I think theres no reason to use the old one if the 64bit one is added. We could refrain from removing the old though for longer as it has no risk of breaking. But deprecation would notify users that we have something newer/better to replace it thx [...]

But deprecation > would notify users that we have something newer/better to replace it Well, actually av_get_frame_filename3 should be deprecated too soon, because users should not use these functions because they limit the file path to a fixed length. An AVBPrintf based replacement should be used instead in the long run. On the other hand that is a bit more work, so I am fine with the patch as is. Thanks, Marton

No, adding a function that will be obsolete from day 1 is not a good idea. Adding API is simple, but removing it takes years. So lets instead add one using AVBPrintf that will be definite.

Create a new av_get_frame_filename3() API which is just like the previous version but accepts a 64-bit integer for the "number" argument. This is useful in cases where you want to put the original PTS into the filename (which can be larger than 32-bits).
