  • Sync issue for some videos, when using MediaCodec with FFMPEG

    11 novembre 2015, par 123rgt

    I’m using FFMpeg to get the packets from video, and MediaCodec for hw decoding the video. I’m using pkt->pts value for sync. But for the videos with pkt->pts==AV_NOPTS_VALUE, the sync fails. I can’t use av_frame_get_best_effort_timestamp since the packet is directly decoded and rendered to surface by MediaCodec. What can I do for correct this sync issue ?

  • FFMPEG joining multiple videos in grid

    31 mars 2020, par Adam Gosztolai

    I am trying to join a series of videos in a grid. Here is a command I used for 3 videos.

    ffmpeg -y -i /mnt/labserver/vid1.mp4 -i /mnt/labserver/vid2.mp4 -i /mnt/labserver/vid3.mp4 -filter_complex "color=s=360x360:c=Black [nbase];[0:v]setpts=PTS-STARTPTS,scale=180x180[b0];[1:v]setpts=PTS-STARTPTS,scale=180x180[b1];[nbase][b0]overlay=shortest=1:x=0:y=180[temp0];[temp0][b1]overlay=repeatlast=1:x=0:y=360[temp1];[temp1][b2]overlay=repeatlast=1:x=0:y=540[temp2]" -c:v libx264 -pix_fmt yuv420p /mnt/labserver/videos_joined.mp4

    I get the following error

    Invalid stream specifier: b2

    As far as I recall this has previously worked for me. Could someone tell me what could be wrong here and whether perhaps the error depends on the FFmpeg version ?

    Thank you !!
