  • ffmpeg copy video in video with a specific time

    13 février 2017, par Alkl

    Im new in this topic (beginner) and Im german... So it’s a bit difficult to find the correct words...

    I’ll try to explain what I’ve done and what I want to do :

    1. Extract video area from the original video converted in PRORES codec :

      ffmpeg.exe -i test.mkv -ss 00:06:21.99 -t 00:00:01.94 -async 1 -strict -2 -c:v prores_ks -pix_fmt yuva444p10le -profile:v 4444 -bits_per_mb 8000 -s 1920x1080 cut_video.mov

    2. Edit the cut in After Effects

    3. Convert the PRORES in Matroska

      ffmpeg.exe -i "C :\Users\Alex\Desktop\ffmpeg-20170202-08b0981-win64-static\bin\cut_video\cut_video.mov" -vcodec ffv1 -acodec pcm_s16le temp.mkv

    4. Replace the video area in the originale video file at the time 00:06:21.99...

    I spend 4 hours for the two commands...
    So I despair at the fourth step. Is it possible ? Can you help me ?

    I made a picture, so you can understand better what Im doing... : http://i.imgur.com/HqlNxzW.jpg

    Best regards from germany,

  • Looking for video libraries for editing video on windows/ios/azure service [on hold]

    17 juillet 2015, par sanyam

    Which library would be a good bet in terms of ...
    1. Richness in features (I want to create a video from short clips and images with effects and filters). Think auto videos created from Google Photos.
    2. Extensibility - I would prefer using similar tech on IOS and Windows apps. Might have to offload some processing to a web service on Azure (windows or linux).
    3. Programmability - An API is preferred over command line as it gives more flexibility and better error handling.

    Given all these options, what is my best bet ? I’ve only looked at ffmpeg till now, is there a better alternative ?

  • playback of ffmpeg converted video on LDPI device (Samsung S5300 240 x 320)

    25 décembre 2013, par user737486

    I have Full HD video taken by Samsung Galaxy S4 camera.
    video stream info as follows :

    {"index":0,"codec_name":"h264","codec_long_name":"H.264 \/ AVC \/ MPEG-4 AVC \/ MPEG-4 part 10","profile":"High","codec_type":"video","codec_time_base":"1\/180000","codec_tag_string":"avc1","codec_tag":"0x31637661","width":1920,"height":1080,"has_b_frames":0,"sample_aspect_ratio":"0:1","display_aspect_ratio":"0:1","pix_fmt":"yuv420p","level":40,"r_frame_rate":"30\/1","avg_frame_rate":"21240000\/707831","time_base":"1\/90000","start_pts":0,"start_time":"0.000000","duration_ts":1415662,"duration":"15.729578","bit_rate":"16553536","nb_frames":"472","disposition":{"default":1,"dub":0,"original":0,"comment":0,"lyrics":0,"karaoke":0,"forced":0,"hearing_impaired":0,"visual_impaired":0,"clean_effects":0,"attached_pic":0},"tags":{"rotate":"90","creation_time":"2013-12-24 10:19:18","language":"eng","handler_name":"VideoHandle"}}

    in short it is 1920x1080, 16KK bitrate, rotation : 90.
    I'm converting it using ffmpeg by the following command :

    ffmpeg -y -threads 8 -i input.mp4 -vcodec libx264 -vpre ipod640 -s 324x576 -strict -2 -b:v 512k -acodec aac -ac 1 -ar 16000 -ab 32000 -vf "transpose=1" -metadata:s:v:0 rotate=0  output.mp4

    The output video stream info :

     {"index":0,"codec_name":"h264","codec_long_name":"H.264 \/ AVC \/ MPEG-4 AVC \/ MPEG-4 part 10","profile":"Constrained Baseline","codec_type":"video","codec_time_base":"1\/48","codec_tag_string":"avc1","codec_tag":"0x31637661","width":324,"height":576,"has_b_frames":0,"sample_aspect_ratio":"0:1","display_aspect_ratio":"0:1","pix_fmt":"yuv420p","level":30,"r_frame_rate":"24\/1","avg_frame_rate":"24\/1","time_base":"1\/12288","start_pts":0,"start_time":"0.000000","duration_ts":72192,"duration":"5.875000","bit_rate":"521597","nb_frames":"141","disposition":{"default":1,"dub":0,"original":0,"comment":0,"lyrics":0,"karaoke":0,"forced":0,"hearing_impaired":0,"visual_impaired":0,"clean_effects":0,"attached_pic":0},"tags":{"language":"eng","handler_name":"VideoHandler"}}

    The output video being played without any problem, on many different devices and OSes including different iOs and androids, but Samsung S5300 doesn't play it. From the device log I can see the following exception :

    E/AwesomePlayer( 1349): This resolution [324X576] Not Supported

    But, when I change the width and height to 576x324 the video can be played on S5300, but in wrong rotation.
    What should I add in ffmpeg parameters to make it play in correct orientation ?

    ffmpeg version :

    ffmpeg version git-2013-12-22-911676c Copyright (c) 2000-2013 the FFmpeg developers built on Dec 22 2013 22:55:31 with gcc 4.4.5 (Debian 4.4.5-8)

    Thanks
