mplayer-1.5 FTBFS with binutils-2.41

[Joe Locash]

The patch for ffmpeg-6.0 can also be used here:

patch -Np1 -d ffmpeg/ -i <path to>/ffmpeg-6.0_binutils-2.41.patch

I've switched to using mpv which is based on mplayer but uses the system ffmpeg.

Confirmed, the command works (in terms of applying as well as successful compilation of mplayer)

mplayer is an "end" package. That is, nothing depends on it. I'm hoping upstream will make a new release soon. We can delay fixing this until just before we release blfs-12.0.

[Bruce Dubbs]

I took a closer look at this. Indeed the patch works. Unfortunately I did not see anything on the mplayer mailing lists about this. I checked to see if we could use system ffmpeg, but nothing about that was obvious in configure --help.

The current release was from February 2022 so I'm not hopeful for a release any time soon. I'll add the patch to the book.

[Bruce Dubbs]

There was also a missing upstream_ffmpg6_fixes patch. Both patches were added.

Fixed at commit 2415b9446dfd02c1435e66c821d2904954991a22

The option to build mplayer against the system installed ffmpeg is in the book but doesn't have a good description. It's --disable-ffmpeg_a

configure --help gives:

  --disable-ffmpeg_a        disable static FFmpeg [autodetect]
  --disable-ffmpeg_so       disable shared FFmpeg [autodetect]

The book says:

--disable-ffmpeg_a: You can use this option if you have installed a version of ffmpeg prior to ffmpeg-6.0. This version of MPlayer is incompatible with the latest version of ffmpeg. MPlayer does include a copy of the FFmpeg source and without this option it will statically compile the included version of FFmpeg into itself.

Since the book does use ffmpeg-6, that option is not appropriate for us.

Why was my previous comment edited?

But to address: "Since the book does use ffmpeg-6, that option is not appropriate for us."

That is incorrect. If you do not pass --disable-ffmeg_a it will build and use the bundled ffmpeg version. Like I said, the description of --disable-ffmpeg_a in the book isn't that good.

Because I inadvertently selected edit instead of reply. Sorry.

That's right. We are applying the valid ffmpeg6 fixes to the version in the book. AFAIK the full ffmpeg-6 still does not work with mplayer, but the instructions in the book now do. How would you change the description in the book?

That's what i figured.

mplayer works fine with upstream ffmpeg6. The latest ffmpeg changes for mplayer are always in svn.

The instructions in the book work because you don't pass --disable_ffmpeg_a to configure in the book. By not passing it, you're building against the bundled ffmpeg which is v5.1.

[Bruce Dubbs]

I'll try with system ffmpeg6. Does it just need the ffmpeg-6.0-binutils_2.41-1.patch?

[Bruce Dubbs]

Never mind. I'll update the book.

The package builds but

$ mplayer big_buck_bunny.mp4

Playing big_buck_bunny.mp4.
libavformat version 60.3.100 (external)
Mismatching header version 59.17.102
libavformat file format detected.

if input is local or a network protocol, buffers and access patterns cannot be
configured optimally without knowing the protocol

but with the instructions in the book it plays fine.
