* avcodec/bsf: Beautify log messages from bitstream filtersAndreas Rheinhardt2020-03-21
| | | | | | | | | | | | | | | | 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.

* avcodec/bsf: make sure the AVBSFInternal stored packet is reference countedJames Almer2018-03-23
| | | | | | | | | | | | | | | | | | Some bitstream filters may buffer said packet in their own contexts for latter use. The documentation for av_bsf_send_packet() doesn't forbid feeding it non-reference counted packets, which depending on the way said packets were internally buffered by the bsf it may result in the data described in them becoming invalid or unavailable at any time. This was the case with vp9_superframe after commit e1bc3f4396, which was then promptly fixed in 37f4a093f7 and 7a02b364b6. It is still the case even today with vp9_reorder_raw. With this change the bitstream filters will not have to worry how to store or consume the packets fed to them. Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: James Almer <jamrial@gmail.com>
