No, see ticket #4184 or, even simpler, test yourself.

At some point after ffmpeg 2.8.5 I started to see this message when stream

Instead of

can I use

I'm creating a FFMPEG command line based on EVs, with filtering based on
the values of VOutputFrameSize and VFilter EVs.

I doubt it. These are IP cameras, both on decent links (one is even hard-wired

Hi,
I'm stuck with some older machines that we can't upgrade because of
software we have on them. Is it possible to install FFMPEG on OSX

yes the file work, however it is freezing every 2 seconds, the whole video.
regarding the 404, i think this was just temporary on one stream. normally
there is no 404 error.
so do you think this can be patched or any way to have this working again?

also if you watch the performer on your ipad (which is the m3u8 playlist
stream) there is no any interruption or freeze. so i might think this is
ffmpeg related?

Hi,
I am trying to add some fading in a complex filter. I`m not sure if this is
the correct approach or not -- I have a video where I want to do some
crossfading between scenes but I am stuck on simple fade. Ideally I want to
do something like this:
scene 1: frames 0-100 normal
-- frames 100-120

It's normal to have a PTS value greater than the current PCR. ISO/IEC
13818-1 says it must not exceed 1s.
The default ffmpeg demux-decode delay is 0.7s. You can set it with
-muxdelay [s].

Hi Carl,
Thanks for answering my question. I tried using a forced frame rate using
option "-r 30" and it seems to fix the issue. Out of curiosity, ffmpeg
outputs the framerate as:
Stream #0:1(eng): Video: wmv2 (WMV2 / 0x32564D57), yuv420p, 640x480,
> 800 kb/s, SAR 1:1 DAR 4:3, 1k tbr, 1k tbn,
Hello,
could you help me with this issue: why ffmpeg with option -codec copy and
output -f segment discards all pcr from original file? Is there any
possibility that we could keep original timing?
regards
