    ffplay http://localhost:8090/feed1.ffm

    and if i need the 7th stream i will just

    ffplay http://localhost:8090/feed7.ffm

    Please can someone help me crack this issue. FFmpeg dont have complex examples for my current situation.

  • FFMPEG Encode .avi/.mov with alpha channel to .3g2 (with alpha kept)

    20 septembre 2017, par kangaraoo

    I’d like to convert my 32bits videos (either .avi or .mov) RGB+A, to .3g2 format with FFMPEG, and keep the alpha channel.

    It should be something like that

    ffmpeg -i C:\Users\naldo\Desktop\test.avi  -vcodec libx264 -acodec libfaac -ab 48k -ar 22050 -ac 2 C:\Users\naldo\Desktop\test.alpha.3g2

    but it’s not working.
    Any ideas ?
    Thank you !
