mp4 goes fine with the following output: Input #0, concat, from 'ffconcat-jpeg.txt':ĭuration: 00:08:25.00, start: 0.000000, bitrate: 0 kb/s Initial attempts generated 100s of warnings, but with some arguments added, I reduced it down to just a handful, but this handful is stubborn and nothing I tried would help. The above does produce a reasonable output - it plays first video, then plays second video with no timing/rate issues AFAICT, then plays JPEGs with time between each JPEG "frame" growing successively, as expected.īut, the conversion process produces warnings that concern me (for compatibility with players or potentially other IRL streams that may result in some issue my prototyping content doesn't make obvious). echo "ffconcat version 1.0" >ffconcat-h264.txtĮcho "file low-motion-video.mp4" >ffconcat-h264.txtĮcho "file full-video.mp4" >ffconcat-h264.txtĮcho "file video-jpeg.mp4" >ffconcat-h264.txt Stitch all together by generating another concat directive file.

stream1.h264 + ')Ĭonvert two streams from.

By variably-spaced I mean where elapsed time between any two adjacent JPEGs may (and likely to be) different from any other two adjacent JPEGs. I have a process flow that may output either H.264 Annex B streams, variably-spaced JPEGs, or a mixture of two.
