This also happens with vanilla FFmpeg if you add such logging to reap_filters. In other words, just this following diff appears to fix it. Additionally, I will be moving the debug_ts log line back to reap_filters for now since we want to know of the AV_NOPTS_VALUE frames as well.

That was not what i expected to cause this but in fact you are correct. this is a issue with log repeation removial changes from interspaced debug messages. So this is resolved for the record as others might run into this use "-v repeat+50" instead of -v 50 to avoid this thx [...]
