How can I use ffmpeg to create video with alpha from png in C code ?
29 juin 2023, par rebornI'm trying to encode a video (mov) from png images with alpha channel in FFMPEG. Using cmd :


ffmpeg -i %d.png -r 25 -vcodec png -b:v 2500K out.mov -y


It works well.


Now I want to use in c++ code, but it got error like this :


[mov @ 0x29bf0c0] muxer does not support non seekable output


I use it in code like this :


oformat = av_guess_format("mov", nullptr, nullptr)
oformat->video_codec = AV_CODEC_ID_PNG;


The ffmpeg shows :


ffmpeg -h muxer=mov
Muxer mov [QuickTime / MOV]:
Common extensions: mov.
Default video codec: h264.
Default audio codec: aac.


The default video codec is h264, but it can create mov with png encoder using ffmpeg Command Line like above


ffmpeg -i out.mov

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'resa.mov':

How can I change this cmd to c code ?

FFmpeg video alpha merged freezes
29 mai 2017, par cdapalcI am using ffmpeg 4 Android to overlay a video with alpha channnel in a normal video. I use the following command :
String[] mergeVideosCommand = new String[]{
"-y",
"-i",
videoAlphaPath.mov,
"-i",
videoNormalPath.mp4,
"-filter_complex",
"[0:v]colorchannelmixer=aa=1[ov];[1:v][ov]overlay=0:0[video_out]",
"-map",
"[video_out]",
"-map",
"0:a",
videoResultPath.mp4
};
ffmpeg.execute(mergeVideosCommand, responseHandler);Both videos get merged, but the non-transparent one freezes after one second of playing but the video with alpha channel keeps moving and both audios work fine as well.
I have tried the same command from my computer (with ffmpeg v2.6.3) and it works fine but I need to make it work on Android (ffmpeg v3.0.1).
Anybody experienced something similar ? I would appreciate any help. Thanks. -
FFMPEG encode video with alpha channel to flv
29 novembre 2017, par treeI’m trying to encode a video (mov) to an flv with alpha channel in FFMPEG but I can’t seem to either

- find one that actually maintains the alpha
Does anyone know how to set that up ?
