ffmpeg-cedrus's Introduction

FFMpeg for Cedrus on Allwinner devices with sunxi kernel Based on increadible work with jemk and alcantor, we managed to update FFmpeg to include cedrus264 hardware encoder. Now it encodes I and P frames, and support resolutions up to 1080p

To us it, clone the repository, and configure by:

./configure --prefix=/usr --enable-nonfree --enable-gpl --enable-version3 --enable-vdpau --enable-libx264 --enable-libmp3lame --enable-libpulse --enable-libv4l2

and then, make && make install

Alternatively, you can install "checkinstall" package on your target, and create a deb package for easy distribution.

You may download my deb package here also.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

libavcodec provides implementation of a wider range of codecs.
libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
libavdevice provides an abstraction to access capture and playback devices.
libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analisys tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation

Hot to set bitrate?

Not support ALSA

Dear Stulluk,

I faced with problem, when im trying to make a record with audio capture, i get I got an error...

**My command: **
./ffmpeg -f alsa -i hw:1,0 -t 10 -c:a pcm_s16le -ar 44100 -ac 2 -vn -y filename.wav

Output:

But when i try to use the same command in "main" ffmpeg from original source, all work properly.

My question is how i can add alsa in your version of FFmpeg, or maybe you already fix this problem ?

### Bit More system info:

uname -a
Linux nanopiduo2 5.10.30-sunxi #trunk SMP Sun May 2 15:06:41 CEST 2021 armv7l armv7l armv7l GNU/Linux

### Build way:

cd FFmpeg-Cedrus
./configure --prefix=/usr --enable-nonfree --enable-gpl --enable-version3 --enable-vdpau --enable-libx264 --enable-libmp3lame --enable-libpulse --enable-libv4l2
make -j4
sudo make install

code in repo is I-frame only?

Hi,
I think the deb file outputs P-frames, but the compiled code using the same command does not. It does not look like the code uses the newer p-frame code by jemk. Can you commit the latest code? would be great to work with the newest version :)

can't compile, cedrus264 error

Hi, any hint about this???:

aruntu@aruntu:/etc/aruntu-extras/programs/FFmpeg-Cedrus-master$ sudo make -j2 && sudo make install
LD ffmpeg_g

Support h264 hardware decoding

Do you try to make ffmpeg support h264 hardware decoding？ it seem that vdpau-sunxi + ffmpeg is a way to do that, i am trying.

Compiled on H3, not working.

When I try to use your ffmpeg to transcode a file to H.264 this is the output I get:

ffmpeg -i bbb.divx -c:v cedrus264 -c:a copy -pix_fmt nv12 out.mkv

I tried to use the .deb file version but that did not work either so I had to compile from source.
Thanks
Ivan

Makefile modify problem

where did you add the cedrus libary flag. -lcedrus.

Object files - WTF???

I cannot fetch you repo because of of VERY LARGE OBJECT FILES
Please edit first commit while it possible, drop *.o and add it to gitignore!
You can use git-filter-branch or other same utility.
