* avformat: Avoid allocation for AVStreamInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.

* avformat: Forward errors where possibleAndreas Rheinhardt2019-12-12
| | | | | | | | | | It is not uncommon to find code where the caller thinks to know better what the return value should be than the callee. E.g. something like "if (av_new_packet(pkt, size) < 0) return AVERROR(ENOMEM);". This commit changes several instances of this to instead forward the actual error.
