[FFmpeg-user] PhotoJPEG File doesn't playback properly on Quicktime 7

[Patrick Cusack]

>> I wouldn’t know if this is an ffmpeg or Quicktime 7 issue, but I am encountering  playback stutter on Quicktime 7 when playing back photo-jpeg encoded files. I don’t encounter this issue in Quicktime X or with other players. I only bring this up so I can verify that I am not missing anything. I am using the following example:
>> 
>> ffmpeg -i moviefile.mov -c:v mjpeg -pix_fmt yuv420p output.mov
>> 
>> How would you recommend I further diagnose this issue?

> please post the complete/unedited command output to the list (see https://ffmpeg.org/mailing-list-faq.html)

I have attached my command line. Again these files only stutter in Quicktime 7. Should this be a QT7 issue, then fine, but I would like to know any possibility that would cause this.

Thanks
