  • How to stitch(concat) two transport stream with two different resolution and I-frame slices format without loosing resolution and slices information

    2 octobre 2019, par ART

    I have been trying to test a use case with steam captured from multimedia device and that didn't work. And then I have been trying to create this specific transport stream for like two days now without success, so requesting some help.

    



    I need to create transport stream with two different resolution and two different slicing format.

    



    I divided the task in following steps and in last two steps I need help.

    



    Step 1 : Download sample video with resolution : 1920x1080.
    
 I downloaded big buck bunny mp4 .

    



    Step 2 : Create transport stream with following
    
resolution : 1920x720, H264 I frame slices per frame : 1
    
I used following ffmpeg commands to do that.

    



    #Rename file to input.mp4
$ mv bbb_sunflower_1080p_30fps_normal.mp4 input.mp4
#Extract transport stream
$ ffmpeg -i input.mp4 -c copy first.ts


    



    first.ts is having 1980x720 resolution and one H264 I slice per frame.

    



    Step 3 : Create another transport stream with smaller resolution using following commands

    



    #Get mp4 with lower resolution.
$ ffmpeg -i input.mp4 -s 640x480 temp.mp4
#Extract trans port stream from mp4
$ ffmpeg -i temp.mp4 -c copy low_r.ts


    



    Step 4 : Edit(and re-encode ?) low_r.ts to have two H264 I frame slices.
I used following command to achieve it.

    



    $ x264 --slices 4 low_r.ts -o second.ts


    



    However when I play this second.ts on vlc using following command it doesn't play

    



    $ vlc ./second.ts 


    



    And using Elacard StreamEye software when I analyze the transport stream I see that it has 4 H264 I slices in only two times other than that lot of H264 p slices and H264 B slices. 
Need help here to figure out why second.ts doesn't play and why slicing is not correct.

    



    Step 5 : Combine both the transport stream without loosing resolution and slicing information.
Don't know command for this. Need help here.
I tried ffmpeg but that combines two stream with different resolution and makes one file with one resolution.

    



    Any suggestions/pointers would help me proceed. Let me also know if any of the above steps are not fine too.
