This question is also asked on Audio-Video Production
I have some files that when played in jwplayer the playback is corrupt. The files are encoded to h.264 using FFMpeg and there is other files encoded in the same way that works.
At the moment we only use the flash version of the player.
This problem started showing up after we did an upgrade to FFMpeg, so I haven't ruled out that it could be an encoding error.
the command used to run FFMpeg is:
ffmpeg
-i /home/ftp/1c8f08b7d0d9e7fa4b24066156ad50bc981497a0.mov
-vcodec libx264
-preset ultrafast
-profile baseline
-acodec libfaac
-ab 96k
-crf 19
-vf movie="/home/adam/logo.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]"
-y /home/ftp/1c8f08b7d0d9e7fa4b24066156ad50bc981497a0.flv
I am in no way an expert in FFMpeg commandline, so feel free to point out any mistakes made.

A coworker was able to view a "corrupted" file. The only difference between my computer and his is that he have a Mac. Same flash version, same JW Player version. Something is not right here.
Seems like the culprit was the framerate. Through some magic thing the framerate of the resulting video was around 1000. Using -r 30 seems to have solved the issue.
