• Unable to find a suitable output format for '|' ffmpeg and python subprocess

  20 octobre 2016, par nadermx

  I currently am trying to run this command (found on this answer)

  ffmpeg -i input.flv -vf scale=320:-1 -r 10 -f image2pipe -vcodec ppm - | convert -delay 5 -loop 0 - output.gif

  in a python program using import subprocess library. The issue I’m running into is that when I run it in terminal it works fine, but when I run it in my python code I get this error

  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'https://r7---sn-p0n5jxaa-hxms.googlevideo.com/videoplayback?ms=au&requiressl=yes&mt=1476932644&pl=24&itag=22&id=o-AAJEpGAb5MS-rP073pLWFKlJ-wUTAEEIFHdx7yPOZoBS&dur=4712.861&mime=video%2Fmp4&sparams=dur%2Cei%2Cgcr%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Cratebypass%2Crequiressl%2Csource%2Cupn%2Cexpire&mm=31&ip=187.190.166.119&mn=sn-p0n5jxaa-hxms&mv=m&lmt=1471437242705377&ipbits=0&ratebypass=yes&upn=G5WdwNKKKtM&gcr=mx&source=youtube&ei=MDUIWKegH4uhugK2mbH4DQ&key=yt6&initcwndbps=3328750&expire=1476954512&signature=783E4022EDB282BE372603EF7A78C2A71B957352.B691135B7EA6AC2D7B2B2E41F1FAD9683022EE38':

                       '-vcodec', 'ppm',  '-', '|', 'convert', '-loop', '0', '-', 'gif:-', '|',
  
                       'convert', '-', 'layers', 'Optimize', '-', 'output.gif'], shell=False)

• random .ts filenames in the m3u8 file

  14 octobre 2016, par Arya Same

  Hi guys my ffmpeg line currently looks like this

  ffmpeg -i "http://x.com/x.ts" -s 810x520 -pix_fmt yuv420p -vcodec copy -acodec copy -bsf:v h264_mp4toannexb -preset baseline  -strict -2 -flags -global_header -f segment -segment_list "E:\2.m3u8"  -segment_time 10 -segment_list_size 5 "E:\2-%%3d.ts"

  it generates .ts files like 1.ts 2.ts etc..

  but if you are gonna to look to twitch.tv’s m3u8 file it looks like this

  #EXTM3U
  
  #EXT-X-VERSION:3
