When appending videos, you usually need to match the specs for the video, including dimensions, framerate, pixel format
filtered.mp4 is 640x352, 30fps intro.mp4 is 1080x608, 59.94fps My guess is that is part of the reason. The specs can change midstream for a transport stream, but some players , decoders might have problems with it. MP4 container does not support changes midstream as well as transport streams The aspect ratio is slightly different between them. 1.818 vs. 1.776. You'd have to letterbox the filtered version if converting that up; or if you didn't care about the AR error, then just resize it -- Sent from: http://www.ffmpeg-archive.org/ _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
