I tried converting some MP4 videos to audio-only ogg vorbis or MPEG w/
AC-3 (same as MP3?). Every file I tried resulted in a small file (only a
few kb) quickly created.
Raw audio in a WAV container worked; however, despite "no video" in the
video encoding section, the WAV files, when opened in MediaPlayer, show
the original video somehow. (I didn't even know WAV could do that.)
The MP4s in question play fine in MediaPlayer, which also plays other OGGs
just fine.

Comment (by pulkomandy):
Hi,
I noticed this issue and am currently preparing release 1.4.6 of
haikuwebkit to fix it. I don't know if the build will be done before I
leave for BeGeistert, however.
There is a recipe for the latest version of ffmpeg which works with gcc4,
but gcc2 will need to stay at 0.10 for now. I did more testing with 0.11
and there are still problems with h263 and h264 decoding. I tried
disabling various things (MMX, SSE, use of asm code, etc) but it still
crashes. Later versions are even harder to get to compile with gcc2.
There is no problem with updating the gcc4 version of ffmpeg, but the
media add-on must be made to work with either version (or maybe we need an
ffmpeg_legacy one for gcc2 and an ffmpeg one for gcc4). This allows the
gcc4 world to move on but doesn't solve our issue with legacy apps.
