• Exoplayer FFMPEG issue. Video froze on the first frame after adding Exoplayer FFMPEG extension

  13 mai 2020, par Aravind

  I am working on adding Exoplayer and it works fine. But some of the videos were playing without audio, it plays fine in VLC medial player. So I was suggested to add Exoplayer FFMPEG. I added Exoplayer FFMPEG extension and I modified the code as below,

  



  val videoTrackSelectionFactory: TrackSelection.Factory = AdaptiveTrackSelection.Factory(BANDWIDTH_METER)
val trackSelector: TrackSelector = DefaultTrackSelector(videoTrackSelectionFactory)

val renderersFactory: RenderersFactory = DefaultRenderersFactory(mContext, null, EXTENSION_RENDERER_MODE_PREFER)
mPlayer = ExoPlayerFactory.newSimpleInstance(mContext, renderersFactory, trackSelector)
mediaSource = mMediaSourceUri?.let { createLeafMediaSource(it) }!!
mPlayer.prepare(mediaSource)


  



  After I modified the video stuck with the first frame and it keeps on loading. I checked the log and I didn't see any error.

  



  

  



  Can anyone help me with this ? Thanks in advance !

  


• Output filename extension in fswatch and ffmpeg

  30 juin 2020, par rr09

  I'm having issue with the file-naming extension output. My input is JPG files that needs to convert to MP4 using FFMPEG. However, when I run the code below it output as img1.jpg.mp4 including the input file extension instead of just img1.mp4.

  


  fswatch -e ".*" -i "\\.jpg$" . |xargs -n1 basename|xargs -n1 -t -I {} sh -c 'pwd;[[ -f {} ]] && ffmpeg -y -loop 1 -i "{}" -vf "fade=t=in:st=0:d=1,fade=t=out:st=2:d=1" -preset "ultrafast" -c:v libx264 -t 3 -pix_fmt yuv420p "{}.mp4"'


  


  Any help is much appreciated.

  EDITED :

  


  BTW I also tried a loop to do the trick like the code below, but I'm looking to more neat solution to fix it in the same line of code above or call function after FSWATCH successful operation.

  


   for file in
     *.jpg.mp4; do
        mv "$file" "$(basename "$file" .jpg.mp4).mp4"
    done


  


• FFmpeg same Filename for output but without extension with python

  10 septembre 2020, par Ptibouc77

  i'm kinda noob with Python but i managed to make this code to encode multiple videos files from a folder to H265, everything woks fine exept for the output name.

  


  Actually the output name keep the old file extension with the new one like this "MyMovie.mov.mp4" and i want it to be named like this "MyMovie.mp4" is there any way to exclude the original file extension from the output file ?

  


  import os, sys, re

input_folder= '/content/drive/My Drive/Videos'
output_folder= '/content/drive/My Drive/Videos/X265' 
quality_setting = '30'
file_type = 'mp4

my_suffixes = (".mp4", ".mov", ".mkv", ".avi", ".ts", ".flv", ".webm", ".wmv", ".mpg", ".m4v", ".f4v")

from pathlib import Path
Path(output_folder).mkdir(parents=True, exist_ok=True)

for filename in os.listdir(my_folder):
   if (filename.endswith(my_suffixes)):
       cmd = !ffmpeg -v quiet -stats -hwaccel cuvid -i "$input_folder/{filename}" -metadata comment="X265-QF$quality_setting-AAC" -c:v hevc_nvenc -preset:v slow -rc vbr -cq $quality_setting -c:a aac -b:a 160k "$output_folder/{filename}.$file_type"


  


  Ps : This code is used on Google Colab that's why i need this with python.
