ffmpeg custom buffer sink filter
25 novembre 2018, par NadavRubEnvironment
- Ubuntu 18.04
- C++
- ffmpeg 3.4 (git master)
- ffmpeg is used as a shared lib (InProc) via the C++ API
Use-case
- Per this link I am trying to use the ’avfilter_graph_*’ APIs to create ffmpeg graph
- I would like the graph output to be sent out to my custom code ( part of the hosting application )
Considered implementations
- [A] Implement a custom sink filter ( part of libavfilter ) to implement my custom logic
- [B] Implement a custom sink filter to grab the output samples and send them out to my application ( something similar to DShow SampleGrabber )
Problem at hand
With either of the above mentioned approaches the ffmpeg code has to be modified, and this impose an overhead in supporting future ffmpeg releases
I wonder if there is any straight forward approach for an external ( hosting ) application to grab the graph output w/ minimal copying of the payload.
Is there any way to use a custom AVIOContext to achieve that ? can I construct a graph connected to an output AVIOContext ? can I create a custom filter implemented in a module external to libavfilter and associate it w/ the graph using ’AVFilterContext’ ?
