• ffmpeg concatenate clips with broken timecode

  19 septembre 2018, par Linus679

  I’ve just received some Blackmagic footage and some of the clips are separated into chunks because of dropped frames. So let’s say I have a set of clips that looks like below for a Clip 12.

  0100_C0012_001,
  0100_C0012_002,
  0100_C0012_003,

  Is there a way to create new clip from the 3 with the name 0100_C0012 ? Also, I have to actually concatenate the clips via timecode rather then the name as the numbers seems to break at points for some reason.

  Thanks for any help.

  The info about one of the clips is as follows :

• Scroll one image top to bottom

  17 septembre 2018, par Cyber

  I am trying to scroll an image top to bottom like this video :
  https://youtu.be/8GCrrsiBLzs

  And here’s what I tried

  ffmpeg -loop 1 -t 24 -i "image.jpg" -filter_complex "color=000000:s=640x360[bg]; [bg][0]overlay=shortest=1:y='min(0,-(t)*26)'" -y out6.mp4

  But video didn’t created, ffmpeg close immediately and returns following results :

• Best way to convert .ts file to mp4 or bufferedimage[] java

  23 septembre 2018, par thekevshow

  I have an m3u8 file returning .ts file polls for streaming. Regardless, how would I convert that to an array of buffered images or something else that can be easily scraped for a buffered image. Mainly just looking for direction, as I am struggling to understand each piece there. Anything is appreciated.
