• FFMPEG RGB Lossless conversion video

  29 août 2017, par DCDCDC

  I have been experiencing difficulty in finding many answers with FFMPEG documentation, forums and here.
  What I am trying to do is a compress a screen capture video but with just RGB data.
  The steps I am currently taking are ;

  ffmpeg -f avfoundation -pix_fmt 0rgb -r "30" -i "1" -vcodec libx264rgb -pix_fmt rgb24 -crf 0 -t 25 -q 0 -y ~/Desktop/RGB.mkv

  This captures the screen on my mac. To the best of my knowledge, this creates a lossless file and I have compared screen shots that confirm this.
  The next step is where I think I have an issue.
  Because I want to run the compression on raw RGB data I need to convert the MKV to an RGB file ;

  ffmpeg -i ~/Desktop/RGB.mkv -c:v rawvideo -pix_fmt rgb24 -crf 0 -ss 00:00:03 -to 00:02:01 -q 0 -y ~/Desktop/out.rgb

  But here I have pixel variance. My guess is there is a RGB-YUV-RGB conversion happening somewhere but I am not smart enough to work out where.
  If any of you can help I would forever grateful.

  Here is a picture of the two stills side by side that shows the differences ;

  If you need anything more I can post it also.

• How can I run command line FFMPEG and accept multiple pipes (video and audio) without blocking on the first input ?

  18 février 2016, par Version135b

  I’m trying to mux h264 and aac created with MediaCodec using FFMPEG, and also use FFMPEG’s RTMP support to send to youtube. I’ve created two pipes, and am writing from java (android) through WriteableByteChannels. I can send to one pipe just fine (accepting null audio) like this :

  ./ffmpeg -f lavfi -i aevalsrc=0 -i "files/camera-test.h264" -acodec aac -vcodec copy -bufsize 512k -f flv "rtmp://a.rtmp.youtube.com/live2/XXXX"

  YouTube streaming works perfectly (but I have no audio). Using two pipes this is my command :

  ./ffmpeg \
  
  -i "files/camera-test.h264" \
  
  -i "files/audio-test.aac" \
  
  -vcodec copy \
  
  -acodec copy \
  
  -map 0:v:0 -map 1:a:0 \
  
  -f flv "rtmp://a.rtmp.youtube.com/live2/XXXX""

  The pipes are created with mkfifo , and opened from java like this :

  pipeWriterVideo = Channels.newChannel(new FileOutputStream(outputFileVideo.toString()));

  The order of execution (for now in my test phase) is creation of the files, starting ffmpeg (through adb shell) and then starting recording which opens the channels. ffmpeg will immediately open the h264 stream and then wait, since it is reading from the pipe the first channel open (for video) will successfully run. When it comes to trying to open the audio the same way, it fails because ffmpeg has not actually started reading from the pipe. I can open a second terminal window and cat the audio file and my app spits out what i hope is encoded aac, but ffmpeg fails, usually just sitting there waiting. Here is the verbose output :

  [file @ 0xb503b100] Setting default whitelist 'file'

  I think if I could just get ffmpeg to start listening to both pipes, the rest would work out !

  Thanks for your time.

  EDIT :
  I’ve made progress by decoupling the audio pipe connection and encoding, but now as soon as the video stream has been passed it errors on audio. I started a separate thread to create the WriteableByteChannel for audio and it never gets passed the FileOutputStream creation.

• avconv on debian jessie throws error when trying to convert raw video to mp4

  20 août 2017, par Vinay Divakar

  I am trying to convert a raw video captured using a Logitech USB Cam(YUYV) to mp4 using avconv. I have tried the below to do so :

  avconv -i out.raw -c copy output.mp4
  
  avconv -i out.raw -vcodec copy -acodec copy output.mp4

  but I get an error as shown below.

  root@beaglebone:~/BBB_CV/boneCV# avconv -i out.raw -c copy output.mp4
  
  avconv version 11.9-6:11.9-1~deb8u1, Copyright (c) 2000-2017 the Libav developersbuilt on Apr 23 2017 23:00:54 with gcc 4.9.2 (Debian 4.9.2-10)
  
  out.raw: Invalid data found when processing input

  I have checked here, but did not find any relevant examples for the above purpose.

  Edit : Added more details—

  I tried doing the below by adding the infile options as suggested :

  root@beaglebone:~/BBB_CV/boneCV# avconv -s 640x480 -framerate 30 -pix_fmt yuyv422 -f rawvideo -i out.raw -c copy output.mp4

  This got me rid of the previous error and some new ones popped up as shown below.

  Edit : I ran a "sudo apt-get install libav-tools" an then tried. This is what I got.
