Revision ed995afba1 : Make frame-wide filter-type decision fully RD-based. Overall, on all test sets,
8 juillet 2013, par Ronald S. BultjeChanged Paths :
Modify /vp9/encoder/vp9_block.h
Modify /vp9/encoder/vp9_encodeframe.c
Modify /vp9/encoder/vp9_onyx_if.c
Modify /vp9/encoder/vp9_onyx_int.h
Modify /vp9/encoder/vp9_rdopt.c
Make frame-wide filter-type decision fully RD-based.Overall, on all test sets, this gains about +0.2% on all metrics.
City is a clip where this really hurts (-1.0% on all metrics), I'm
not quite sure why yet. Maybe interesting to look into in the future.Change-Id : I6f0eecb20e72f0194633270d30bf00d76d9eae78

FFMpeg Drawtext black pixels behind the font
21 janvier 2023, par sweetngxI burn the name of the movie with drawtext to my movies converted with FFMPeg, but I noticed that the black pixels around the font are disturbing, as seen in the picture. I don't know if this is a missing line of code or the nature of drawtext itself. Do you think there is a solution to make the movie name more legible ?

Server side video mixing
16 mars 2014, par Nicolas GoyI have a serie of video files encoded in mpeg2 (I can change this encoding), and I have to produce a movie in flash flv (this is a requirement, I can't change that encoding).
One destination movie is a compilation of different source video files.
I have a playlist defining the destination movie. For example :
Video file Position Offset Length
little_gnomes 0 0 8.5
fairies 5.23 0.12 12.234
pixies 14 0 9.2Video file is the name of the file, position is when the file should be started (in the master timeline), offset is the offset within the video file, and length is the length of the video to play. The numbers are seconds (in double).
This would result in something like that (final movie timeline) :
0--5.23|--8.5|--14|--17.464|--23.2|
little_nomes **************
fairies *********************
pixies *****************Where video overlaps, the last video to be added override the last one, the audio should be mixed.
The resulting video track would be :
0--5.23|--8.5|--14|--17.464|--23.2|
little_nomes *******
fairies ***********
pixies *****************While the resulting audio would be :
0--5.23|--8.5|--14|--17.464|--23.2|
little_nomes 11111112222222
fairies 222222211112222222222
pixies 22222222221111111Where 1 or 2 is the number of mixed audio tracks.
There can be a maximum of 3 audio tracks.
I need to write a program which takes the playlist as input and produce the flv file. I'm open to any solution (must be free/open source).
An existing tool that can do that would be the simplest, but I found none. As for making my own solution, I found only ffmpeg, I was able to do basic things with it, but the documentation is terribly lacking.
It can be any language, it doesn't have to be super fast (if it takes 30 minutes to build a 1h movie it's fine).
The solution will run on opensolaris based x64 servers. If I have to use linux, this would work too. But windows is out of the question.
