From ea46b45e9c5475a62d37c9d79fe0ae038a04bdef Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Tue, 17 Mar 2020 22:31:47 +0100 Subject: [PATCH] avcodec/bsf: Beautify log messages from bitstream filters Up until now, the name of every AVBSFContext for logging purposes was "AVBSFContext", so that the default logging callback produced output like "[AVBSFContext @ 0x55813bae92c0] Extradata". This has been changed to "[trace_headers @ 0x60a000000700] Extradata" by adding an item_name- function to the AVClass for bitstream filters. Furthermore, the correct category has been set so that the introductory part before the actual message (everything before "Extradata" in the above examples) are displayed in a different colour than the rest.
