In wasm/build-scripts/configure-ffmpeg.sh you find some of the parameters FFmpeg compiles with.

But instead of running the build-with-docker.sh script, we are going to modify the project a bit.

The instructions in the readme are actually quiet good. So how can we improve on that? Compile your own ffmpeg.wasm It is probably not reasonable to download such a binary just to compress e.g. If you run mediainfo on the command line, you can even request output in XML format: mediainfo -OUTPUT=XML DV06xx.aviĪe mode=full automatic / wb mode=automatic / white balance= / fcm=manual focusĪdding the optional parameter -f will produce even more detailed information.Simulated download of 8.5 mb with simulated ADSL 16000 However, ffprobedoes not retrieve as much information as my favorite tool, Mediainfo, does, e.g., 'ffprobe' does not display the time code of first frame of the video (although the man page claims otherwise) or the recording date. For information about overall content of a multimedia file use ffprobe -show_streams -show_format DV06xx.aviĪnd for information about each single frame in a video file use ffprobe -show_frames DV06xx.avi You can use ffprobe (which comes with ffmpeg) for gathering information about multimedia files. While if i use ffmpeg ffmpeg -i IMG_0014.MOV -f ffmetadata metadata.txt I prefer using exiftool which offers me more outputs than ffmpeg.
