[FFmpeg-user] Input from FIFO for Multiple Video Track

Thu Jul 12 16:46:07 EEST 2018

Hi All,

I am creating Dual H264 Video Track inside Single MP4 File. For that I am
using following command.

   - *ffmpeg -i fifo_1.264  -i fifo_2.264 -map 0 -map 1 -c copy -t 20
   output.mp4 *

Command is working properly and Its Generating MP4 video with Two H264
Video Track.

But when I am seeing this video in VLC or FFPLAY, I can see Video Frame
Skipping. I can verify frame skipping by using Timer in generated video.
Timer in Video skipping frames from 6th Second to 11 Second.

Can Someone suggest me what I am doing wrong.

Please find attached logs. It may help.

*Thanks & Regards,*
*Axit Soni*
