pango: Create a new base class for all the elements This prevents the ugly hack where the text_sink pad template was only added for textoverlay but not for the subclasses. Also makes this work with the core change that made subclasses inherit the templates of their parent class.

pango: Add a property to compensate for display response time When measuring video latency, one mechanism involves taking a photo with a camera of two screens showing the test video overlayed with timeoverlay or clockoverlay. In these cases, if the display's pixel response time is crappy, you will see ghosting due to which it can be quite difficult to discern what the current timestamp being shown is. This commit adds a property that *also* shows the timestamp in a different (sequentially predictable) location every frame, which makes it easy to tell what the latest rendered timestamp is. For bonus points, you can also use the fade-time of the previous frame to measure with sub-framerate accuracy when the photo was taken, not just clamped to the framerate, giving you a higher precision latency value.

pango: Add a property to compensate for display response time When measuring video latency, one mechanism involves taking a photo with a camera of two screens showing the test video overlayed with timeoverlay or clockoverlay. In these cases, if the display's pixel response time is crappy, you will see ghosting due to which it can be quite difficult to discern what the current timestamp being shown is. This commit adds a property that *also* shows the timestamp in a different (sequentially predictable) location every frame, which makes it easy to tell what the latest rendered timestamp is. For bonus points, you can also use the fade-time of the previous frame to measure with sub-framerate accuracy when the photo was taken, not just clamped to the framerate, giving you a higher precision latency value.

* Compensate for display response time by doing a second text render in

*
* On all current displays, after a pixel is told to show a different color
* value, there is a "response time" after which the transition from the
* previous color to the new color is complete. On some displays this can
* take tens of milliseconds to complete, causing the previous frame's text
* render to overlap with the current frame's text render.
*
* This makes text renders that have the same position but change contents
* every frame impossible to use on displays with bad response times, such
* as when using clockoverlay and timeoverlay.
*
* Note that this is different from display lag/latency, which is an
* inherent property of the display and cannot be compensated for.

basetextoverlay: Don't miscalculate text running times When a new segment event arrives, it immediately updates the current stored segment, which was used for calculating the running time of the current text buffer for every passing video frame. This means a segment that arrives after the text buffer might get used to (mis)calculate the running times subsequently. Instead, calculate and store the right running time using the current segment when storing the buffer. Later the stored segment can get freely updated. This fixes the case where pieces of video and text streams are seamlessly concatenated and fed through the text overlay. Previously, it could lead to the current text buffer suddenly have a massive running time and blocking all further input.

In these cases, if the display's pixel response time is crappy, you will see ghosting due to which it can be quite difficult to discern what the current timestamp being shown is. This commit adds a property that *also* shows the timestamp in a different (sequentially predictable) location every frame, which makes it easy to tell what the latest rendered timestamp is. For bonus points, you can also use the fade-time of the previous frame to measure with sub-framerate accuracy when the photo was taken, not just clamped to the framerate, giving you a higher precision latency value.

This commit adds a property that *also* shows the timestamp in a different (sequentially predictable) location every frame, which makes it easy to tell what the latest rendered timestamp is. For bonus points, you can also use the fade-time of the previous frame to measure with sub-framerate accuracy when the photo was taken, not just clamped to the framerate, giving you a higher precision latency value.

basetextoverlay: Fix overlay never rendering again if width reaches 1px If text width ever reached 1px, for example after resizing the output window, the overlay would stop rendering and never return again. The 1px condition itself does not seem to make much sense here anyway. This was a chain of events: width reached 1, so the composition was set to NULL. Then, after resizing the output window, push_frame() was called but would not attempt to renegotiate because composition is NULL. This caused the width/height to never be updated again, as that only happens during negotiation, so the overlay was gone for good.

basetextoverlay: Fix clipping issues This patch uses the ink rectangle in order to compute the size of the surface require to render. It also correctly compute the transformation matrix as the ink_rect position might not be at 0, 0. Additionally, shadow_offset and outline_offset (which is in fact the diameter of a dot, not a really an offset) is now taken into account. Redundant matrix operation has been removed for the vertical rendering. Take note that the matrix operation in cairo are excuted in reverse order. https://bugzilla.gnome.org/show_bug.cgi?id=728636

Instead, calculate and store the right running time using the current segment when storing the buffer. Later the stored segment can get freely updated. This fixes the case where pieces of video and text streams are seamlessly concatenated and fed through the text overlay.
