Each time init is called (i.e. for reinit on resolution change), the private context is a new instance. On first init we want mode="w" for each rawdump filter in the graph, but on reinit we want mode="a". How do we achieve this when every call to init passes a new private context instance. I am not very familiar with ffmpeg's programming API's, so maybe I'm missing something? > Regards, > > -- > Nicolas George _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
