2d59873fc1 fftools/ffmpeg_demux: add logging for -dump_attachment 
Makes it more clear what was written where.

63e4e8e4f4 fftools/ffmpeg_demux: forward errors from dump_attachment() instead of aborting 
Also, check the return code of avio_close().

ff0160cb37 fftools/ffmpeg_demux: drop a redundant avio_flush() 
It is immediately followed by avio_close(), which is documented to flush
the buffers.

e89a6d1089 fftools/ffmpeg_dec: move InputStream.prev_sub to Decoder 
It does not need to be visible outside of decoding code.

1adad44fc7 fftools/ffmpeg_dec: move InputStream.hwaccel_pix_fmt to Decoder 
It is purely decoder-internal state.

98766dbbd7 fftools/ffmpeg_demux: move the loop out of add_input_streams() 
Make the function process just one input stream at a time and save an
indentation level. Also rename it to ist_add() to be consistent with an
analogous function in ffmpeg_mux_init.

c7a05ac117 fftools/ffmpeg_demux: do not set AVCodecContext.framerate 
For decoding, this field is used by the decoder to export information
to the caller; it does not make sense for the caller to set it.

f8abab673c fftools/ffmpeg: move sub2video handling to ffmpeg_filter 
Make all relevant state per-filtergraph input, rather than per-input
stream. Refactor the code to make it work and avoid leaking memory when
a single subtitle stream is sent to multiple filters.

20cacfe493 fftools/ffmpeg: rework setting sub2video parameters 
Set them in ifilter_parameters_from_dec(), similarly to audio/video
streams. This reduces the extent to which sub2video filters need to be
treated specially.

4e96a71626 fftools/ffmpeg_demux: log discontinuity warnings to stream context 
Allows simplifying the log message.

6abb4a28ef fftools/ffmpeg: add InputStream.index 
This allows to avoid access to the underlying AVStream in many places.

cad59cccaf fftools/ffmpeg_dec: move timestamp estimation state to Decoder 
It is purely internal to decoding.

5b05e9e32a fftools/ffmpeg_dec: move InputStream.pkt to Decoder 
It is purely internal to decoding.

dadeb28e25 fftools/ffmpeg_dec: add decoder private data 
Move InputStream.decoded_frame to it.

Analogous to what has been previously done for all the other major
components.

335688a3d3 fftools/ffmpeg_demux: skip unused/attachment streams in final stats

6ee57fd2b6 fftools/ffmpeg_demux: only print demuxing stats if demuxing actually started 
If the transcoding process never got to reading any packets from this
input then printing stats is just pointless noise.

4cec5ffc45 fftools/ffmpeg: rework handling -max_error_rate 
Replace the decode_error_stat global with a per-input-stream variable.
Also, print an error message when the error rate is exceeded.

65f3d042a6 fftools/ffmpeg_demux: disallow using disabled input streams 
This is less ad-hoc than checking explicitly in every place that binds
an input stream to a filter or output.
 2023-05-22 17:10:44 +02:00

dfa29ba955 fftools/ffmpeg: return error codes from ist_*_add() 
Will be useful in future commits.

ede6794d6a fftools/ffmpeg_filter: split finding an unused stream into a function 
Avoids filtering code from digging in demuxer internals.

de6d60117e fftools/ffmpeg_demux: stop logging to demuxer context 
Only the demuxer itself should do that.

c5d77dcbf1 fftools/ffmpeg_demux: move InputFile.ts_offset_discont,last_ts to private data 
They are no longer used outside of ffmpeg_demux.

ab223a4d8c fftools/ffmpeg: stop accessing input format from decoding code 
Export the corresponding flag in InputFile instead. This will allow
making the demuxer AVFormatContext private in future commits, similarly
to what was previously done for muxers.

9429624a76 fftools/ffmpeg: move discarding unused programs to ffmpeg_demux 
This is a more appropriate place for this code.

f9657b7443 fftools/ffmpeg: simplify tracking -readrate start time 
There is no point in having a per-stream wallclock start time, since
they are all computed at the same instant. Keep a per-file start time
instead, initialized when the demuxer thread starts.

6b0c984f0d fftools/ffmpeg_demux: move InputStream.streamcopy_needed to private data

2b99c6bfd5 fftools/ffmpeg: move post-demux packet processing to ffmpeg_demux 
That is a more appropriate place for this code and will allow hiding
more of InputStream.

The value of repeat_pict extracted from libavformat internal parser no
longer needs to be trasmitted outside of the demuxing thread.

Move readrate handling to the demuxer thread. This has to be done in the
same commit, since it reads InputStream.dts,nb_packets, which are now
set in the demuxer thread.

09c686788e fftools/ffmpeg: attach InputStream.dts to demuxed packets when needed 
This way computing it and using it for streamcopy does not need to
happen in sync. Will be useful in following commits, where updating
InputStream.dts will be moved to the demuxing thread.

abf9532bda fftools/ffmpeg_demux: move preparing DemuxMsg to separate function 
Will be useful in following commits, which will move more code into this
function.

2d43c23b81 fftools/ffmpeg: discard packets for unused streams in demuxing thread 
Avoids the pointless overhead of transferring them to the main thread.
