DietPi-Software | FFmpeg: Enable HW encoding (RPi)

[Fourdee]

ADMIN EDIT

Please help testing the new RPi packages: #869 (comment)

G_AGI --reinstall ffmpeg

---

Requires binary compiles:
https://github.com/Fourdee/DietPi/issues/475#issuecomment-292734524

Programs such as Emby, should benefit vastly from this.

[Fourdee]

RPi devices (all distros) will now install our compiled FFmpeg binary with OpenMAX enabled.

[Fourdee]

Tests:

• 🈯️ ARMv6
• 🈯️ ARMv7
• 🈯️ Stretch

Emby + OpenMAX enabled in transcode options:

• 1080p, no stuttering 🥂

Needs recompile with prefix --prefix=/usr, else /usr/local/lib and export LD_LIBARY_PATH required.

[WolfganP]

@Fourdee could you please share how can we install this custom version for testing? Thx in advance.

[Fourdee]

@WolfganP
Once re-compiled (should be done tomorrow), testing branch install can be used. I'll let you know when its ready + instructions.

[Fourdee]

@WolfganP

Ready for testing, you could install the updated FFmpeg binaries with simply:

INSTALL_URL_ADDRESS='http://dietpi.com/downloads/binaries/rpi/ffmpeg_rpi.7z'
wget "$INSTALL_URL_ADDRESS" -O package.7z
7z x -y package.7z -offmpeg_rpi
dpkg -i ffmpeg_rpi/*.deb
rm -R ffmpeg_rpi
rm package.7z

[Fourdee]

Marking as completed.

@WolfganP
If you run any tests, please let me know if any issues.

[WolfganP]

Will do @Fourdee

[MichaIng]

@Fourdee
Maybe it's time to compile a new version? Even Debian Stretch repo is some subversions further via security patches: https://packages.debian.org/stretch/ffmpeg

V4.0.2 available on Buster repo (for testing) and GitHub sources of course: https://github.com/FFmpeg/FFmpeg/releases

[Fourdee]

@MichaIng

Yep, agree.

Heres the old compile code I used, here for reference. I'll take a look at this when I can:

I guess Debian armhf packages do not (fully) support RPi?
E.g. https://packages.debian.org/buster/libx265-165

[MichaIng]

The ffmpeg package from archive.raspberrypi.org repo got HW acceleration:

ffmpeg (7:3.2.12-1~deb9u1+rpt1) stretch; urgency=medium

  [ Dave Stevenson ]
  * avcodec/omx: Fix handling of fragmented buffers
  [ Serge Schneider ]
  * Add libraspberrypi0 dependency
  * Set --arch=armhf
  [ Arindam Chaudhuri ]
  * Enable Raspberry Pi HW acceleration

Same for the package from Buster branch:

ffmpeg (7:4.1-1+rpt1) buster; urgency=medium

  [ Dave Stevenson ]
  * avcodec/omx: Fix handling of fragmented buffers
  [ Serge Schneider ]
  * Add libraspberrypi0 dependency
  * Set --arch=armhf
  [ Arindam Chaudhuri ]
  * Enable Raspberry Pi HW acceleration

 -- Serge Schneider <[email protected]>  Wed, 06 Feb 2019 14:17:15 +0000

These packages are preferred by APT over the ones from Raspbian repo (identical to Debian repo), so I suggest we revert to APT install on RPi as well.

However some quick test would be great, including AAC/x264/x265.

[MichaIng]

Included and merged: #2875

Actually since the repo version is newer, an APT upgrade must have upgraded the package already (present since end of January), so it's just to avoid installing our own compiled package first.
