Hi,
I'd like to know if there's a way to go on recording even when the
source will disappear for a while?
Reason:
I plan to record several sources at a time as independent recordings.
Source A will become Video A, Source B will become Video B and so on.
Source A will be the "master" and the d

Does piping really work under Windows? The Windows equivalent to 'cat' would be
'dir /b'. But changing the command line this way creates an error that
basically says that the input stream is empty.
I couldn't find any example

The problem is now solved. The previous init.mp4 was corrupted. I tried

I have an encoder which gives me the option of generating sliced I frames.
These frames have a slice of I frame inserted in each frame, but there is
never a full I frame. If I use FFMpeg to rebroadcast the stream to an HLS
stream, then it works well when I'm not using sliced I frames, but only

Hello
I am trying to record my computer's screen together with the sound from
speakers and (occasionally) microphone. While the record is made
successfully, it is problematic: when watching on VLC it is good, but on
Kdenlive or YouTube audio and video are out of sync.
I am using Xubuntu 16.04.
Win32 Version:
ffmpeg-20161006-0212867-win32-static version and before works with ass
subtitle , can show video window.
After ffmpeg-20161007-c45ba26-win32-static version , can't show video
window .
Why?

As a follow up, if anyone wants to enable and use fast (index) seeking
in HLS videos while they are being transcoded, the secret is to use
the
-hls_playlist_type event
parameter as mentioned in the doc here:

Is that really all it says? Nothing else? No URL?
Please give an example.

FFmpeg is (a library and) a transcoding tool, the specific
recording format "data" is currently broken.
Use mplayer -dumpstream or tcpdump or tools/aviocat

If the issue is reproducible with current FFmpeg git head,
please dump the udp stream to a file (with tcpdump or
similar) and provide a sample for testing.
