| | | | | | | | | | | | | | | | | | Main use-case is proxying avio through a foreign I/O layer and a custom AVIO context, without losing latency and performance characteristics. Signed-off-by: Luca Barbato <lu_zero@gentoo.org> Merged from Libav commit 173b56218f39c64.
* | avio: add a destructor for AVIOContextAnton Khirnov2017-09-01
| | | | | | | | | | | | | | | | Before this commit, AVIOContext is to be freed with a plain av_free(), which prevents us from adding any deeper structure to it. (cherry picked from commit 99684f3ae752fc8bfb44a2dd1482f8d7a3d8536d) Signed-off-by: James Almer <jamrial@gmail.com>

* | ffmpeg options: Enable trailing ? for map_channelpkviet2017-08-25
| | | | | | | | | | | | | | | | | | | | | | The -map option allows for a trailing ? so that an error is not thrown if the input stream does not exist. This capability is extended to the map_channel option. This allows a ffmpeg command not to break if an input channel does not exist, which can be of use (for instance, scripts processing audio channels with sources having unset number of audio channels).

* | vaapi_encode: Move quality option to common codeMark Thompson2017-08-20
| | | | | | | | | | | | | | | | | | | | | | Use AVCodecContext.compression_level rather than a private option, replacing the H.264-specific quality option (which stays only for compatibility). This now works with the H.265 encoder in the i965 driver, as well as the existing cases with the H.264 encoder. (cherry picked from commit 19388a7200e5d99c703271f05dba1c806720e808)

* | imgutils: add function to clear an image to blackwm42017-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Black isn't always just memset(ptr, 0, size). Limited YUV in particular requires relatively non-obvious values, and filling a frame with repeating 0 bytes is disallowed in some contexts. With component sizes larger than 8 or packed YUV, this can become relatively complicated. So having a generic function for this seems helpful. In order to handle the complex cases in a generic way without destroying performance, this code attempts to compute a black pixel, and then uses that value to clear the image data quickly by using a function like memset. Common cases like yuv410p10 or rgba can't be handled with a simple memset, so there is some code to fill memory with 2/4/8 byte patterns. For the remaining cases, a generic slow fallback is used.

* | avfilter: Add blue and violet noise generation filtersGeorge Boyle2017-07-19
| | | | | | | | | | | | | | | | | | For the blue and violet noise, I took the pink and brown noise respectively and subtracted the offsets instead of adding them. When I eyeball the frequency spectrum of the resulting outputs it looks correct to me, i.e. the blue graph appears to be a mirror image of the pink, and the same can be said of the violet and the brown. I did not do anything else to confirm the correctness.
