  I check output video by command

  


  #ffprobe -v error -select_streams v:0 -show_entries stream=codec_name   -of default=noprint_wrappers=1:nokey=1 v0_s.m3u8


  


  Then the screen show

  


  hevc
hevc


  


  And this is master playlist comparison example when I use x265 (v0) and x264 (v1)

  


  #EXTM3U
#EXT-X-VERSION:7
#EXT-X-STREAM-INF:BANDWIDTH=401500,RESOLUTION=640x480

#EXT-X-STREAM-INF:BANDWIDTH=2200000,RESOLUTION=1280x720,CODECS="avc1.42c01f"
v1/prog_index.m3u8


  


  Sorry about my English.
Can you help me ? Thank you !

  


• MLT query video_codecs not listing libx264

  7 juillet 2020, par Terryn94

  Querying video codecs does not list libx264 as an available codec

  


  [terry@localhost ~]$ melt -query video_codecs | grep 264
  - h264_nvenc
  - h264_v4l2m2m
  - h264_vaapi
  - nvenc_h264
  - h264
  - h264_cuvid


  


  But I can use it in a command such as :

  


  melt avformat:DarkStar.webm -consumer avformat:output.mp4 acodec=aac vcodec=libx264


  


  and it works successfully.
This is causing a problem with kdenlive. When selecting Render and choosing the format MP4 - the dominating format (H264/AAC) the render option is disabled with the error Unsupported video codec : libx264.

  


  kdenlive checks the profile codec against the list obtained from MLT using :

  


  Mlt::Properties vcodecs(mlt_properties(consumer->get_data("vcodec")));


  


  which seems to get the same list as query video_codecs.

  


  For info here is what ffmpeg says about the codecs :

• Invalid data found when processing input. No start code is found

  23 septembre 2020, par Alex Blokha

  I am trying to concat video from many files.
But sometimes I receive an error : "Invalid data found when processing input".

  


  So, I am trying to iterate over files with ffprobe and find invalid files.
Here is the error.

  Questions :

  


  

  1. How can this be fixed, so I don't need to iterate with ffprobe and just use concat (command line : f :\prog\ffmpeg\bin\ffmpeg.exe -f concat -safe 0 -i mylist.txt -c copy output-xx.avi) ?

  


  2. If not, how can I receive an error in my .bat file and move "invalid" file to "Error" folder ?
