* lavc: handle hw_frames_ctx where necessaryAndrey Turkin2016-05-25
| | | | | | | avcodec_copy_context() didn't handle hw_frames_ctx references correctly which could cause crashes. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavc: document that avcodec_close() should not be usedAnton Khirnov2016-05-23
| | | | | | | We cannot deprecate it until the new parser API is in place, because of the way libavformat works. But the majority of the users can already simply replace it with avcodec_free_context(), which will simplify the transition once it is finally deprecated.
* lavc: deprecate avcodec_get_context_defaults3()Anton Khirnov2016-05-23
| | | | | | | | | This function is supposed to "reset" a codec context to a clean state so that it can be opened again. The only reason it exists is to allow using AVStream.codec as a decoding context (after it was already opened/used/closed by avformat_find_stream_info()). Since that behaviour is now deprecated, there is no reason for this function to exist anymore.
* lavc: deprecate avcodec_copy_context()Anton Khirnov2016-05-23
| | | | | | | | | Since AVCodecContext contains a lot of complex state, copying a codec context is not a well-defined operation. The purpose for which it is typically used (which is well-defined) is copying the stream parameters from one codec context to another. That is now possible with through the AVCodecParameters API. Therefore, there is no reason for avcodec_copy_context() to exist.

* nvenc: De-compensate aspect ratio compensation of DVD-like content.Philip Langdale2016-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For reasons we are not privy to, nvidia decided that the nvenc encoder should apply aspect ratio compensation to 'DVD like' content, assuming that the content is not BT.601 compliant, but needs to be BT.601 compliant. In this context, that means that they make the following, questionable, assumptions: 1) If the input dimensions are 720x480 or 720x576, assume the content has an active area of 704x480 or 704x576. 2) Assume that whatever the input sample aspect ratio is, it does not account for the difference between 'physical' and 'active' dimensions. From these assumptions, they then conclude that they can 'help', by adjusting the sample aspect ratio by a factor of 45/44. And indeed, if you wanted to display only the 704 wide active area with the same aspect ratio as the full 720 wide image - this would be the correct adjustment factor, but what if you don't? And more importantly, what if you're used to lavc not making this kind of adjustment at encode time - because none of the other encoders do this! And, what if you had already accounted for BT.601 and your input had the correct attributes? Well, it's going to apply the compensation anyway! So, if you take some content, and feed it through nvenc repeatedly, it will keep scaling the aspect ratio every time, stretching your video out more and more and more. So, clearly, regardless of whether you want to apply bt.601 aspect ratio adjustments or not, this is not the way to do it. With any other lavc encoder, you would do it as part of defining your input parameters or do the adjustment at playback time, and there's no reason by nvenc should be any different. This change adds some logic to undo the compensation that nvenc would otherwise do. nvidia engineers have told us that they will work to make this compensation mechanism optional in a future release of the nvenc SDK. At that point, we can adapt accordingly. Signed-off-by: Philip Langdale <philipl@overt.org> Reviewed-by: Timo Rothenpieler <timo@rothenpieler.org> Signed-off-by: Anton Khirnov <anton@khirnov.net>

| | | | | | | There is no real advantage to listing some codecs or subsystems separately simply because they are somehow "hw-accelerated", on the contrary it makes them harder to find than in a plain alphabetically ordered list.

* mmaldec: limit internal bufferingwm42016-04-30
| | | | | | | | | | | | | | | | | | This uses a new MMAL feature, which limits the number of extra frames that can be buffered within the decoder. VIDEO_MAX_NUM_CALLBACKS can be defined as positive or negative number. Positive numbers are absolute, and can lead to deadlocks if the user underestimates the number of required buffers. Negative numbers specify the number of extra buffers, e.g. -1 means no extra buffer, (-1-N) means N extra buffers. Set a gratuitous default of -11 (N=10). This is much lower than the firmware default, which appears to be 96. This is backwards compatible, but needs a symbol only present in newer firmware headers. (It's an enum item, so it requires a check in configure.) Signed-off-by: Anton Khirnov <anton@khirnov.net>
