• Seek issue with ffmpeg

  1er janvier 2015, par Ramesh

  I implemented one audio player using with ffmpeg for playing all format audio files in android.I used following code for seek the song.

           int64_t seekTime = av_rescale_q(seekValue * AV_TIME_BASE,
  
                      AV_TIME_BASE_Q,
  
                      fmt_ctx->streams[seekStreamIndex]->time_base);
  
  
  
              int64_t seekStreamDuration =
  
                      fmt_ctx->streams[seekStreamIndex]->duration;
  
  
  
              int flags = AVSEEK_FLAG_BACKWARD;
  
              if (seekTime > 0 && seekTime < seekStreamDuration)
  
                  flags |= AVSEEK_FLAG_ANY;
  
  
  
              int ret = av_seek_frame(fmt_ctx, seekStreamIndex, seek_target,
  
                      flags);
  
  
  
              if (ret < 0)
  
                  ret = av_seek_frame(fmt_ctx, seekStreamIndex, seekTime,
  
                          flags);
  
  
  
            avcodec_flush_buffers(dec_ctx);

  Its working fine for most of the songs.But some of the mp3 songs getting duration problem.For example if the song length is 2 mins if i seek the song to some position then finally song ends with 2 mins 10 seconds.I get this issue with only mp3 songs.Without seeking the same song ends with exact time. I am using ffmpeg 2.1 The some code working fine with ffmpeg 0.11.1 Please provide any information about this issue.

• Add metadata while converting MKV to MP3 with FFMPEG

  17 août 2020, par Elderhoard

  I am trying to convert MKV files to MP3, while adding metadata and album artwork through a batch file. I am generating a PNG through FFMPEG, then converting to MP3 while adding metadata, and finally adding the album artwork i got initially.

  


  I have tried adding the metadata while converting to MP3 and while adding the artwork to no avail. I read something about it flushing the buffer too quickly but thought I might be able to get around it by adding it while converting it.

  


  Individually, all parts work, but I can't get it to add the title and artist to the metadata, or at least in a place where VLC can read it. any suggestions ?

  


  @echo off
::Extracts a PNG thumbnail 
for %%A in ("*.mkv") do (ffmpeg -ss 30 -i "%%A" -qscale:v 4 -frames:v 1 "%%~nA.png")

::Convert from MKV to MP3 and adds title and artist based on file name delimited by "-" eg Metallica - Enter Sandman.mkv
SETLOCAL ENABLEDELAYEDEXPANSION
for %%A in ("*.mkv") do (
    set filename=%%~nA
    set artist=
    set song=
    echo "!filename!"

    for /F "tokens=1,2 delims=-" %%G in ("!filename!") do (
        set artist="%%G"
        set song="%%H"
        echo !artist!
        echo !song!
    )

    echo !song! by !artist!

    ffmpeg -i "%%A" -b:a 192K -id3v2_version 4 -write_id3v2 1 -metadata title="%song%" -metadata artist="%artist%" -flush_packets 0 -vn "%%~nA.mp3"
)

::Add Artwork to MP3
for %%A in ("*.mp3") do (ffmpeg -i "%%A" -i "%%~nA.png" -map 0:0 -map 1:0 -c copy -id3v2_version 3 "UPDATED%%~nA.mp3")
