also remove unneeded commented-out full frame data debugging

We now require at least libmp3lame 3.98.3. lame_encode_buffer_interleaved() still doesn't work for mono, but it does not "die"; it just expects a stereo interleaved buffer.

it is already set in avcodec_alloc_frame()

This avoids reading any old data in the AVIOContext buffer after the seek, and indicates to the mpegts demuxer that we've seeked, avoiding continuity check errors. Signed-off-by:

This makes switching to encode2() simpler, because it allows us to know exactly how large should the output buffer be before we start writing into it.

Revert "swscale: update context offsets after removal of AlpMmxFilter." (commit a95e3fa9) and Revert "swscale: Remove some write-only variables related to alpha handling." (commit 9d03cb9f). They broke alpha handling - it's the evil inline asm that still uses that variable, so it's not truely write-only.

Enhance seeking by demuxing until the requested timestamp is reached within the segment selected by the seek code using the playlist info. Some mpegts streams don't have dts set for all packets though, this seeking method doesn't work well for that case. Signed-off-by:

This allows the following commit to extrapolate better dts for the first frame. Pts difference between the first two frames is reused as the difference between pts and dts of the first frame.

Apple ProRes Format Specifications mentions target data size for every frame, so make sure frame meets it. This also allows encoder to demand much smaller packet sizes for output.

The parser uses VLC tables initialized in vc1_common_init(), therefore we should call this function on parser init also. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

Return 0 means "please return the same data again", i.e. it causes an infinite loop. Instead, return an error. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

This prevents failed assertions further down in the packet processing where we require non-negative values for packet_size_left. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

Return 0 indicates "please return the same data again", i.e. it causes an infinite loop. Instead, return that we consumed the buffer if we finished decoding succesfully, or return an error if an error occurred. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

H263 in RTP can be packetized in two formats (RFC 2190, RFC 2429/4629). The former normally uses the static payload type 34, while the latter normally uses dynamic payload types with the SDP format names H263-1998 or H263-2000. Look for packets that don't look like proper RFC 2190 packets and switch to depacketizing them according to the new format if they match some heuristic criteria. Signed-off-by:
