Hi,
Is there a way to add custom key/val pairs to the info sent when using
the "-progress" option?
For example, to the current output below,
Progress output
frame=480
fps=27.9
stream_0_0_q=-1.0
bitrate= 80.5kbits/s
total_size=193518

A solution in a single process would be ideal. As CPU load is low
anyway, I would prefer to keep this in a single instance if piping
Hi,
I have the following working command.
It takes a set of video/audio as input and outputs the transcoded result
in two formats. Among the two, only the video resolution&datarate
differ. Audio format&rate is the same.
All is working fine. However, it seems there is redundancy in the audi

Hi Marton,
The suggested options fixed the sync issue in a snap.
Thank you, thank you, thank you!!

Hi,
On Win7 x64, Capturing SDI from DeckLink Duo 2.
When encoding with FFmpeg, audio seems to be about 100ms later than
video. Is there a known solution to this, or is there a way to delay
video by roughly 100ms?
Below is the command & output when using NVENC and streaming UDP, but

Why do you need to make interlaced from progressive?
Excuse me to jump in.
For example, when encoding for BD I need to make the choice between
1080i to retain resolution, or 720p for ease of handling.

Please excuse me for posting what may be a question on containers in

How difficult is it to modify FFmpeg to enable HEVC output over RTMP?

Hi,
Trying to build a real-time transcoding farm based on FFmpeg + NVENC.
I see many bench marks report on encoding frame rate, but not sure on
how they scale when the number of encoding processes increase.
I would appreciate advise from those with insight on the following.
