Description
Attempt to push output via rtsp and one can observe that the log contains no details regarding size nor bitrate.
Example:
frame=1221110 fps= 29 q=36.0 size= 0kB time=11:18:22.36 bitrate= 0.0kbits/s dup=1220 drop=0 frame=1221125 fps= 29 q=36.0 size= 0kB time=11:18:22.86 bitrate= 0.0kbits/s dup=1220 drop=0 frame=1221140 fps= 29 q=36.0 size= 0kB time=11:18:23.36 bitrate= 0.0kbits/s dup=1220 drop=0 frame=1221156 fps= 29 q=36.0 size= 0kB time=11:18:23.90 bitrate= 0.0kbits/s dup=1220 drop=0 frame=1221171 fps= 29 q=36.0 size= 0kB time=11:18:24.40 bitrate= 0.0kbits/s dup=1220 drop=0

It's obviously keeping track of the output kbps given the last line [libx264 @ 0x10180f400] kb/s:231.50 but why it's not being written to the log is currently beyond me.
Using the same binary and command, but output via rtmp seems to report correctly (to bad I can't use rtmp in my application use case.):

I observe the same (correct) behavior when I shoot straight flv as well.
Please let me know if I've not included everything necessary.
Thanks!

iam happy to look into this and fix it but how do i reproduce it ? is a account on wowza.server.com needed or can it be reproduced without this? maybe some vlc/ffmpeg/whatever commands i can copy and paste to reproduce it ? I suspect fixing this if i can reproduce it would take me 5min but figuring out how to reproduce it well i dunno where to start :)

Thanks.
I actually have a couple patches for ffmpeg.c and libavformat/utils.c that I need to submit for review.
These produce accurate output data for each non-seekable output stream (there was a FIXME in ffmpeg.c: 'print_report' to address this...). Additionally it accurately tracks the amount of kBytes that have been shipped since the encode started.
example output:
frame= 991 fps= 30 q=24.0 kB= 2299.2 kbps= 571.6 size= 0kB time=00:00:31.86 bitrate= 0.0kbits/s dup=1 drop=0 frame= 1021 fps= 30 q=24.0 kB= 2369.8 kbps= 564.8 size= 0kB time=00:00:32.86 bitrate= 0.0kbits/s dup=1 drop=0 frame= 1051 fps= 30 q=24.0 kB= 2438.7 kbps= 551.5 size= 0kB time=00:00:33.86 bitrate= 0.0kbits/s dup=1 drop=0 frame= 1081 fps= 30 q=24.0 kB= 2504.6 kbps= 527.1 size= 0kB time=00:00:34.86 bitrate= 0.0kbits/s dup=1 drop=0 frame= 1111 fps= 30 q=24.0 kB= 2574.6 kbps= 559.9 size= 0kB time=00:00:35.86 bitrate= 0.0kbits/s dup=1 drop=0
Granted, my interests lie in non-seekable output as I'm using this to stream live video. If there's a procedure that I need to follow to ensure that things work as expected for alternate outputs, please advise.
I'll be honest, I'm not sure how well these additional fields are going to be received. We didn't want to mess with the bitrate entry since I figured others were probably using mechanisms that expected that to be there.
I'll try to rebase tomorrow morning first thing and get these changes in for review.
Judging by the above, do you have any comments that can be shared with me now?
comment:5 by , 12 years ago
It turns out, that bitrate on a non-seekable stream eventually ends up as a long running average if the stream is up for extended periods of time. No amount of scene change triggered any variance in streams that were up for instances running 5+ days...

Replying to michael:

I would think that a simple output to the local host via rtsp would exhibit the same behavior. I'll admit, I haven't had time to try. I'll see if I can get some details on that today. I'm hoping to have the patch submitted before that though. I have to review the latest HEAD as my rebase yesterday had some conflicts so we need to figure out what failed on the rebase first.
maybe some vlc/ffmpeg/whatever commands i can copy and paste to reproduce it ?
This was all local client centric. I would imagine if you used the same command I posted in the ticket (with a local file as input) and output to a localhost rtsp port... you should see the same results in your terminal or wherever you're landing the output log via stderr.
I suspect fixing this if i can reproduce it would take me 5min but figuring out how to reproduce it well i dunno where to start :)
I can appreciate that. Let me know if anything in my above comments doesn't jive and we can sync up on getting it reproduced.
Again, I'm trying to get a patch submitted (I've just not had time to get it sent :( ) to solve this as well. It's tested and reports the output above. If anyone sees any problems with this please let me know.
I compiled the latest version from the git repo last night, because I told Carl I would try.
