I am trying to overlay transparent mov or flv over an image.

I am open to both options using ffmpeg or avconv.

here is my cmd:

ffmpeg -i bg.png -i input.mov -vf \
'[0:v]setpts=PTS-STARTPTS, pad=iw*2:ih[bg]; \
[1:v]setpts=PTS-STARTPTS,scale=720:400[fg]; [bg][fg]overlay=w' -vf yadif -pix_fmt rgba     -y -vcodec qtrle -an output.mov

I Get this:

ffmpeg vs "ffmpeg"

As you can see in your console output there is a conversion occurring from rgba to yuv420p which is probably losing your alpha channel. I see no way to avoid this using avconv or the fake "ffmpeg" available in the repository (these are both from Libav; a fork of FFmpeg). See Who can tell me the difference and relation between ffmpeg, libav, and avconv?

Getting ffmpeg from FFmpeg

Now that the confusion is out of the way you should get a real ffmpeg. You can either:

If you're too lazy to do anything then just do this:

wget http://ffmpeg.gusari.org/static/32bit/ffmpeg.static.32bit.$(date +"%F").tar.gz
tar xzvf ffmpeg.static.32bit.$(date +"%F").tar.gz

Note when you execute the binary you just downloaded don't forget to prefix it with ./, as in ./ffmpeg (or use the full path) or you may run the fake "ffmpeg" instead.

filtering

You can use the option format=rgb in the overlay video filter; otherwise the default of yuv420p will be used:

ffmpeg -y -i bg.png -i input.mov -filter_complex \
"[0:v]setpts=PTS-STARTPTS, pad=iw*2:ih[bg]; \
 [1:v]yadif,setpts=PTS-STARTPTS,scale=720:-1,crop=iw:400[fg]; \
 [bg][fg]overlay=w[out]" \
-map "[out]" -vcodec qtrle output.mov

  • Use -filter_complex instead of -vf for complex filtergraphs.

  • All filtering should occur within one filtergraph, so you should move yadif to your other filters. This gives you the advantage of controlling exactly when yadif should be used.

  • 1280x720 will scale to 720x405 while keeping aspect. The -1 in the scale example automatically determines the value 405. I then added crop to remove the extra 5 pixels to avoid the slight squishing that will occur if you simply just scale to a specific size.

  • You can also probably then remove -pix_fmt rgba now that everything will remain within RGB. If you find that you still need it then use the format video filter instead, such as format=rgba, so you can control exactly when the filter should be implemented.

  • I prefer to explicitly name the output link label in the filtergraph (as [out] in this example, but you can use almost any arbitrary name) and then map it so the default behavior does not give any surprises.

  • -y is a global option which should be declared before input options.
