Affectiva drops every second frame
19 juin 2019, par machineryI am running Affectiva SDK 4.0 on a GoPro video recording. I’m using a C++ program on Ubuntu 16.04. The GoPro video was recorded with 60 fps. The problem is that Affectiva only provides results for around half of the frames (i.e. 30 fps). If I look at the timestamps provided by Affectiva, the last timestamp matches the video duration, that means Affectiva somehow skips around every second frame.
Before running Affectiva I was running ffmpeg with the following command to make sure that the video has a constant frame rate of 60 fps :
ffmpeg -i in.MP4 -vf -y -vcodec libx264 -preset medium -r 60 -map_metadata 0:g -strict -2 out.MP4 null 2>&1When I inspect the presentation timestamp using
ffprobe -show_entries frame=pict_type,pkt_pts_time -of csv -select_streams v in.MP4I’m getting for the raw video the following values :Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/media/GoPro_concat/GoPro_concat.MP4':

If I run Affectiva on the raw video (not processed by ffmpeg) I face the same problem of dropped frames. I was using Affectiva with
affdex::VideoDetector detector(60);Is there a problem with the ffmpeg command or with Affectiva ?
Edit : I think I have found out where the problem could be. It seems that Affectiva is not processing the whole video but just stops after a certain amount of processed frames without any error message. Below I have posted the C++ code I’m using. In the
onProcessingFinished()method I’m printing something to the console when the processing is finished. But this message is never printed, so Affectiva never comes to the end.Is there something wrong with my code or should I encode the videos into another format than MP4 ?

affdex::VideoDetector detector(60, 1, affdex::FaceDetectorMode::SMALL_FACES);on that raw video the following file is produced. Affectiva stops after 906s without any error message and without printing "[Affectiva] Video processing finised".When I now transform the video using
ffmpeg -i raw.MP4 -y -vcodec libx264 -preset medium -r 60 -map_metadata 0:g -strict -2 out.MP4and then run Affectiva withaffdex::VideoDetector detector(60, 1, affdex::FaceDetectorMode::SMALL_FACES);, Affectiva runs until the end and prints
"[Affectiva] Video processing finised" but the frame rate is only at 23 fps. Here is the file.When I now run Affectiva with
affdex::VideoDetector detector(62, 1, affdex::FaceDetectorMode::SMALL_FACES);on this transformed file, Affectiva stops after 509s and "[Affectiva] Video processing finised" is not printed. Here is the file. -
Avisynth total frames does not equal VirtualDub total frames
7 mai 2017, par CorpuscularIt appears that Dissolve and/or Fade change the total number of frames in .avs scripts. When I add up the total number of frames in the avs script and then load the avs script in Vdub the total number of frames is different. My real world example below shows a difference of 822 frames vs 1368 frames for the same script. I have run some basic tests which appear to support this hypothesis. Of course I may be doing something stupid. Any guidance would be greatly appreciated. Please let me know if I can clarify anything. Ffmpeg also borks on the same script which leads me to think this is an Avisynth issue. Or my lack of avs coding skills.
