Okay, so final mail (sorry!)<br>
I finally solved my problem, after some hours of research: for audio
files with pictures embedded in tags, they were indeed detected and
set into the first frame, but it was not an audioStream (of course!)
so I had to add an « else » clause to my decode loop, like this:<br>
<br>
while(av_read_frame(pFormatCtx, &avpkt) >= 0) {<br>
if(avpkt.stream_index == audioStream)<br>
(...)<br>
else<br>
av_free_packet(&avpkt); /* Dropping the damn album
cover */<br>
<br>
So, thanks very much for the help!<br>

Sorry for answering my own mail, but I've been finally able to
obtain a full trace, thanks to --disable-stripping and some
options of a PKGBUILD:<br>

It seems that I'm not freeing all of my AVFormatCtx streams
properly, but I'm using avformat_close_input(&pFormatCtx) and
avformat_free_context(pFormatCtx), am I missing something?<br>

Okay, so I compiled ffmpeg with those flags:<br>
/configure \<br>
--prefix=/usr \<br>
--shlibdir=/usr/lib \<br>
--disable-static \<br>
--enable-debug=3 \<br>
--disable-optimizations \<br>
--disable-stripping \<br>
--enable-gpl \<br>
--enable-gnutls \<br>
--enable-libass \<br>
--enable-libfdk-aac \<br>
--enable-libfreetype \<br>

--enable-libopus \<br>
--enable-libtheora \<br>

--enable-libx264 \<br>
--enable-libx265 \<br>
--enable-nonfree \<br>
--enable-shared \<br>
--enable-x11grab \<br>
And I cmake'd my program with -DCMAKE_BUILD_TYPE=Debug
-DCMAKE_C_FLAGS=-fsanitize=address, but I still only have this
debug trace:<br>

</i>First step (that is practically always sufficient)
is to find out where exactly (!) the memory was
allocated: We all know that it was inside mem.c
but the important question is what called
av_malloc().
Either use a static binary or use
--disable-stripping for a useful debug build.
