#800 No Frame Rate Reported

[Matthew Carter]

Hi,

Since v0.7.59 onwards some MKV files do not report a frame rate (particularly ones created in Handbrake 0.9.9). v0.7.58 is the last version that reports the frame rate correctly.

I presume it may relate to this change in v0.7.59:

Matroska: Trying to better detect VFR streams, frame rate was wrong in case of interlaced content.

Thanks

Thanks

I checked your file, I have the following time codes for video:
0
41
83
142
183
225
267
308
350

All time code have a 41-42 ms of difference, which should be normal, but one frame duration is 59 ms (83 to 142), so I detect it as variable frame rate and I don't show the frame rate.
why has 1 frame a duration of 59 ms?

I have some issues with MKV frame rate detection, but for this file, from my point of view, there is a bug in Handbrake if you requested a constant frame rate, and MediaInfo reports correctly.

I new versions, I try to detect such weird time codes, it is my goal to detect that. If I am wrong, I am ready to change my code, but I need a proof that the time code I read are wrong (and I need the time codes you get and the tool you used).
