Either of these 2 would be fine with me. > - read necessary bits directly from aac3_ac3_parse I don't like this one > > Maybe you have different ideas? For the issue you're concerned about, what you have proposed will work fine. I can only make assumptions about how these changes fit into the rest of your solution. But you seem to be on the right track. -Justin _______________________________________________ FFmpeg-soc mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-soc
