xuggler - Xuggle API - Output video file size increasing. -
i trying run basic scenario using xuggle api, giving input flv file , writing flv file.
i used same input parameters (e.g. bit rate, width , height); however, after conversion, getting much bigger output video file 2-3 times of input video size.
please see below ffmpeg command output of both videos.
input video:

i using below code processing. note using same input parameters of video.
public void onaddstream(iaddstreamevent event) { int streamindex = event.getstreamindex(); istreamcoder streamcoder = event.getsource().getcontainer() .getstream(streamindex).getstreamcoder(); if (streamcoder.getcodectype() == icodec.type.codec_type_audio) { streamcoder.setbitrate((int) audiobitrate); writer.addaudiostream(streamindex, streamindex, audiochannelcount, audiosamplerate); } else if (streamcoder.getcodectype() == icodec.type.codec_type_video) { streamcoder.setwidth(video_width); streamcoder.setheight(video_height); streamcoder.setbitrate((int) videobitrate); writer.addvideostream(streamindex, streamindex, video_width, video_height); } super.onaddstream(event); } public void onvideopicture(ivideopictureevent event) { ivideopicture pic = event.getpicture(); if (videoresampler == null) { videoresampler = ivideoresampler.make(video_width, video_height, pic.getpixeltype(), pic.getwidth(), pic.getheight(), pic.getpixeltype()); } ivideopicture out = ivideopicture.make(pic.getpixeltype(), video_width, video_height); videoresampler.resample(out, pic); ivideopictureevent asc = new videopictureevent(event.getsource(), out, event.getstreamindex()); super.onvideopicture(asc); out.delete(); } public void onaudiosamples(iaudiosamplesevent event) { iaudiosamples samples = event.getaudiosamples(); if (audioresampler == null) { audioresampler = iaudioresampler.make(audiooutputchannels, samples.getchannels(), audiooutputrate, samples.getsamplerate()); } if (event.getaudiosamples().getnumsamples() > 0) { iaudiosamples out = iaudiosamples.make(samples.getnumsamples(), samples.getchannels()); audioresampler.resample(out, samples, samples.getnumsamples()); audiosamplesevent asc = new audiosamplesevent(event.getsource(), out, event.getstreamindex()); super.onaudiosamples(asc); out.delete(); } } am missing here, causing problem?
