  • x264 on Ubuntu video bad/corrupted

    6 septembre 2013, par Ryzone

    I am trying to use command line x264 to produce a blu-ray compatible file for use in Adobe Encore. For the source file I've tried both ProRes and mpeg2, both 1080p24. Both files import into Encore fine (no transcoding needed which is great) but the ProRes version is pink and grey "static" and the mpeg2 is just a bunch of green/black lines. The exact same files and the exact same commands on my Win7 PC come out fine. I'm only doing a 10 sec sample of the complete 90min movie. I'd love for it to work on Ubuntu cause it is running a new i7 haswell that encodes much quicker than my PC (many hours difference in encoding time)

    Ubuntu 13.04
    

    
x264 0.135.2 f0c1c53<br />
    
built on Jul 24 2013, gcc: 4.7.3<br />
    
configuration: --bit-depth=8 --chroma-format=all<br />
    
x264 license: GPL version 2 or later
    

    
command:
    
    x264 --bitrate 30000 --preset veryslow --tune film --bluray-compat --fps 24000/1001 --force-cfr --bframes 3 --ref 4 --muxer raw --no-weightb --weightp 0 --b-pyramid none --vbv-maxrate 40000 --vbv-bufsize 30000 --level 4.1 --profile high --keyint 24 --min-keyint 1 --open-gop --slices 4 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1  -o output.264 --input-res 1920x1080 sample.mov

    (if it would work I'd be doing two pass encoding)

    I am able to encode the sample file with ffmpeg to h264 (if that helps).

  • how to debug a corrupted video file with ffmpeg ?

    12 janvier 2018, par Blurry Script

    for example I downloaded some film, it is somehow encoded with some program, when I try to use ffmpeg to convert it, let’s say from mkv to mp4, i get an error that :

    [matroska,webm @ 0x1d06640] Read error at pos. 2241497 (0x2233d9)

    now how can I know where is the reason that this happens ? should just avoid this kind of files, or somehow debug it and see what is the reason behind this error ? or maybe skip this error frames, but i dont know how many frames may be like this, what if most of the file is filled with corrupted frames, altough it is playable in the video player

  • ffmpeg error convertimg mkv to mp4

    11 janvier 2018, par Blurry Script

    I do this :

     ffmpeg -i "film.mkv" -strict experimental film.mp4

    I get this :

    [matroska,webm @ 0x29fb0e0] Read error at pos. 93417 (0x16ce9)

    the file itself is playable and ok, but how can I fix this ? or at least see the reason why it is reporting this, any clues ?
