    FinalOutput.mpeg has the same frames as output.mpeg
    I have several TransportStreams to process and everyone has a frame difference

    someone can help me to solve the problem ?

    I need FinalOutput.mpeg to be aligned frame by frame with the original and necessarily the video must impress the timecode.

    a possible solution would also be a replace "damaged" frame but I can not find out how to replace the skipped frames

    EDIT :

    i’ve tried to work from OriginalVideo.ts and extracted video with -map directly with FFMPEG but the result is the same

    CL : ffmpeg -i OriginalVideo.ts -map 0:0 -c:v copy output.h264

  • Converting .3gp file into mp4 file in android using ffmpeg

    8 août 2013, par user2171513

    I want to convert .3gp file into .mp4 file with resolution modified in Android using ffmpeg.
    I want to increase the resolution of the video from its standard resolution to 1920x1080.

    So far I have been successful in
    1) extracting .h264 video file from .3gp file and increase its resolution
    2) extracting .aac audio file from .3gp file.

    Now I want to combine them back into .mp4 file. The commands that I have used to extract this .h264 and .aac files are :

    ./ffmpeg -i 1.3gp -vbsf h264_mp4toannexb -s 1920x1080 1.h264
    
./ffmpeg -i 1.3gp -ab 160k -ac 2 -ar 48000 -vn -strict -2  1.aac

    The command that I have tried to merge them back is

    ./ffmpeg -i 1.h264 -i 1.aac -map 0:0 -map 1:0 -strict -2 1.mp4

    The 1.mp4 that gets generated at the end basically has audio only at few sync frames of video. (Thats what I feel , because the audio is present at specific intervals within the video)

    Can anyone please help in figuring out what am I missing here.

    EDIT :
    So basically I want to concat 4 different videos of 4 different resolution and type.

    1)

    ./ffmpeg -i 1.mp4 
    
Video: h264 (High), yuv420p, 1920x1080, 16959 kb/s, 29.85 fps, 90k tbr, 90k tbn, 180k tbc
    
Audio: aac, 48000 Hz, stereo, s16, 106 kb/s

    2)

    ffmpeg -i 2.mp4
    
Video: h264 (Constrained Baseline), yuv420p, 640x480, 3102 kb/s, 29.99 fps, 90k tbr, 90k tbn, 180k tbc
    
Audio: aac, 48000 Hz, stereo, s16, 93 kb/s

    3)

    ffmpeg -i 3.3gp
    
Video: h263, yuv420p, 1408x1152 [PAR 12:11 DAR 4:3], 2920 kb/s, 15 fps, 15 tbr, 15360 tbn, 29.97 tbc
    
Audio: amrnb, 8000 Hz, 1 channels, flt, 12 kb/s

    4)

    ffmpeg -i 4.3gp
    
Video: h264 (High), yuv420p, 352x288 [PAR 12:11 DAR 4:3], 216 kb/s, 24 fps, 24 tbr, 24 tbn, 48 tbc
    
Audio: aac, 44100 Hz, stereo, s16, 92 kb/s

    So I am converting them to mpegts using following commands

    ./ffmpeg -i 1.mp4 -c:v libx264 -vf scale=1920:1080 -r 60 -c:a aac -ar 48000 -b:a 160k -strict experimental -f mpegts 1.ts
    
./ffmpeg -i 2.mp4 -c:v libx264 -vf scale=1920:1080 -r 60 -c:a aac -ar 48000 -b:a 160k -strict experimental -f mpegts 2.ts
    
./ffmpeg -i 3.3gp -c:v libx264 -vf scale=1920:1080 -r 60 -c:a aac -ar 48000 -b:a 160k -strict experimental -f mpegts 3.ts
    
./ffmpeg -i 4.3gp -c:v libx264 -vf scale=1920:1080 -r 60 -c:a aac -ar 48000 -b:a 160k -strict experimental -f mpegts 4.ts

    then concatenating the .ts files into f.ts and then creating a final .mp4 file from it using

     cat 1.ts 2.ts 3.ts 4.ts > f.ts
    
./ffmpeg -i f.ts -c copy -bsf:a aac_adtstoasc output.mp4

    But my f.ts also doesnt seem to play correctly in VLC on linux, it plays first 2 mp4's video + audio and it plays last .3gp's audio only.(Same for output.mp4 too) Could you please help me in figuring out what am I missing ?

    Thanks

  • Tools/Techniques for investigating video corruption — ffmpeg / libavcodec

    17 juillet 2013, par Gopherkhan

    In my current work I'm trying to encode some images to h264 video using the FFMPEG's C library. The resulting video plays fine in VLC, but has no preview image. The video can play in VLC and Mplayer on ubuntu, but won't play on Mac or PC (in fact, it causes a "VTDecoderXPCService quit unexpectedly" error on Mac).

    If I run the resulting file through FFMPEG using the command line, the resulting file has a preview image, and plays correctly everywhere.

    Apparently the file that I get out of the program is corrupt in some weird place, but I don't have any output during my compilation or run to indicate where. I can't share my code at the moment (work code isn't open source yet :-( ), but I have tried a number of things :

    1. Writing only header and trailer data (av_write_trailer) and no frames
    2. writing frames only minus the trailer (using avcodec_encode_video2 and av_write_frame)
    3. Adjusting our time_base and frame pts values to encode only one frame per second
    4. Removing all variable frame rate code
    5. Numerous other variants that I won't bother you with here

    In creating my project, I've also followed the following tutorials :

    And consulted the deprecated ffmpeg functions list

    And compiled FFMPEG on ubuntu according to the official doc

    And consulted numerous StackOverflow questions :

    But every run of the program runs into the exact same problem.

    My question is, is there anything obvious that causes a programmatic run of FFMpeg to differ from a console run (e.g., an incomplete finalization, some threading issues, etc.) ? Like some obvious reason that a console run could repair a corrupted file ? Or is there a decent tool/method for inspecting a video file and finding the point of corruption ?
