  • Cannot convert from mts (AVCHD) to mkv using ffmpeg

    10 August 2016, by waran

    I was trying to convert a .MTS file from my camcorder (Panasonic HC-V700) to a .mkv file (because my editing software does not support MTS). I used the following command:

    ffmpeg -i 00000.MTS -scodec copy -acodec copy -vcodec copy -f matroska 00000.mkv

    But instead of getting a mkv file I get this:

    Any ideas why is it not working? (I am on Kubuntu 16.04 and I have ffmpeg version 2.8.6-1ubuntu2.)

    Edit:

    I tried the command without the subtitle stream (ffmpeg -i 00000.MTS -c copy -sn 00000.mkv), conversion failed again:

    Edit: Temporary solution

    I have found out, that converting to mp4 (fmpeg -i 00000.MTS -c copy -sn 00000.mp4) works. This does not solve the issue, but I can use the mp4 format in my editing software as well.

  • How do I improve the quality of a video produced from still PNG images?

    9 April 2012, by cormullion

    I'm trying to create a video from a few hundred PNG images. The PNG images look OK to me, e.g. here are two in MacOS X Preview:

    two images

    They're about 1200 pixels square, 16 bit RGB, no transparency.

    But my attempt to make a few hundred of these into a video is encountering the following problem - nearly every frame has this yellow corruption (artefacts?), that sort of blocky flickery stuff you see on poor quality videos:

    video still

    The ffmpeg command I'm using is something like this:

    ffmpeg -f image2 -i /tmp/image-%07d.png -vcodec mpeg4 -vb 20M -r 20 poincare.mov

    I've tried changing a few parameters, but I probably changed the wrong ones. Any idea which parameters I should be changing, and to what value?

    Console output is:

     ffmpeg -f image2 -i /tmp/image-%07d.png -vcodec mpeg4 -vb 30M -r 30 poincare.mov

  • FFMpeg Android Stagefright SIGSEGV error (h264 decode)

    19 April 2013, by Sergey Ochkur

    I need to decode h264 file to YUV on Android 2.3+. As I understand I need to communicate with Stagefright, as it`s the only way now, after closing access with OpenMAX IL implementations. I have used FFmpeg 0.10 (and tried 0.9/0.9.1..) for this issue, compiled it with NDK7 (and also tried NDK6b with the same result):

    So, entering next command give me error with 480p:

    Android-developers, does anybody know what this error means and how to deal with it?
    I tried to make DSP window bigger, but with no luck.
    Commands like "stagefright /sdcard/Video/480p.mp4" works fine.

    P.S. Additionally I found that on some bigger files (720p) Android answers next:
