  • FFMPEG overlay issue for 2 videos, sound missing from second input

    7 septembre 2014, par Abhishek Singh

    I’m trying to achive an overlay with ffmpeg wich take the two flv files as input and make a output and both videos playing simultaneously. things are working fine with below ffmpeg command :

    ffmpeg -i input1.flv -vf "[in] scale=359:320, pad=2*iw+6:ih [left]; movie=input2.flv, scale=359:320 [right]; [left][right] overlay=365:0 [out]" -b:v 3600k -y output.flv

    But issue is with the sound of second video and that is missing from the output.flv, only input1 sound is available in the output.flv.

    Console output is :

    i think -map is filter that is for the audio handling of both video.see this link.

    Superimposing two videos onto a static image ?

  • Setting Encoding Codec Profile in Xuggler

    19 octobre 2012, par Alterscape

    I am attempting to transcode video into Apple ProRes 422 Proxy using the prores_kostya codec in ffmpeg, via Xuggler. I can successfully set up a video encoder and encode to the default prores_kostya settings, but I would like to configure the encoder to use the 'proxy' profile (as per the developer's site). I have the following configuration code in my application :

    IMediaWriter writer = ToolFactory.makeWriter(OUTPUT_FILE);
    

    
writer.addVideoStream(0, 0, outputCodec, WIDTH, HEIGHT);
    
writer.addAudioStream(1, 2, ICodec.ID.CODEC_ID_PCM_S16LE, 2, 48000);
    

    
IStreamCoder streamCoder = writer.getContainer().getStream(0).getStreamCoder();
    
LOGGER.info("profile is: {}", streamCoder.getPropertyAsString("profile"));
    
streamCoder.setPixelType(IPixelFormat.Type.YUV422P10LE);
    
streamCoder.setFrameRate(IRational.make(30,1));
    
streamCoder.setTimeBase(IRational.make(1,30));
    
streamCoder.setProperty("profile", "proxy");
    
LOGGER.info("profile is: {}", streamCoder.getPropertyAsString("profile"));

    The output of this block of code is below. Note that profile remains -99, and a bizarre error about parens is thrown.

    1637 [main] INFO  n.r.o.corpus.devel.MediaConverter - codec is com.xuggle.xuggler.ICodec@2074329184[type=CODEC_TYPE_VIDEO;id=CODEC_ID_PRORES;name=prores_kostya;] 
    
1638 [main] INFO  n.r.o.corpus.devel.MediaConverter - profile is: -99 
    
1639 [main] ERROR org.ffmpeg - [Eval @ 0x10d7d7108] Undefined constant or missing '(' in 'proxy' 
    
1639 [main] ERROR org.ffmpeg - [prores_kostya @ 0x7faf7c874c00] Unable to parse option value "proxy" 
    
1639 [main] INFO  n.r.o.corpus.devel.MediaConverter - profile is: -99

    Any idea what's going on here ?

  • ffmpeg error message : MB Rate > level limit [closed]

    10 juin 2013, par pleasehelpme

    Running the .bat script for rotating a video's orientation generates this error message :

    [libx264 @ 0162fb80] MB rate (108000000) > level limit (2073600)

    It appears on some videos, and the outputs of these videos are corrupted. How to fix this error ?
