Hello, When I resample an audio file to the AV_SAMPLE_FMT_DBLP sample format with libswresample, I get some values out of the interval -1, 1. It happens when I resample from 44100 to 48000 for example. I tried to use the rematrix_maxval option like this :
SwrContext *ctx = swr_alloc(); ... av_opt_set_double(ctx, "rematrix_maxval", 1, 0); swr_init(ctx); but it have no effect. Does the way I use it are supposed to guarantee values between -1 and 1 or did I not understand its purpose? I can solve the problem by setting the rematrix_volume option to 0.96 but I'm not sure it will work in all cases. I wonder if being in 32 bits can be the cause of the problem. Thank you in advance for your attention. _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
