After discussing with support within the #ffmpeg IRC channel, this approach
doesn't seem to be too reliable or consistent to keep track of frame count
from sender and receiver. A "frame" in ffmpeg at the decoding side is just
"however many samples the decoder decoded from one packet". The thing

Ideally I would like to have both: out_range=unity and out_range=r103.
This would be the most flexible.

Alternatively you could have out_range=r103. The risk here is that EBU

We already have:

Why not have out_range=unity which does not alter the video levels at all?

"FFmpeg's v210 encoder surprisingly limits the video levels, if you

Thanks for the direct answer. That makes ffmpeg useless for my purposes.
It would be nice if ffmpeg had an option to defeat this behavior. i.e. "unity
gain".

I know about full- (0 - 255) and limited- (16 - 235) range video. I am working

Could you please double-check whether the file is present in that path
"C:\Users\alfes\Videos\mm.mp4". Also, share your console output.

Hashing for fixity and transfer-checking seems to be quite a bottleneck
for archiving big video/film files for archiving.
Therefore I was considering if using "simpler" algorithms (like CRC
instead of SHA256) could speed up the process.
I was surprised that e.g. MD5 vs CRC in

Hello,
Any suggestion will be a great help for the below detailed problem:
I am using ffmpeg to record an ip camera stream.
The camera produces variable frame rate stream.
I am using an SDP file to capture the stream, and save it in files
containing data of of 5 mins.
OS used is centOS 6.6
Also consider the fact that there’s going to be at least the minimum of
container header and muxing overhead.

Hi
While encoding a video file using FFmpeg we have option to handle thread
parameter. I used Quad Core Processor and find below my observations.
*Case 1: Default thread usage*
By default if we didn't specify thread value FFmpeg internally adjusts
thread count usage based on the core

Hello,
I am looking for someone who could help me set up ffmpeg on a raspberry pi
to run a camera. I would need the camera to take a picture at specific
times throughout the day. Once a photo has been taken, I would like the
image to be added to a timelapse video that shows all the photos that
Hi,
I would like to take an H264+AAC transport stream and send it to a web
page. The easiest way to do this is as WebRTC. Can FFmpeg convert an
H264+AAC transport stream into WebRTC? It seems to be able to convert to
most things, eg MP4, RTMP, etc. But I can't find a webrtc option.
Regards,
Thank you very much for your answers! Every community should be proud to
have such an active and willing to help members. I see that it's not
possible to achieve my goal today the direct way, c’est la vie.

Hi Guys,
I am running ffmpeg (statically linked) in a jailshell of a hosted

Well, you didn't say that. But you are right, as I have just tested with

Thank you for your answer. Now I've tried:
nvidia-smi -g 0 -fdm 1
Return:

All done.

Sorry, but I think that the problem is not in profile M10-1B. This article (
https://support.citrix.com/article/CTX217781) says that we require profile
with equal or more than 1GB to use NVENC, but M10-1B include 1GB, so, it's
ok.
When I use command:
ffmpeg -f gdigrab -i desktop -framerate 30
I found another project that allows me to enable the IV50 codec that comes
with WIndows 10.

Thank you for your reply. I'm working with virtual machine provided on the
basis of Nvidia Tesla M10 with profile that allow to use nvenc, but don't
provide cuda cores. That's why I receive the following.
Command: ffmpeg -f gdigrab -i desktop -framerate 30 -tune zerolatency -r 30
-c:v hevc_nvenc
