FAILED: libffmpeg.so libffmpeg.so.TOC

[SeduardoIA0]

I am trying to create my own version of chromium with HEVC support, on ubuntu, and I am failing to create it. I add the steps that I am following. Thank you in advance for the help.

System:

Steps: cd /home/eduardo/2023/chrome/ git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git export PATH="$PATH:/home/eduardo/2023/chrome/depot_tools" mkdir chromium && cd chromium fetch --nohooks --no-history chromium cd src ./build/install-build-deps.sh gclient runhooks gn gen out/Default

autoninja -C out/Default chrome

Looks like this section (https://github.com/StaZhu/enable-chromium-hevc-hardware-decoding/blob/d0b8d2d4cb1b5ff3cf0fe95da200ad686db76294/add-hevc-ffmpeg-decoder-parser.patch#L3126) is not included in the dependency.

Looks like maybe because you are using wrong gn args to build the chromium, can you share your gn args?

[StaZhu]

Keep in mind that this section is important:

If you are using Mac + want to build x64 arch (target_cpu to x86 , arm64 , arm also available) + want to add CDM support, then run gn gen out/Release64 --args="is_component_build = false is_official_build = true is_debug = false ffmpeg_branding = \"Chrome\" target_cpu = \"x64\" proprietary_codecs = true media_use_ffmpeg = true enable_widevine = true bundle_widevine_cdm = true", if you are using Windows, you need to add enable_media_foundation_widevine_cdm = true as well.

The steps I am following are these, without any argument. If you have any guides I can read or some steps to share I would be very grateful.

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

export PATH="$PATH:/home/eduardo/2023/chrome/depot_tools"

mkdir chromium && cd chromium

fetch --nohooks --no-history chromium

cd src

./build/install-build-deps.sh

gclient runhooks

gn gen out/Default

cd third_party/ffmpeg

git am /home/eduardo/2023/chrome/add-hevc-ffmpeg-decoder-parser.patch

cd src

git am /home/eduardo/2023/chrome/remove-main-main10-profile-limit.patch

cp -R /home/eduardo/2023/chrome/widevine/* third_party/widevine/cdm

autoninja -C out/Default chrome

Can you follow this https://github.com/StaZhu/enable-chromium-hevc-hardware-decoding#how-to-build ?

I am going to closing this since the build step has already wrote in the README.md, If you still have an issue building Chromium, please comment and let me know, Thanks!
