• Minimal configure flags to configure png files to mp4 and gif ?

  24 avril 2012, par Jona

  I'm trying to configure and build ffmpeg only with the most minimum libraries needed to read set of images of png type and convert those images into a movie. The movie output support I need are gif and mp4.

  I was able to get mp4 output but gif output I can't get it to work just crashes or exist without errors.

  Could not find input stream matching output stream #1.0

  There might be some extra configure flags that can be removed too...

  Here is my configure :

  ./configure \
  
  --target-os=linux \
  
  --prefix=$PREFIX \
  
  --enable-cross-compile \
  
  --extra-libs="-lgcc" \

  --enable-version3 \

  There is the part of my music bot in Discord, I don't really know why it doesn't work. Actually, I tried to use someone's old code, so it needs to be fixed. I have cut out the most important parts of the code, which most likely had an error.
I found other questions, but there was another errors.
After trying to start the video, I get the following errors :
[out#0/s16le @ 000002452f906a00] Output file does not contain any stream
Error opening output file pipe:1.
Error opening output files : Invalid argument
