on the internet, but none of them have worked. My command line is... ffmpeg -i in.flv -ar 22050 -c:v libx264 -strict -2 -c:a aac

[FFmpeg-user] When merging an image with audio the resulting mp4 has a black screen

I am in the process of converting an existing application to the latest version of ffmpeg. When I merge an jpg and wav file to create an mp4 I get a black screen. The command line is... ffmpeg -loop 1 -y -i image3.jpg -i audio2.wav -vf scale=400:300 -acodec libvo_aacenc -vcodec libx264 -shortest
