Description changed by John Sterling:
Old description:
> For static Linux builds of ffmpeg versions 6.0 and later, a segfault
> occurs when processing an HTTP input file with a seek (possibly related
> to range requests or multiple requests against a URL?). For example, when
> capturing a single frame at 30 seconds as an image from an MP4 URL. If
> requesting the first frame, or if requesting from an HTTP server which
> does not support byte-range requests, the segfault does not occur.
>
> I have reproduced this in 6.0.1, 6.1, and git-master, both from source
> and using builds from [https://www.johnvansickle.com/ffmpeg/] but cannot
> reproduce with 5.1.4. Building from source with a plain ./configure (not
> including --extra-ldexeflags="-static") does not exhibit the behavior.
>
> Here is a Dockerfile which produces a build from git-master:
> {{{
> FROM debian:bullseye
> RUN apt update && apt install -y --no-install-recommends \
> autoconf \
> automake \
> build-essential \

> RUN cd ffmpeg && \
> ./configure --extra-ldexeflags="-static" && \
> make -j8 &&
> }}}
>
> And running the resulting container, here is an example command causing
> the crash:

New description:
For static Linux builds of ffmpeg versions 6.0 and later, a segfault
occurs when processing an HTTP input file with a seek (possibly related to
range requests or multiple requests against a URL?). For example, when
capturing a single frame at 30 seconds as an image from an MP4 URL. If
requesting the first frame, or if requesting from an HTTP server which
does not support byte-range requests, the segfault does not occur.
I have reproduced this in 6.0.1, 6.1, and git-master, both from source and
using builds from [https://www.johnvansickle.com/ffmpeg/] but cannot
reproduce with 5.1.4. Building from source with a plain ./configure (not
including --extra-ldexeflags="-static") does not exhibit the behavior.
Here is a Dockerfile which produces a build from git-master:
{{{
FROM debian:bullseye
RUN apt update && apt install -y --no-install-recommends \
autoconf \
automake \
build-essential \
ca-certificates \
cmake \
gdb \
git \
yasm
RUN update-ca-certificates
RUN git clone --depth=1 https://git.ffmpeg.org/ffmpeg.git
RUN cd ffmpeg && \
./configure --extra-ldexeflags="-static" && \
make -j8
}}}
And running the resulting container, here is an example command causing
the crash:
{{{
