    My case is very similar to

    Converting a call center recording to something useful

    in this link, he can fix by using Goldwave for converting file. I also tried Goldwave too but still didn’t work.

    So, Do I have to config more with Goldwave or any solution at least I want to listen to it

    I use MacOs but don’t mind if have to use window for open it.

    Ps. can listen sample audio in the link (my recoding is the same as the sample in this link)

  • FFmpeg android video processing does not return error message

    25 août 2018, par Дмитрий Мельчин

    friends. I am creating a program that puts the sound and picture to video. I’m using the ffmpeg library https://github.com/bravobit/FFmpeg-Android.
    The command looks like this :

    String command = "-i /data/user/0/com.radpony.vhs.camcorder/files/RADVHS/camcorder_video.mp4 -i /data/user/0/com.radpony.vhs.camcorder/files/RADVHS/watermark_png.png -i /data/user/0/com.radpony.vhs.camcorder/files/RADVHS/playarrow.png -filter_complex [0]crop=720:720[croped];[1]scale=w=143:h=50[tmp];[croped][tmp]overlay=x=577:y=10[overlayed];[overlayed][2]overlay=x=150:y=10[overlayed2];[overlayed2]drawtext=fontfile=/data/user/0/com.radpony.vhs.camcorder/cache/VCR_OSD_MONO_1_001.ttf:text='PM 11\:06Aug..25 2018':fontcolor=white:fontsize=48:x=50:y=600[withdate];[withdate]drawtext=fontfile=/data/user/0/com.radpony.vhs.camcorder/cache/VCR_OSD_MONO_1_001.ttf:text='Play':fontcolor=white:fontsize=48:x=50:y=30 -codec:a copy -c:v libx264 -preset ultrafast /data/user/0/com.radpony.vhs.camcorder/files/RADVHS/rendered_video.mp4";

    It works great for Android 6, but on the Samsung devices with Android 7 while processing of video ffmpeg just stops without displaying an error message.
    If someone knows the solution to this problem, help, please

  • FFmpeg - Buffer queue overflow, dropping - when combining 2 videos and using concat, hstack and trim

    23 août 2018, par Mayank

    I am trying to merge two videos using concat and hstack but getting buffer overflow error resulting in the one of the video getting paused for few seconds.

    I tried adding fifo and h264 video codec as suggested on this forum but the issue persists.

    Can someone please let me know the issue in this command ? Many thanks in advance.

    ffmpeg -i 1_a.opus -i 2_a.opus -i 1_v.mp4 -i 2_v_bars.mp4 -filter_complex "[1:a]adelay=15720|15720[a1]; [0:a][a1]amix; [3:v]trim=0:15.81,geq=0:128:128,fifo [silence]; [silence][3:v]concat,fifo [3_v_silence]; [3_v_silence][2:v]hstack,fifo" -vcodec libx264 -strict experimental -y out_fifo_h264_2.mp4
