6c6f13baf3 fftools/ffmpeg: return errors from find_codec_or_die() instead of aborting 
Rename the function to just find_codec().

26e1e80152 fftools/ffmpeg_opt: reimplement -streamid using a dictionary 
This does not require an arbitrary limit on the number of streams.

Also, return error codes from opt_streamid() instead of aborting.

c4b074676a fftools/ffmpeg_mux_init: avoid invalid memory access in set_dispositions() 
This function assumes AVMEDIA_* are always positive, while in fact it
can also handle AVMEDIA_TYPE_UNKNOWN, which is -1.

037d364797 fftools/ffmpeg_filter: move "smart" pixfmt selection to ffmpeg_mux_init 
This code works on encoder information and has no interaction with
filtering, so it does not belong in ffmpeg_filter.

249bca763d fftools/ffmpeg_mux_init: handle pixel format endianness 
When -pix_fmt designates a BE/LE pixel format, it gets translated into
the native one by av_get_pix_fmt(). This may not always be the best
choice, as the encoder might only support one endianness. In such a
case, explicitly choose the endianness supported by the encoder.

While this is currently redundant with choose_pixel_fmt() in
ffmpeg_filter.c, the latter code will be deprecated in following commits.

153cf85b24 fftools/ffmpeg_mux_init: fix an array declaration 
map_func is supposed to be an array of const pointer to function
returning int, not an array of pointer to function returning const int.

dff3a283cd fftools/ffmpeg: rework -enc_time_base handling 
Read the timebase from FrameData rather than the input stream. This
should fix #10393 and generally be more reliable.

Replace the use of '-1' to indicate demuxing timebase with the string
'demux'. Also allow to request filter timebase with
'-enc_time_base filter'.

20c42213ea fftools/ffmpeg_mux_init: drop an obsolete assignment 
This line was added in c30a4489b4 along with
AVStream.sample_aspect_ratio. However, configuring SAR for video
encoding is now done after this code (specifically in enc_open(), which
is called when the first video frame to be encoded is obtained), so this
line cannot have any meaningful effect.

dd44871eb9 fftools/ffmpeg_mux_init: improve of_add_programs() 
Replace duplicated(!) and broken* custom string parsing with
av_dict_parse_string(). Return error codes instead of aborting.

* e.g. it treats NULL returned from av_get_token() as "separator not
  found", when in fact av_get_token() only returns NULL on memory
  allocation failure

38a2fc2c29 fftools/ffmpeg_mux_init: move allocation out of prologue 
ost_add() has a very large variable declaration prologue, performing
"active" actions that can fail in there is confusing.

93e26a4db7 fftools/ffmpeg: handle -enc_time_base -1 during stream creation 
There is no reason to postpone it until opening the encoder. Also, abort
when the input stream is unknown, rather than disregard an explicit
request from the user.

c8a85d1b2f fftools/ffmpeg_mux_init: do not overwrite OutputStream.frame_rate for streamcopy 
The values currently written into it are not used after
streamcopy_init(), so it is better to confine them to that function.

57021a68d9 fftools/ffmpeg_mux: set stream duration after the timebase is certainly known 
Stop assuming the encoder knows the muxing timebase, which does not
always have to hold (e.g. due to bitstream filters).

da7ae627e1 fftools/ffmpeg_filter: always pass graph description to fg_create() 
Currently NULL would be passed for simple filtergraphs, which would
make the filter code extract the graph description from the output
stream when needed. This is unnecessarily convoluted.

09dd9c5f41 fftools/ffmpeg_filter: add filtergraph private data

to the filtergraph rather than the output stream.

0add05bd3a fftools/ffmpeg_mux_init: rename init_output_filter() to ost_add_from_filter() 
The previous name is misleading, because the function does not actually
initialize any filters - it creates a new output stream and binds a
filtergraph output to it.

6cace17b0d fftools/ffmpeg_mux_init: drop useless new_stream_{data,unknown} 
Their only function is checking that encoding was not specified for
data/unknown-type streams, but the check is broken because enc_ctx will
not be created in ost_add() unless a valid encoder can be found.

Add an actually working check for all types for which encoding is not
supported in choose_encoder().
