If this question is closed. Then we should also close all the "how to compile ffmpeg" spam.

comment Freeze frame effect with ffmpeg
@Code_Ed_Student I've relooked at the resulting file, and you are correct. It does terminate way earlier than it should. I believe that it a bug (apparently in both classic ffmpeg and avconv), i'm going to file a bug now.

@Code_Ed_Student Most likely changing timestamps didn't move your initial video. Can you go to the man page, there should be example useages of setpts filter. Give them a try on the file that you are encoding, do they work?

@Code_Ed_Student With my setup you should have 5+15=20 second video, what did you get? And oh yes, i use libtheora so often that i type it almost automatically by now, you can use whatever codec and file format you wish.

comment Freeze frame effect with ffmpeg
@Code_Ed_Student Ok, keep in mind that i don't have an ffmpeg setup, so my help will be limited. Can you try to just generate the frozen frame video -loop 1 -i file.jpeg -filter_complex "[0:v]trim=start=0:end=5[final]" -map "[final]" -c:v libtheora out.ogv let's see if this works, we'll continue from there.

@Code_Ed_Student I am unsure what is happening with your setup, so i've added how to make avconv with the same options as mine.

comment how to Rotate a 3gp video without re-encoding
@poor Ok, i now feel dumb. There were several questions, some of which have provided a very in depth explanations on how to rotate mjpeg via bash scripts and imagic. It really feels like somebody has gone on a cleaning spree and has removed too much. Alternatively i've dreamt all those questions. I'm trying to find them now on other SE.

@poor I've clicked downvote on your answer by some weird accident. Tried to undo, but it didn't let me.

It has been answered to death already. Not possible, unless container supports it or you are using MJPEG codec, which you are not.

comment Can I run this in one command line (ffmpeg)
@LordNeckbeard Ok, let's leave it at "It cannot be scripted due to classic ffmpeg not having concat demuxer" then.

@LordNeckbeard Which is why i have said "i'm sure there are similar classic ffmpeg approaches". PLEASE STOP TROLLING!!!

You could always write a script. Look at something like libav.org/faq.html#How-can-I-join-video-files_003f (i'm sure there are similar classic ffmpeg approaches)

comment Avconv rotating mpeg4 - video loses quality
Shouldn't we start marking "how to rotate without reencoding" to be duplicates by now?
