Public bug reported:

OpenShot 1.4.0
Installed from OpenShot PPA
Ubuntu 11.10 (completely up to date)
FFmpeg compiled from source, version 5:201112071053-git-1

SUMMARY:

An MP3 that was originally encoded with pcm_s16le in FFmpeg plays in the
preview of the OpenShot project, but when OpenShot exports a video using
the ac3 audio codec, the audio from the pcm_s16le encoded MP3 fails to
carry over into the newly exported video.

However, when exporting to MOV using pcm_s16le, the audio is re-encoded
without a problem.

WHAT HAPPENED:

I exported a .mov with the following settings:

Video Format: mov
Video Codec: libx264
Bit Rate: 5Mb/s

Audio Codec: ac3
Sample Rate: 44100
No. of Channels: 2
Bit Rate : 128 kb/s

And the video came out fine, but there was NO AUDIO.

WHAT HAPPENED NEXT:

I exported exactly the same project as .mov with these settings:

Video Format: mov
Video Codec: libx264
Bit Rate: 5Mb/s

Audio Codec: pcm_s16le
Sample Rate: 44100
No. of Channels: 2
Bit Rate : 128 kb/s

And the AUDIO WAS OK.

POSSIBLY RELEVANT:

When I recorded the original webcam + audio MKV in ffmpeg, the audio
codec used was pcm_s16le.
