Well, patches are usually welcome here if they add an useful feature. The double speed effect is probably caused by you saving the packets payloads but not their headers. The result is an elementary stream, it works more or less depending on the codec, and frequently lacks some information, especially timestamps, or at least timestamps recognized by the decoders. Timestamps problem => speed problem. If you want to contribute, you have to more or less follow these guidelines: - Work with the git head version. The 1.1 version you are using is ancient and no longer supported, your change would not work on it (there is no longer a pkt variable at this point). - Commit your change and use git to produce a proper patch proposal (git send-email or git format-patch). BUT: I do not think this feature is useful, at least as is: it has too many limitations, and I am pretty sure it can already be done in a different but more robust way. Most importantly, if ffplay is capable of playing the stream, then ffmpeg should be able to read and manipulate it, there are no real doubts about it. I suggest you go to the users mailing-list and try to get help making it work. If it works with ffmpeg, then we can see if your proposal still brings an useful enhancement; if it does not work, then we will endeavour to make it work. Regards, -- Nicolas George
