FFmpeg using png with tranparency and exclusion blending mode
27 août 2016, par moorejI’m trying to use the exclusion blending mode to blend together a video and a png with transparency. I’ve looked around quite a bit but I can’t find a solution that works for me. Here’s the ffmpeg command :
ffmpeg -i movie.mkv -i text_white_bg_trans.png -filter_complex\
"[1:v]setsar=sar=1,format=rgba[txt]; [0:v]format=rgba[mo]; [mo][txt]blend=all_mode='exclusion'" out_exclusion.mkvEdit : and the console output :

[libx264 @ 0x7fb10a01e200] kb/s:3830.94Edit : Here’s a frame from the output.
The output video is B&W rather than the original color (not sure why). The rectangle in the image is located where there is a block of text on a png with a transparent background. The png is the same size as the video.I’m expecting something more like this :
@Mulvya suggestion fixed the issue with color but I’m still seeing some problems with transparency being handled. I’m attaching a few different images below that each create different problems. All created in Photoshop CC (therein may lie the problem).
A transparent background with a separate text layer that is then exported by Save->png, Photoshop appears to merge these two layers but differently than when "merge layers" is chosen before export. The exported image looks like the B&W image I posted above but with color.
The in the second I merge the layers before exporting. It appears the entire image is treated as white.
In the third I draw "hello" on a transparent layer with a "soft" brush using different grays then export. Transparent areas are rendered as white, gray or translucent areas opaque or with a strange dithering "effect."
It seems I’m moving outside the realm of StackOverflow, but I’m not sure where this post would be better suited.

HTTP Livestreaming with ffmpeg
25 août 2016, par Hugo14453Some context : I have an MKV file, I am attempting to stream it to http://localhost:8090/test.flv as an flv file.
The stream begins and then immediately ends.
The command I am using is :
sudo ffmpeg -re -i input.mkv -c:v libx264 -maxrate 1000k -bufsize 2000k -an -bsf:v h264_mp4toannexb -g 50 http://localhost:8090/test.flvA breakdown of what I believe these options do incase this post becomes useful for someone else :
sudoRun as root
ffmpegThe stream command thingy
-reStream in real-time
-i input.mkvInput option and path to input file
-c:v libx264Use codec libx264 for conversion
-maxrate 1000k -bufsize 2000kNo idea, some options for conversion, seems to help
-an -bsf:v h264_mp4toannexbAudio options I think, not sure really. Also seems to help
-g 50Still no idea, maybe frame rateframerateframerateframerate ?
http://localhost:8090/test.flvOutput using http protocol to localhost on port 8090 as a file called test.flv
Anyway the actual issue I have is that it begins to stream for about a second and then immediately ends.
The mpeg command result :

# ACL:
# You can allow ranges of addresses (or single addresses)
ACL ALLOW localhost
# You can deny ranges of addresses (or single addresses)
#ACL DENY <first address="address">
# You can repeat the ACL allow/deny as often as you like. It is on a per
# stream basis. The first match defines the action. If there are no matches,
# then the default is the inverse of the last ACL statement.
#
# Thus 'ACL allow localhost' only allows access from localhost.
# 'ACL deny 1.0.0.0 1.255.255.255' would deny the whole of network 1 and
# allow everybody else.

nodejs FFMPEG argument issues

after @Mulvya comment I changed my for loop to
var volStr = '';
for (var i = 0; i < arrPairs.length; i++) {
volStr += "volume=enable='between(t," + arrPairs[i].start + "," + arrPairs[i].end + ")':volume=0";
if (i !== arrPairs.length - 1) {
volStr += ",";
}
}getting rid of the space between each grouping and it worked beautifully.
