• youtube-dl sometime hangs with "[ffmpeg] Correcting container"

  20 mai 2018, par user292344

  /usr/local/bin/youtube-dl --version
  
  2018.05.09

  I have a bash script that attemts to download a youtube video. The output is below. The problem is that sometimes it works perfectly (completes quickly).
  But most of the time it hangs on "Correcting container....". Does anyone know why ?

• ffmpeg ... "Impossible to convert between the formats supported by the filter"

  27 novembre 2017, par hydra3333

  Using the latest ffmpeg master built as at 2017.11.26, I’m having trouble deciphering what the error messages means and, more importantly, what to do about them.

  Changing from -vf to -filter_complex did nothing (I had to try).
  The main error message seems to be

  Impossible to convert between the formats supported by the filter

  I have tried to insert "format=" and "scale" before/between/after yadif and unsharp_opencl but to no avail.

  I wonder, could it be something to do with needing hwupload/hwdownload/hwmap or is that a red herring ?

  What am I doing wrong ?

• IllegalStateException while compressing video at "dequeueOutputBuffer()" [on hold]

  11 juillet 2017, par Mr Narendra

  I’ve also checked a few or more similar posted questions, but none of them was having any satisfying response.

  My requirement is to compress videos in approx. 1-2 minutes.
  The video size restriction in my app is 500 MB and the duration limit is 4 minutes.

  The commands, I have tried -

  -i /storage/sdcard0/Videos/Lat_test.mp4 -r 20 -vcodec mpeg4 -preset ultrafast -c:a copy -tune fastdecode -strict -2 -b:v 150k
  /storage/sdcard0/Videos/output.mp4

  -y -i /storage/sdcard0/Videos/test3.mp4 -crf 24 -vcodec mpeg4 -preset ultrafast -c:a copy -me_method zero -tune fastdecode -tune zerolatency
  -strict -2 -b:v 1000k -pix_fmt yuv420p /storage/sdcard0/Videos/output.mp4

  and a few more mentioned here

  1) https://github.com/Tourenathan-G5organisation/SiliCompressor (the one using MediaCodec, instead of FFMPEG).

  2) https://github.com/lalongooo/VideoCompressor

  When tried with Samsung Galaxy Grand GT-i9082, version 5.0.1 (rooted), it failed with the below error -

  > java.lang.IllegalStateException

  Please suggest how to resolve this issue.

  Or please suggest any other better video compressing approach / sample / reference, if possible

  I have tried various samples of video compression using FFMPEG, as well as MediaCodec, but none of them are working well. A few are very very slow. and rest gets failed in a few devices.
