Hi Folks, I'm trying to resize an mp4 file using ffmpeg, but the output file comes out empty. I see the following messages just before the command finishes: Truncating packet of size 103333 to 101557 time=00:00:06.10 bitrate= 585.7kbits/s [h264 @ 0x20646aa0] AVC: nal size 103329 Last message repeated 1 times [h264 @ 0x20646aa0] no frame! [mov,mp4,m4a,3gp,3g2,mj2 @ 0x1ff19240] stream 0, offset 0x200ed8: partial file /data/sftp/video/temp/video_promo/764556_4_p.mp4: Invalid data found when processing input Any pointers on how to track down what's causing this? You can see the full output of the command below, followed by the output of ffprobe. The only alterations are a few pieces of sensitive data that I've removed which shouldn't have any bearing on diagnosing the issue.
