I have tried to make a bitstream filter for FFmpeg that drops the nth keyframe for positive numbers and allows the first n keyframes and drops the rest for nonpositive numbers, called "datamosh":
ffmpeg -i input.webm -bsf:v datamosh=target=20 -c copy output.webm
outputs the error:
Option 'target' not found
[vost#0:0/copy ⓐ 0x54edc40] Error parsing bitstream filter sequence 'datamosh=target=20': Option not found
Here is the code for the "datamosh" bitstream filter:
#include "bsf.h"
#include "bsf_internal.h"
#include (...)

Trying to encode XDCAM HD422 MXF with FFMPEG
But can't know specific setting for encoder/format/mux
Anyone can show me sample code or give some advice for that ?
