Package: libspeexdsp1 Version: 1.2~rc1-6 Severity: normal Tags: patch Hi,
I noticed a quite strange behavior of speex when I resample a large input buffer (so underbuffering is not a problem). It stops during the call even when neither the number of requested out_len nor the number of provided input samples was reached. http://www.speex.org/docs/manual/speex-manual/node7.html says something completely different: "Unless an error occurs, either all input samples will be read or all output samples will be written to (or both)." I've attached a test program that should show the problem. The input buffer is usually a lot larger, but I reduced it to keep the source file small. I get following output form the test program: "Resampling stopped during processing. 2 samples missing in output and 100 samples from input weren't used". The example can be compiled using: $ unxz speex_resampler_missing_outputsamples.c.xz $ gcc speex_resampler_missing_outputsamples.c \ `pkg-config --cflags --libs speexdsp` \ -o speex_resampler_missing_outputsamples A patch to fix this problem is attached. --- System information. --- Architecture: amd64 Kernel: Linux 3.2.0-3-amd64 Debian Release: wheezy/sid 500 unstable www.deb-multimedia.org 500 unstable http.debian.net 500 testing http.debian.net 1 experimental www.deb-multimedia.org 1 experimental http.debian.net --- Package information. --- Depends (Version) | Installed ======================-+-=========== libc6 (>= 2.3.4) | Package's Recommends field is empty.
