...there is no stream 1

[markfilipak]

Thank you for FFMPEG.

Support issue:
Note in the console output below, "Timestamps are unset in a packet for stream 1". I don't mean to quibble but there is no stream 1. Does FFMPEG mean input stream 0:1? (To novices who aspire to make sense of FFMPEG output, this is an important issue. To me, it, and the following sub-issue are, important).

What I seek to accomplish:
Fix time stamps using the bit stream filter without transcoding (remux only).

Excuse me. Upon reviewing this, I realized I need to get TB, STARTDTS, and STARTPTS into it. I'm closing it and will resubmit when I, 1, get the latest version, and 2, confirm that there's still an issue. Sorry.

"mean input stream 0:1"

No, 0 means first input (concat does not count, use multiple -i options), 1 means 2nd stream.

Replying to Balling:

"mean input stream 0:1"

No, 0 means first input (concat does not count, use multiple -i options), 1 means 2nd stream.

Thank you. Yes, I knew that, but "Timestamps are unset in a packet for stream 1" is not the same as "Timestamps are unset in a packet for the first stream". (And, based on my previous experiments, I believe concat does count as an input -- I have referenced in the past, e.g. '-codec:0:v'.)
