• ffmpeg : unable to use hardware encoder h264_rkmpp with software decoded ATSC OTA transmission

  20 août 2020, par Brad Bruggemann

  When attempting to hardware encode to h264 using the Rockchip MPP encoder h264_rkmpp from an ATSC source, FFMPEG errors out with :

  


  "Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scaler_0'"

  


  The sample file used in this example can be downloaded here : https://transfer.sh/BRMej/out.ts

  


  The full command used and resulting output is as follows :

  


  $ ffmpeg -loglevel 48 -c:v mpeg2video -f mpegts -i out.ts -f mp4 -c:v h264_rkmpp -c:a libfdk_aac -preset ultrafast -mbd rd -copyinkf -flags +ilme+ildct -fflags +genpts out.mp4 -y

• How to export audio from a iPhone video file with FFmpeg ?

  11 janvier 2020, par DanScripter

  UPDATE 1 the problem resides in the input read-stream. (check below)

  I am using fluent-ffmpeg (version : 2.1.2) to get a .mp3 file out of a video file that I input as a stream .createReadStream(). I output the file as a .pipe to a remoteWriteStream.

  ffmpeg -i pipe:0 -vn -f mp3 -acodec mp3 -movflags frag_keyframe+empty_moov pipe:1

  This works fine with .mp4, .webm and .mov (codec : prores) files.

  But it somehow does not want to work with a .mov out of an iPhone 11. FFmpeg is not giving me any error when running above code. It creates the .mp3 file but the size is just 152 B and it is not playable.

  I ffprobed the iPhone .mov files it returns this :

  The created .mp3 file results in a undefined.

  I already tried to take the .mov re-encode it to an .mp4 via ffmpeg and then try the above code to get the .mp3 - still does not work.

  Any advice how I can make this work ?

  thanks !

  UPDATE 1
  The problem resides in the input stream ! When I download the file to the local machine and input it as as a local file, not as a read stream, it works perfectly.

  I am creating the stream from a google cloud bucket like this :

  const myBucket = storage.bucket('myBucket');
  
  const remoteReadStream = myBucket.file(file).createReadStream();

  Since this code is perfectly working with all other codecs, what maybe the issue while creating the read stream from the google cloud from a h265 file ?

• FFMpeg - Overlay not being shown when enable=between parameter is added

  19 août 2020, par Khawar Raza

  I am using below command to add transitions effect between videos using overlays such that when one videos is about to finish, the overlay gets visible. Before showing overlays, I have to add padding and concatenate videos make one single video and then display overlays. :

-vsync 0 -c:v libx264 -pix_fmt yuv420p -map [out1] -map [audio] -preset ultrafast output.mp4


  


  But above command does not show any overlay video. If I remove enable=between(t, start, end) from overlay parameters, all the overlay gets displayed at video start. I am very beginner to video editing and to FFMpeg. Can anybody guide me what I am doing wrong here ?
