These are quite different issues, with completely different solutions.
For the case where it doesn't actually play past the original file size,
the solution is to simply double-check once the endpos is reached (or
rather, just never use it except as a hint at all).
That is advisable in general since with streams it can happen that the original
size indication isn't right anyway.
The OSD on the other hand is completely different.
For example it will only affect certain demuxers, in combination with
certain stream types.
These demuxers do have the issue that their time estimate is complete
So for example, the MOV, MKV, ... demuxers are not affected.
Even the TS demuxer is not affected when it is used as part of playing
In addition, since it is only for the OSD it is not a good idea to
update it on every read - updating maybe once per second should be
For the -PS demuxer it would require even more work, since that one
uses endpos to find and estimate the final time stamp, and thus get
Just updating endpos won't help one bit.
So while making the OSD work properly in this case would be nice,
a good solution isn't easy and it doesn't seem all that important to.
If someone wants to work on it I'll be happy to help out, but I'm fairly
certain it won't be done on one afternoon or so.
