Andreas Rheinhardt	c1e439d7e9	avformat: Forward errors where possible 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.

Anton Khirnov	83548fe894	lavf: fix usage of AVIOContext.seekable It is supposed to be a flag. The only currently defined value is AVIO_SEEKABLE_NORMAL, but other ones may be added in the future. However all the current lavf code treats this field as a bool (mainly for historical reasons). Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.	8 years ago
Anton Khirnov	9200514ad8	lavf: replace AVStream.codec with AVStream.codecpar Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.	9 years ago

Justin Ruggles	ac3f8d317c	ape: calculate final packet size instead of guessing Calculates based on total file size and wavetaillength from the header. Falls back to multiplying finalframeblocks by 8 instead of 4 so that it will at least be overestimating for 24-bit. Currently it can underestimate the final packet size, leading to decoding errors.	13 years ago
