Hi
I am trying convert a video to a different format. When I open the video there are two audio tracks, audio track 102 and 103. The audio track 102 is blank and has no audio. Audio track 103 is where the audio actually is. However when I go to convert the video it doesn't use the track with the audio on it, so I get an exported video with no sound. I tried using :audio-track=103 and :audio-track-id=103 in the more options but still there is no audio in the video. What am I doing wrong? The converted video contains both audio tracks which works well for VLC, but most of my users will be using windows media player and cannot easily select the audio track to use. How do I fix so the track with the audio on it plays automatically?

I would try --audio-track=0 (for the first track) or --audio-track=1 for the second track.

You are sure that your container (in the new format) is compatible to the audio-codec you are using ? For example audio="AAC" (and not something else such as eac3 etc.) if the container is mp4.

:no-sout-all

Unfortunately neither of the two options worked. I am using h.264 + mp3 (MP4) as my video, audio and container. I should note that I am trying to convert a .trec file from Camtasia, the audio is there in the first track it just wont make it to the default track on the exported file. I even tried using YouTube HD format to no avail. Anything else you can point me to?
