  lavf/url : fix relative url parsing when the query string or fragment has a colon
  This disallows the usage of ? and # in libavformat specific scheme options
  
  (e.g. subfile,,start,32815239,end,0,,:video.ts) but this change was considered
  
  acceptable.

• Findstr for multiple string patterns matching text batch or bash output in ffmpeg [duplicate]

  24 novembre 2020, par code0001

  I have a single audio only file for example “green_yellow_red.mp3”.
I have also various mp4 videos without audio with different names for example red_blue_green.mp4 pink_yellow_red.mp4 blue_red.mp4
  
The number of color strings can vary from 1 to 10. I want to output a list of videos that match at least one color string of the mp3 file and output it on a text. I want to do this for one mp3 among all the videos…And also for all mp3 against all mp4s for batch processing. I can only make list of all videos like this for now. (for %%i in (*.mp4) do @echo file '%%i') > mylist.txt
Please help me. Thank you.
P.S the color code is for description only. You can use your own naming method if the scripting would be easier in another naming system.

  


• ffmpeg/ffprobe get 'codecs' string for a video/audio stream

  18 décembre 2020, par Richard

  I'm using ffmpeg to create HLS playlists. I used ffmpeg to create them for the renditions. Now I need to create the master playlist .m3u8.

  


  I need to do this manually, for a few reasons. I have everything I need except the 'CODECS' value.

  


  How can I get this CODECS value for the video and audio streams within my file ?

  


  I cannot see the relevant data when I use ffprobe to get all the metadata about the streams.

  


  Example master manifest with CODECS :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=540863,RESOLUTION=640x360,CODECS="avc1.64001e,mp4a.40.2"
v0/prog_index.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=2339363,RESOLUTION=960x540,CODECS="avc1.64001f,mp4a.40.2"
v1/prog_index.m3u8


  


  Example of metadata I could get using ffprobe :
