 @section h264_mp4toannexb
 
+Convert an H.264 bitstream from length prefixed mode to start code
+prefixed mode (defined in Annex B of the ITU-T H.264 specification).
+
+This is required by some streaming formats, for example the MPEG-2
+transport stream format ("mpegts").
+
+For example to remux an MP4 file containing an H.264 stream to mpegts
+format with @command{ffmpeg}, you can use the command:

+ at example
+ffmpeg -i INPUT.mp4 -codec copy -bsf:v h264_mp4toannexb OUTPUT.ts
