  • Issues with android-ffmpeg on Anroid Lollipop

    9 janvier 2015, par Unnati

    I am working on an application which mixes audio and video.

    I am following android-ffmpeg guardianproject to solve my purpose. The issue is that it works fine till Android Kitkat. But the process fails on Android Lollipop.

    Here is my code to run the process

    ProcessBuilder pb = new ProcessBuilder(cmd);
    
pb.directory(fileExec);
    

    
//  pb.redirectErrorStream(true);
    
Process process = pb.start();    
    

    
// any error message?
    
StreamGobbler errorGobbler = new 
    
StreamGobbler(process.getErrorStream(), "ERROR", sc);            
    

    
// any output?
    
StreamGobbler outputGobbler = new 
    
StreamGobbler(process.getInputStream(), "OUTPUT", sc);
    

    
// kick them off
    
errorGobbler.start();
    
outputGobbler.start();
    

    
int exitVal = process.waitFor();
    
sc.processComplete(exitVal);
    
return exitVal;

    How can i solve this for Lollipop ? Are there any additional files that i should include for solving this for Lollipop ?

  • FFmpeg split and concatenate issues

    27 juin 2018, par Kumar

    I am trying to use FFmpeg to split different clips, concatenate them, and then reencode the concatenated stream. Here is the command line that I would like to use with 2 input clips (actually I would like to use more than 2, but 2 would suffice for illustrating this problem) as example :

    ./ffmpeg -y -noautorotate -ss 4.9 -i in0.ts -noautorotate -i in1.ts \
    
   -threads 0 -map_chapters -1 -write_tmcd 0 \
    
   -metadata location= -max_muxing_queue_size 2000 -f mp4 \
    
   -movflags faststart -filter_complex "[0:v:0]yadif=deint=interlaced,scale=1280:720:flags=bicubic,setdar=1.7777778[v0];[1:v:0]yadif=deint=interlaced,scale=1280:720:flags=bicubic,setdar=1.7777778[v1];[v0][0:a:0][v1][1:a:0]concat=n=2:v=1:a=1[cat_v][cat_a]"
    
   -map "[cat_a]" -acodec aac -ac 2 -ar 44100 -b:a 160k -async 1
    
   -sn -map "[cat_v]" -vcodec libx264 -profile:v baseline -level 4 -b:v \
    
   5400k -preset medium -x264opts ref=3:keyint=90 \
    
   -r 30000/1001 -vsync 1 -metadata:s:v rotate= -pix_fmt yuv420p outputfile01.mp4

    But the FFmpeg hangs and is stuck at frame 0. The in0.ts has its last key frame at 4s. If I were to change the -ss 4.9 to -ss X where X <= 4.0, then there is no issue.

    My FFmpeg version is 3.3. I am aware that this problem does not exist in FFmpeg 4.0.x onwards or in FFmpeg 3.2.x but exists in 3.3.x and 3.4.x. Can someone help me understand exactly what bug has been introduced in 3.3.x and 3.4.x that there is this problem ?
