Could you provide input 3D MXF file?

[FFmpeg-user] convert a 3D MXF to various mp4 format

[peterlingoal]

Hi All,

Could anyone tell me how to convert a 3D MXF file into following formats:
1. two separate mp4 files, left and right channel individually
2. one single mp4, with side by side 3D
3. one single mp4, with frame sequential 3D

Thanks!

Regards,
Peter

[FFmpeg-user] hyperthreading support

[Joshua Grauman]

Hello all,

I am thinking about upgrading my cpu from a Core i5-4690K to a Core 
i7-4790K. At the same clock speed, will ffmpeg run faster with the i7? 
Does ffmpeg support hyperthreading or other features of the i7?


For reference, here is the command that I want to increase the speed of:

./shm | ffmpeg -f rawvideo -pixel_format bgra -video_size $SIZE -framerate 30 
-i - -vcodec utvideo out.avi

Thanks!

[FFmpeg-user] FFMPEG can not open tcp rstp stream. Nonmatching transport in server reply. Other viewers fine.

[Brandon Glatz]

FFMPEG can not open a tcp rstp stream. Nonmatching transport in server
reply. Other viewers fine.



Just spent my entire weekend on this, still not working, I know >what< the
problem is but not >why<

Bought some ultra cheap ptz cams from china (spare me the lecture, I know
the quality and other things can connect fine) and plan to use them with
zoneminder. Zoneminder uses ffmpeg to read these as they do not work with
the built in rtsp. Fine. In ffmpeg however, then run UDP, which after a
good portion of a day messing with seems to just not work with ffmpeg
reliably. I switched it to tcp, but it wouldn't connect.

Hours of messing around later and running ffmpeg on my machine locally, I
am to the point where I can open the tcp stream from other software totally
fine, however ffmpeg just will not open it and complains about a
Nonmatching transport.  After exhausing google, I figured up wireshark to
see what the heck is going on.

The results is captures from ffmpeg, vlc, and a third party rtsp viewer are
look identical. Here is a screenshot of the captures side-by-side:

How is "paff and mbaff" signaled?
How mixed progressive and mbaff?
How mixed paff and progressive?

I wonder if -r 25 is what you want.

I suspect that the MS specification of avi does not support
aspect ratio change, just MEncoder's implementation.

I forgot:

easy to implement though.

As said this is not true (not even that you are not aware).

Hi David,

Did you try adding a Reelname & Timecode? (And, a gotcha, don’t forget to quote 
drop frame timecode…)
And / or in combination with faststart.
I can’t remember having issues when this was all done. (But it’s some time ago 
for me…)

Doesn't -loglevel verbose add some information about when streams end?
