  • FFMPEG timelapse with alternate time scale

    24 juin 2022, par Bill V

    My home video system takes a snapshot every 15 seconds. At midnight I run a script that uses ffmpeg to create a time lapse video at 8 frames/second. Playing the resulting time lapse video takes 12 minutes. When I play it back, the time line show the time as 0-12:00. I'd like it to show the time of the snapshots - 0-23:59:45. Can that be done and if so how ? Below is the ffmpeg command I use. Prior to running ffmpeg, the images are in files ordered 1.jpg to 5760.jpg. Thanks

    


    ffmpeg -r 8 -s 1920x1080 -i %%d.jpg -vcodec mpeg4 -crf 25 -pix_fmt yuv420p temp.mp4


    


  • DirectShow RTSP SourceFilter with MPEG-4 Video Stream

    20 mars 2021, par Novalis

    I create a simple direct show source filter using FFmpeg.I read rtp packets from RTSP source and give them to decoder. It works for h264 stream.

    



    MyRtspSourceFilter[H264 Stream] ---> h264 Decoder --> Video Renderer


    



    The bad news is that it does not work for MPEG-4. I can able to connect my rtsp source filter with MPEG-Decoder. I got no exception but video renderer does not show anything. Actually just show one frame then nothing [just stop]... Decoders and Renderers are 3rd party so i can not debug them.

    



    MyRtspSourceFilter[MP4 Stream] ---> MPEG-4 Decoder --> Video Renderer


    



    I can able to get rtp packets from MPEG-4 RTSP Source using FFmpeg sucessfully.There is no problem with it.

    



    


    It seems that i have not set something(?) in my Rtsps Source
 Filter which is not necessary for H264 stream but may be important for
 MPEG-4 stream

    


    



    What may cause this h264 stream and MPEG-4 stream difference in a direct show rtsp source filter ? Any ideas.

    



    More Info :

    



    — First i try some other rtsp source filters for MPEG-4 Stream...Although my rtsp source is same i see different subtypes in their pin connections.

    



    — Secondly i realy get suspicious if the source is really MPEG-4 SO i check with FFmpeg...FFmpeg gives the source codec id as "CODEC_ID_MPEG4".

    



    Update : 
[ Hack ]

    



    I just set m_bmpInfo.biCompression = DWORD('xvid') it just worked fine...But it is static. How to dynamically get/determine this value using ffmpeg or other ways...
