[FFmpeg-devel] [PATCH] Avoid setting a zero timebase denominator in rtpdec
Thu Jan 28 22:01:40 CET 2010
If trying to view an RTSP/RTP stream with an unsupported audio codec, the
st->codec->sample_rate field is left at zero (since it is set in
rtsp.c:145, only if a decoder was found). The zero sample rate propagates
to the st->timebase.den field at rtpdec.c:313, leading to crashes due to
division by zero when using such a time base.
The attached patch avoids the crashes by not propagating a clearly
erroneous sample rate and emits a warning message instead.
