libx264

I am using libX264 library for encoding purpose . After encoding data is in form of NAL Unit ()..... .This is same format( AVC) what I require but problem is one frame come in two Nal Unit ( One frame = (length,data) + (length,data) ) and i need ( One frame = (length,data) in single nal unit).While I am converting into file then play , it show first upper part of screen and then lower . My config parameter are below param.i_width = 1680//; param.i_height = 948; param.i_fps_num = some no; param.i_fps_den = 1; param.i_keyint_max = 1 ; param.rc.i_rc_method = //; param.rc.f_rf_constant = //; param

I am trying to compile Xuggler for Raspberry Pi(Running on Debian OS aka Raspbian), I followed the 'Basic Build Instructions' available here for compiling Xuggler. After I successfully installed all the prerequisites and set the correct paths, I ran the following command: ant run-tests After sometime I am facing the following error and the ant build fails at libx264: {scroll at the end of log to see the issue} common/arm/mc-c.c: In function âx264_weight_cache_neonâ: common/arm/mc-c.c:89:25: warning: assignment discards âconstâ qualifier from pointer target type [enabled by default] common/arm

I am trying to create a rtsp Server that streams the OpenGL output of my program. I had a look at How to write a Live555 FramedSource to allow me to stream H.264 live , but I need the stream to be unicast. So I had a look at testOnDemandRTSPServer. Using the same Code fails. To my understanding I need to provide memory in which I store my h264 frames so the OnDemandServer can read them on Demand. H264VideoStreamServerMediaSubsession.cpp H264VideoStreamServerMediaSubsession* H264VideoStreamServerMediaSubsession::createNew(UsageEnvironment& env, Boolean reuseFirstSource) { return new

I am attempting to encode video using libavcodec/libavformat. Audio works great, but when I try to encode video I get the following errors: [libx264 @ 0x10182a000]broken ffmpeg default settings detected [libx264 @ 0x10182a000]use an encoding preset (vpre) easy to fix using the command line ffmpeg, but I am trying to do this in C. my options are AVStream *pVideoOutStream = av_new_stream(pOutFormatCtx, 0); AVCodecContext *pVideoOutCodecCtx = pVideoOutStream->codec; pVideoOutCodecCtx->codec_id = CODEC_ID_H264; pVideoOutCodecCtx->codec_type = CODEC_TYPE_VIDEO; pVideoOutCodecCtx->bit_rate =

When I try to convert a webm file to mp4 the output is very very choppy and it appears as if many frames have been dropped by ffmpeg I used the following commands to convert ffmpeg -i movie.webm movie.mp4 ffmpeg -i movie.webm -vcodec libx264 movie.mp4 ffmpeg -i movie.webm -vcodec libx264 -qscale 0 movie.mp4 All of them have the same problem. When I use ffprobe it seems to show the frames more or less properly.

I want to upload video files to server and compress before uploading. I'm using ffmpeg libx264. I have seen viber can upload 30 second video file of size 78MB within a minute [reduce it's down to 2.3MB]. I want to know how do they do it so fast?
