ffmpeg converting video to images while video file is being written
15 October 2015, by user3398227Hopefully an easy question for an ffmpeg expert!
I’m currently converting large (+6GB) mpeg video into an image sequence - which is working well using the below ffmpeg command:
ffmpeg -i "input.mpeg" -vf - fps=fps=2 -f image2 -qscale 1 -s 1026x768 "output%6d.jpg"
however i have to wait for the file to finish being written to disk before i kick off ffmpeg - but this takes a good hour or so to finish writing, but what i’ve noticed is that ffmpeg can start reading the file while its being written to disk - the only snag here is it gets to the end of the file and stops before the file has finished being written...
Question is, is there a way that ffmpeg can convert to an image sequence at the same pace the video is being written (and not exit out?)... or know to wait for the next frame to be written from the source. (unfortunately the input doesn’t support streaming, I only get a network drive and file to work off.. ) I thought i read somewhere that ffmpeg can process at the video frame rate but cant seem to find this command for love or money in the doco!!
Thanks!

How to handle queueing of video encoding during multiple video uploads?
6 March 2016, by Yash DesaiI am working on developing a video streaming site where users can upload videos to the site (multiple videos at once using the uploadify jquery plugin).
Now, I am faced with the question of encoding the videos to FLV for streaming them online.
When should the video encoding process take place ? Should it take place immediately after uploads have finished (i.e redirect the user to upload success page, and then start encoding in the background using exec command for ffmpeg ?) However, using this approach, how do i determine if the encoding has finished successfully ? What if users upload a corrupt video and ffmpeg fails to encode it ? How do i handle this in PHP ?
How do i queue encoding of videos since multiple users can upload videos at the same ? Does FFMpeg has its own encoding queue ?
I also read about gearman and message queueing options such as redis and AMQP in another related SO thread. Are these one of the potential solutions ?
I would really appreciate if someone could give answers to my questions.
