[FFmpeg-devel] Palette support broken when using avcodec_copy_context

[Jean-Daniel Dupas]

Hello,

I have a problem with the palette support. Actually, the palctrl field in AVCodecContext is allocated and free by the demuxers (mov.c for example).
If you use avcodec_copy_context, this field is set to NULL and so, the decoder crash when it try to access it. 
As this field is managed by the demuxer, it's not possible to copy it in avcodec_copy_context, else it will leaks (the demuxer will never free it).

Has someone any idea about how to fix that ?
