ok, well making ltp_state float fixed that one, but the fate latm sample still turns to static after playing ok for a few seconds. al_sbr_cm_48_2.mp4 does the same after about 15 seconds. it could be SBR? or TNS? Something along the way is assuming the float samples are scaled to 16-bit range, but I can't find where that is... -Justin _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
