Screen Capture with FFMPEG and Google Native Client
18 juillet 2016, par Mohammad Abu MusaI am building a screen recorder that is based on Native Client for Google, I have ffmpeg installed and ready but I do not have experience programming in ffmpeg. so I am looking for tips to understand how to build this recorder.
My goal is to make a screen recorder and export videos as webm files, I have all the required libraries I just could not find any code examples to hack on
This is what I achieved so far

How to get rtp(javacv ffmpeg) stream from VLC as client
15 avril 2015, par SezerttI am trying to play rtp stream from vlc player which I created using javacv. Here is the code :
FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber("rtsp://10.6.0.147:554/ufirststream");
frameGrabber.start(); // First I take another stream
FFmpegFrameRecorder frameRecorder = new FFmpegFrameRecorder("rtp://239.31.31.69:4433", frameGrabber.getImageWidth(), frameGrabber.getImageHeight());
frameRecorder.setFormat("rtp");
frameRecorder.setPixelFormat(AV_PIX_FMT_YUV420P);
frameRecorder.setVideoCodec(AV_CODEC_ID_MPEG2VIDEO); <-- AV_CODEC_ID_H264
frameRecorder.setFrameRate(25);
frameRecorder.setVideoBitrate(1024); <--1024*1024*2
frameRecorder.start();
while (true) {
frameRecorder.record(frameGrabber.grab()); //grab from stream, stream with rtp
}If I choose my codec as AV_CODEC_ID_MPEG2VIDEO I can play the stream from VLC using rtp ://239.31.31.69:4433 with open network.
If I increase the quality using setVideoBitrate(1024*1024*2) the stream lags too much and if I decrease the quality is so bad.
I want to use AV_CODEC_ID_H264 as my codec to fasten things with better quality but i can’t play the stream from VLC getting error :
SDP required A description in SDP format is required to receive the RTP stream. Note that rtp :// URIs cannot work with dynamic RTP payload format (96).
I tried to get sdp using wireshark and then I realized rtp stream doesn’t have sdp :) so I tried to create my own sdp like this
c=IN IP4 239.31.31.69
m=video 4433 RTP/AVP 96
a=rtpmap:96 H264/90000and this
v=0
c=IN IP4 239.31.31.69
a=recvonly
t=0 0
m=video 4433 RTP/AVP 99
a=rtpmap:99 H264/90000
a=fmtp:99 packetization-mode=1;profile-level-id=42c01e;sprop-parameter sets=Z0LAHukBQHsg,aM4G4g==;but both seems to fail similar to this

ffmpeg h.246 plays locally in Safari, but not when hosted on s3 bucket
7 juin 2018, par Simon Rogersffmpeg h.246 plays locally in Safari, but not when hosted on s3 bucket.
I thought it was therefore a problem with S3, however a friend has sent me an
.mp4of the same file converted with Zencoder’s service and this works perfectly, which surely means it must be a problem with my encoding settings in ffmpeg ?I’m using the settings recommended for maximum compatibility :
ffmpeg -an -i mov-input-02.mov -vcodec libx264 -filter:v scale="1400:trunc(ow/a/2)*2" -movflags +faststart -pix_fmt yuv420p -profile:v baseline mov-output-02-1400.mp4Additionally, the
.webmfiles I’m converting with ffmpeg all work perfectly in Chrome, Firefox, Opera etc.!I would really appreciate any thoughts.
The video that works from Zencoder has this metadata :
