ffmpeg command execution never stops
19 août 2020, par Khawar RazaI am trying to concatenate 3 videos of different resolutions and overlaying 2 videos as transition effects(though the chroma key color removal is not yet implemented) between videos using below command :


ffmpeg 
-i input1.mp4 
-i input2.mp4 
-i input3.mp4 
-i transition1.mp4 
-i transition2.mp4 
-filter_complex

-c:v libx264 -pix_fmt yuv420p -map [out1] -map [audio] -preset ultrafast output.mp4


I get success only with few videos. Most of the times the command execution never stops. It keeps on appending something to the output video file even for hours. Here is the output from console :

HTTP Livestreaming with ffmpeg
12 décembre 2020, par HugoSome 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.flv



A breakdown of what I believe these options do incase this post becomes useful for someone else :



sudo



Run as root



ffmpeg



The stream command thingy



-re



Stream in real-time



-i input.mkv



Input option and path to input file



-c:v libx264



Use codec libx264 for conversion



-maxrate 1000k -bufsize 2000k



No idea, some options for conversion, seems to help



-an -bsf:v h264_mp4toannexb



Audio options I think, not sure really. Also seems to help



-g 50



Still no idea, maybe frame rateframerateframerateframerate ?



http://localhost:8090/test.flv



Output 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 :

# Format of the stream : you can choose among:

# mpegvideo : only MPEG-1 video
# mp2 : MPEG-2 audio (use AudioCodec to select layer 2 and 3 codec)
# ogg : Ogg format (Vorbis audio codec)
# rm : RealNetworks-compatible stream. Multiplexed audio and video.
# ra : RealNetworks-compatible stream. Audio only.
# mpjpeg : Multipart JPEG (works with Netscape without any plugin)

How to overlay 2 videos, one is main second one is overlaying it, and play sound simultaneously. using FFMPEG in ANDROID STUDIO
6 août 2020, par Dusan Lilicas title say I'm trying to overlay 2 videos and play sound simultaneously. So far i managed to put 1 video over another using this command :


String[] command = {"-i", mainVideoPath, "-vf",
 "movie=" + overlayVideo + ", scale=300:-1[inner]; [in][inner]overlay=10:10[out]" ,combinedVideoOutput};


and this works but I have 3 problems here.
First, video is rotated by 90 degrees (overlay video), second Audio is played only from main video (I want to play sound from both videos simultaneously), and third overlay video is longer (for example : overlayVideo duration is 10 seconds and main video last 7 seconds) then mainVideo, so i want to final video last as long as mainVideo, as soon as mainVideo finish, overlayVideo should also stop (need to cut it prolly ?)


String[] command = {"-i", mainVideoPath, "-i", overlayVideo ,
 "-filter_complex", "[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];[base][wm]overlay=10:10" ,combinedVideoOutput};


Using this command i have 2 problems same as above except video is not rotated here.
I have to say that I'm not very familiar with ffmpeg commands. I was trying to figure it out from documentation link to documentation but without any success.
I know that I'm missing some filters like -map merge or something but can't figure it out.
Thanks in advance !

EDIT2 :
After adding "-shortest" to command i managed to cut overlay video to be the same length as main video (because overlay video is always longer then mainVideo, "-shortest" take short one duration. So now, command looks like this :


String[] command = {"-i", mainVideoPath, "-i", overlayVideo ,"-filter_complex", 
"[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];[base][wm]overlay=10:10", "-shortest", combinedVideoOutput};


Rotation is good so only need to merge their audios. For now, only mainVideo audio is playing, overlay video audio isn't


EDIT 3 :


String[] command = {"-i", mainVideoPath, "-i", overlayVideo ,
 "-strict", "experimental",
 "-filter_complex",
 "[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];" +
 "[base][wm]overlay=10:10; " +
 "pan=stereo|c0=2*c0|c1=3*c0[a0];[1:a]pan=stereo|c0=1*c0|c1=4*c0[a1];[a0][a1]amix=inputs=2:duration=first:dropout_transition=2",
 "-shortest" ,combinedVideoOutput};


With this command i managed to overlay videos, and play sound from both of them, rotation is good, but -shortest doesn't work now. Only existing problem now is to make them to last as shorter one (mainVideo is always shorter) ???


EDIT 4 :


This is finally working command


String[] command = {"-i", mainVideoPath, "-i", overlayVideo,
 "-filter_complex",
 "[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];" +
 "[base][wm]overlay=10:10:shortest=1;" +
 "pan=stereo|c0=2*c0|c1=3*c0[a0];[1:a]pan=stereo|c0=1*c0|c1=4*c0[a1];" +
 "[a0][a1]amix=inputs=2:duration=first:dropout_transition=2",
 combinedVideoOutput};
