> Assuming "alpha codec" means that the encoder can really save
transparency information in the mpeg2 video stream, could you try to
encode a file that actually contains transparency?

http://samples.ffmpeg.org/FLV/flash_with_alpha

I would like to generate a sample with alpha, but I do not match the specs
for example for Adobe Premiere CS6 which I could use for it:

premiere-pro.html#Adobe%20Premiere%20Pro%20CS6%20system%20requirements
If you meet then maybe you can use this instruction to generate a file:
