Version 8.0.9.1

No issues.

Version 8.0.9.0

Extra PNG images may be generated if both the framerate and PNG filter are used in conjunction. As a workaround, it is recommend to not use the framerate filter if also using the PNG filter. Tthe source framerate will be used in this case. [Fixed in 8.0.9.1]

Version 8.0.8.0

  1. There is an issue when applying the resample filter that results in a crash when the input file already matches the specified sample rate/channels. This should be fixed in a patch release which is due sometime in the near future.

    The current workaround is to selectively apply the resample filter. One can check the input sample rate/channels with audio_options_GetSamplingrate() or audio_options_GetStereo() respectively, after calling SetInputFile.

    [Updated 2007-03-07]
    Please note this workaround will not work for files with no audio track.

    [Fixed in 8.0.8.1]

  2. There is an issue that results in an endless loop if the set framerate is greater than the source frame rate. This should be fixed in a patch release which is due sometime in the near future. The current workaround is to selectively apply the framerate filter. One can check the input framerate video_options_GetVideoFramerateAsDouble after calling SetInputFile. Or, one may want to use FE2_FRAMERATE_DECIMATE instead of trying to lower the framerate. [Fixed in 8.0.8.1]

Version 8.0.6.0

  1. Some MP4 files may have cropped output. This is not a rescaling issue but rather a bug in MEncoder that misinterprets the input dimensions. MPlayer shares the same problem.
  2. When re-sampling the audio (using FE2_FILTER_RESAMPLE or audio_options_SetSamplingrate()), there is an issue with out-ranging that causes an undesirable "scratching" or "crackling" noise for high frequencies. [Fixed in 8.0.7.0]
