• FFMPEG php HLS and DASH conversion

  21 juillet 2020, par Angus Simons

  I'm using this repo https://github.com/aminyazdanpanah/PHP-FFmpeg-video-streaming to encode video in hls and then reproduce on the front end.

  


  After creating all the hls segments correctly the php script fail to execute the command below.
The command getting error is the next one :

  


  '/usr/bin/ffmpeg' '-y' '-i' 'source.mp4' '-c:v' 'libx264' '-c:a' 'aac' '-bf' '1' '-keyint_min' '25' '-g' '250' '-sc_threshold' '40' '-use_timeline' '1' '-use_template' '1' '-init_seg_name' 'dash_init_$RepresentationID$.$ext$' '-media_seg_name' 'dash_chunk_$RepresentationID$_$Number%05d$.$ext$' '-seg_duration' '10' '-hls_playlist' '0' '-f' 'dash' '-adaptation_sets' 'id=0,streams=v id=1,streams=a' '-map' '0' '-s:v:0' '256x144' '-b:v:0' '830k' '-map' '0' '-s:v:1' '426x240' '-b:v:1' '969k' '-map' '0' '-s:v:2' '640x360' '-b:v:2' '1162k' '-map' '0' '-s:v:3' '854x480' '-b:v:3' '1453k' '-map' '0' '-s:v:4' '1280x720' '-b:v:4' '1938k' '-map' '0' '-s:v:5' '1920x1080' '-b:v:5' '2907k' '-strict' '-2' '-threads' '12' 'dash.mpd'


  


  Here there is the error printed executing the command with CLI :

• ffplay playing videos very slow and choppy

  2 juin 2014, par Pavan K

  I am trying to compile ffplay from sources to run on pcduino running ubuntu

  If I install ffplay via sudo apt-get install ffmpeg the videos play perfectly But I tried to compile ffplay from the sources using the guide here ffmpeg compilation the videos play terribly slowand look very very choppy.

  Do I have to use some specific flags for compilation. I just would like a bare bones video player ffplay. I do not want to encode or do any heavy computation with the binary.

  ffplay verison is

• JavaCV Create Compatible MP4

  15 juin 2017, par Hamish258

  Trying to modify JavaCV 3.2.0 sample https://github.com/bytedeco/javacv/blob/master/samples/WebcamAndMicrophoneCapture.java, to produce an mp4 that quicktime on macOS 10.12.5 can use. Output mp4 works fine with VLC but for the software I’m producing I’d like to minimise users having to install additional products.

  The sample code produces the following output

  The constrained baseline to 3.1 should produce usable mp4 according to https://trac.ffmpeg.org/wiki/Encode/H.264

  If I use the command line ffmpeg -i alatest.mp4 -pix_fmt yuv420p alantest.mp4 it produces a usable mo4, even though as you can see above yuv420p is the pixel format in use so there’s something else I don’t understand, the code snippet from the sample link is :

     FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("alatest.mp4",1280, 720, 2);
   recorder.setInterleaved(true);
   recorder.setVideoOption("tune", "zerolatency");

   recorder.setVideoOption("crf", "28");

   recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
   recorder.setPixelFormat(avutil.AV_PIX_FMT_YUV420P);
   recorder.setFormat("flv");
   recorder.setFrameRate(30);
   recorder.setGopSize(60);
