Long mp4 files (duration > 12hrs) are rejected by the media player.


Found the following check in the gstreamer (qtdemux.c:5382):

  if (stream->n_samples >=
      QTDEMUX_MAX_SAMPLE_INDEX_SIZE / sizeof (QtDemuxSample)) {
    GST_WARNING_OBJECT (qtdemux, "not allocating index of %d samples, would "
        "be larger than %uMB (broken file?)", stream->n_samples,
        QTDEMUX_MAX_SAMPLE_INDEX_SIZE >> 20);

That means the gstreamer rejects streams which have more than QTDEMUX_MAX_SAMPLE_INDEX_SIZE / sizeof (QtDemuxSample) = 50 * 1024 * 1024 / 32 = 1638400 samples.
The file supplied 1861369 samples, that's why it couldn't be loaded.

Thus we have unreasonable file length limitation: even if there is enough memory to allocate for a sample table gstreamer rejects such media assuming that the 'file is broken'.
