Adding the Transform video filter to ffmpeg
1er août 2016, par aaeimfirst off I’m new to ffmpeg, and stackoverflow. so sorry If I’m doing something wrong.
Earlier I commented on a post related to this but it got deleted because it was not an answer or something. So I’m asking my own question here.
I followed this instructions https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
up untill Unzipping the ffmpeg file. Then I followed the facebook instructions
- Checkout the source for ffmpeg
- Copy vf_transform.c to the libavfilter subdirectory in ffmpeg source
- Edit libavfilter/allfilters.c and register the filter by adding the line : REGISTER_FILTER(TRANSFORM, transform, vf) ; in the video filter registration section
- Edit libavfilter/Makefile and add the filter to adding the line : OBJS-$(CONFIG_TRANSFORM_FILTER) += vf_transform.o in the filter section
- Configure and build ffmpeg as usual
and finally I ran the remaining instructions from the compilation guide.
I did the whole process a couple times but The result is always the same when I try to test.

-
When to wrap quotes around a variable
2 answers
I try to write a simple transcoding script for VHS backups with ffmpeg. But I fail to handle spaces in filenames.
I build my ffmpeg command together in the script and echo it and when I copy paste the echoed command it works, but not diretcly from the script.
Has anayone a idea whats wrong with my script ?
Script :
#!/bin/bash
# VHStoMP4Backup Script
INPUT=$1
OUTPUT="/Volumes/Data/oliver/Video/Encodiert/${2}"
command="ffmpeg \
-i \"$INPUT\" \
-vcodec copy \
-acodec copy \
\"$OUTPUT\""
if [ ! -z "$1" ] && [ ! -z "$2" ] ;
then
echo ${command}$'\n'
${command}
else
echo "missing parameters"
echo "Usage: script INPUT_FILENAME OUTPUT_FILENAME"
fi
exitScript calling :
./VHStoMP4Backup.sh /Volumes/Data/oliver/Video/RAW\ Aufnahmen/Ewelina\ -\ Kasette\ 1.dv ewe.mp4Commandline output
olivers-mac-pro:Desktop oliver$ ./VHStoMP4Backup.sh /Volumes/Data/oliver/Video/RAW\ Aufnahmen/Ewelina\ -\ Kasette\ 1.dv ewe.mp4
ffmpeg -i "/Volumes/Data/oliver/Video/RAW Aufnahmen/Ewelina - Kasette 1.dv" -vcodec copy -acodec copy "/Volumes/Data/oliver/Video/Encodiert/ewe.mp4"

Is there any way to edit just the track data of an AVI file, like mkvpropedit does with MKV files ?
20 juillet 2016, par hmj6jmhI am trying to swap the order of 2 audio tracks of an AVI file using
ffmpeg.ffmpeg -i "infile.avi" -map 0:0 -map 0:2 -map 0:1 -c copy "outfile.avi"This works but the file is being re-encoded, not copied. It takes much longer than a straight copy to finish and the resulting file is larger than the original.
Is there any way to edit just the track data of an AVI file, like mkvpropedit does with MKV files ? Command line tool preferred.
