ffmpeg_preview_options
by Legault, Phillip [GTSUS] 24 Nov '17

24 Nov '17

I'm not fomiluar with ffmpeg at all, and ffmpeg is required for my Digital Asset Management site. I'm having issues with previews on the site and I was told: "The requirement is to generate an MP4 file with 'h264' video encoding and 'AAC' audio for web browser playback. If we can ascertain the ffmpeg command required for this we can add it. For my own system the option I use is as below:- $ffmpeg_preview_options=" -c:v libx264 -pix_fmt yuv420p -crf 23 -preset fast -maxrate 4000k -bufsize 1835k -strict -2"; We advise testing the command from the server using a test source file until you find the correct settings. Once you have this you can update the configuration accordingly. " I have no idea on how to test this or find the correct syntax to allow the generation of previews. I would appreciate any help you can provide me. Thank you, Phil

Bit Depth of PNG Overlay with Alpha channel
by Pete Willis 24 Nov '17

24 Nov '17

We have a transparent PNG file with a drop shadow. The drop shadow when overlayed onto a Mov is rendering very dark. Comparing the same file in an NLE (Premiere Pro) the drop shadow opacity is showing as much lighter. I believe the problem is that the NLE is using 32bit colour depth where as FFMPEG is using 8bit colour depth. Is there a way to specify the colour depth of the overlay or the png? The param we are using is -filter_complex 'overlay' Thanks The information contained in this transmission may be confidential.

rtsp mpegts stream not captured with ffplay

Hi, I have a strange problem with rtstp and mpegts streams from a VOD provider. The <url> is rtsp://<server>:554/<stream>.ts The stream does play fine with vlc, but not with ffplay and ffmpeg does not work properly either.

Hello, I'm pretty new to video processing and I came across this usuful tool. Using the info I found on the following page I created a mosaic using four mp4 files (original frame rate is 60 fps). Create a mosaic out of several input videos – FFmpeg | | | | | | | | | | | Create a mosaic out of several input videos – FFmpeg | | | The output looks fine but has only 25 fps instead of 60.I'd like to have an output with the same video quality and frame rate of original. I tryed to add option -crf 0 but it seems doesn't work. -c:v libx264 -crf 0 output.mp4 What could be the correct settings? Best regards

MXF AS-07 Guidlines
by michael gates 23 Nov '17

23 Nov '17

Hello, I was curious about any current or future plans to accept and integrate the new AS-07 standard for MXF Archive and Preservation. (Found at the link below: http://www.digitizationguidelines.gov/guidelines/MXF_app_spec.html Specifications: http://www.digitizationguidelines.gov/guidelines/AS-07_20170908.pdf) I have run their test files through a few tests, and was just curious what ffmpeg's approach to the MXF wrapper according to the AS-07 guidelines is going to be. Kind regards, -- *Mike Gates*

remap filter gives only black and white output
by Michael Koch 23 Nov '17

23 Nov '17

I've written a C# program to create my own xmap and ymap files for the remap filter. The geometric distortion in the output video looks as expected. But why is the output only black and white? I've tested two different input videos with the same result. No colors in the output. The console output is attached below.
