How to detect anamorphic video with FFProbe ?
29 mai 2015, par FlavorScapeThis is the output I get using FFProbe for a video I’m certain is anamorphic. I’ve converted it as a test with ffmpeg and the results are consistent with the video having a different PAR and DAR (video is squished). I ran some command line params to fix anamorphic video and it worked. Possibly my diagnosis is incorrect, the PAR and DAR are just plain wrong ?
The code I used to "correct" the anamamorphic is
--custom-anamorphic --display-width 1280 --keep-display-aspect --modulus 8 --crop 0:0:0:0Is there an additional command with FFProbe to detect for anamorphic ? So far I’m just seeing if the sample_aspect_ratio and display_aspect_ratio are the same or not.
Additionally, a ratio of 0:1 seems incorrect. My video is not infinitely wide. Is there a bug with FFProbe output ?
This is the command

ffmpeg frame rate issue h264+ass to mkv
27 juin 2013, par user2529661I'm using this command for ffmpeg :
ffmpeg -i 1.h264 -i ass1.ass -map 0 -map 1 -c copy test.mkvThe h264 file is 30 fps... the mkv plays at 25fps so it runs slow
The h264 come off my hd webcam. If i change the frame rate on the camera to 25 it works fine and 15fps wilk play at high speed. I can force the frame rate ? Every if i need a different command line tool to change it that is acceptable. But if i could fix it form ffmpeg that would be ideal. I'm running the commands from vb.net.
command output
C:\Record\Normal\2013-06-27>c:\ffmpeg\bin\ffmpeg -i 1.h264 -i ass1.ass -map 0 -
