Slow in Docker Container for AV1

stevezau commented 7 months ago

There is a known issue where AV1 codes are extremely slow to process when using the docker container.

For example, it runs at 0.8x speed in the container; on the native machine, the exact same FFmpeg command runs at 10x. The only difference I can see is that the av1 lib in the container uses [libaom-av1 @ 0x559ad8f192c0] 3.8.2, while the native host uses [libdav1d @ 0x55e42e5f4640] libdav1d 1.2.1.

I am unsure how to change that as I use the linuxserver/ffmpeg base image.

Leaving this ticket open, I hope a ffmpeg expert can help as i've run out of ideas.

@stevezau Hi there,

I recently discovered this project. Unfortunately, I use AMD graphics, so I cannot test the project that relies on NVIDIA graphics (I will look into whether adding AMD encoding support is feasible).

To my knowledge, libaom-av1 and libdav1d serve different purposes. The former is for encoding, while the latter is for decoding.

Here are a few suggestions that might help you resolve this issue:

Check the available encoding libraries and codecs within the Docker environment using ffmpeg commands. You can use the following command to list all available encoders and decoders:
```
ffmpeg -encoders
ffmpeg -decoders
```
If the result does not contain libdav1d or the encoder/decoder/lib you are looking for, you can try installing it with apt .
```
sudo apt-get update
sudo apt-get install libdav1d-dev
```
After installing the necessary libraries, you may need to rebuild ffmpeg from the source to include the newly added libraries.

Additionally, here are the commands I recently used to rebuild ffmpeg with NVIDIA CUDA in a different environment. These may not perfectly fit your situation, so you might need to replace some commands accordingly:

# You may need to check the version of the nvidia-driver
sudo apt install nvidia-driver-525 nvidia-cuda-toolkit build-essential yasm cmake libtool libc6 libc6-dev unzip wget libnuma1 libnuma-dev openssl libssl-dev libass-dev libfdk-aac-dev libmp3lame-dev libopus-dev libtheora-dev libvorbis-dev libvpx-dev libx264-dev libx265-dev -y

git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg/ --depth=1

./configure --enable-nonfree --enable-cuda-nvcc --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 --enable-openssl --enable-gpl --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree --enable-libaom

sudo make && sudo make install

If this resolves the issue, the ffmpeg in the Dockerfile's FROM might be unnecessary. Alternatively, you might find that someone else has already published a Docker image tailored for NVIDIA environments, which could be worth looking into.

Good luck!

~I think the problem might be solved if the docker container could access the host system's lib and use its own ffmpeg. (Not verified, just an idea)~

On second thought, this is not a good idea. I didn't think about the case where the host system and the docker environment are different. This could cause bigger problems.

Hey, see the output of ffmpeg encoders/decoders. So, perhaps it is missing libdav1d? I am out of my depth here so I will use your suggestions then hopefully test it works.

Correct misrepresented information:

To my knowledge, libaom-av1 and libdav1d serve different purposes. The former is for encoding, while the latter is for decoding.

libaom-av1 seems to have been used for both encoder and decoder. (libdav1d is for decoder only.)

Then, when I guessed the problem, it seems that the performance was high because libdav1d was used in the host environment, and the performance was low because libom-av1 was used in the Docker container environment.

Check a little more precisely whether ffmpeg can use the libav1d codec in the Docker container.
First, check whether the libav1d library is installed in the Docker environment with the following command. (Checking with ffmpeg --codes seems to be a little more accurate.)

ffmpeg -codecs | grep libdav1d

In my environment, the output is as follows.

# ...
 DEV.L. av1                  Alliance for Open Media AV1 (decoders: libdav1d libaom-av1 av1 av1_cuvid av1_qsv) (encoders: libaom-av1 librav1e libsvtav1 av1_nvenc av1_qsv av1_vaapi)

(decoders: libdav1d in Alliance for Open Media AV1)

If there is a decoder, manually specify the decoder with an option such as -c:v libdav1d when decoding ffmpeg to check if it is decoded.
If you cannot check the decoder, proceed with the remaining items below.

sudo apt install libdav1d-dev
# If there is nothing new to install, you can skip it because the library is already included in the Docker image.

Include libav1d-dev when building ffmpeg.

./configure --enable-nonfree \
# .... 
--enable-libdav1d
# ...

(I didn't know you'd use all the ./configure settings I suggested. They are the commands I used to build ffmpeg for my specific case, and there may be options you don't need.)

After make install, check if ffmpeg command includes --enable-libdav1d. If you type ffmpeg command without any options, configuration item will appear.

The configuration section should contain --enable-libdav1d. (If it doesn't show up, you need to check what file ffmpeg is running as. Since the Docker container is currently running as the linuxserver/ffmpeg:7.0.1 image, there may be two ffmpeg binary files. And if you are using a custom-built ffmpeg, you probably don't need to use the Docker image that includes ffmpeg.)

Now, let's start the thumbnail and check if it worked using libdav1d.

@stevezau i will try fixing this later.or adding a proper fix

aptalca commented 3 months ago

Linuxserver image was updated with support for libdav1d in https://github.com/linuxserver/docker-ffmpeg/pull/79 If you initiate a new build of your docker image, it should support the dav1d decoder

stevezau commented 3 months ago

thank you!

stevezau commented 3 months ago

hmm, it is still very slow/has issues when running on av1 files in the container. ill have to dig in and debug later.. as best I can as I'm out of my depth here :)

stevezau commented 3 months ago

Ignore that.. I updated the code to change to "auto" hwaccel mode. FFMPEG should now choose the best path. With the latest update to ffmpeg container it should also now support AV1 properly. Closing this issue as resolved.
