Passing udp unix socket as input to ffmpeg -


i know ffmpeg able receive input unix socket:

ffmpeg -i unix://path-to-socket ...

problem once changing socket type sock_dgram instead of sock_stream in server code, ffmpeg not able receive data , error printed:

unix://path-to-socket: protocol wrong type socket

looking @ socket documentation on ffmpeg's site following options can applied:

  • timeout: timeout in ms.
  • listen: create unix socket in listening mode.

which not relevant declaring socket type.

ls configuring unix socket sock_dgram possible?

thanks,

joey.

the documentation incomplete. in ffmpeg/libavformat/unix.c,

static const avoption unix_options[] = {     { "listen",    "open socket listening",             offset(listen),  av_opt_type_bool,  { .i64 = 0 },                    0,       1, ed },     { "timeout",   "timeout in ms",                         offset(timeout), av_opt_type_int,   { .i64 = -1 },                  -1, int_max, ed },     { "type",      "socket type",                           offset(type),    av_opt_type_int,   { .i64 = sock_stream },    int_min, int_max, ed, "type" },     { "stream",    "stream (reliable stream-oriented)",     0,               av_opt_type_const, { .i64 = sock_stream },    int_min, int_max, ed, "type" },     { "datagram",  "datagram (unreliable packet-oriented)", 0,               av_opt_type_const, { .i64 = sock_dgram },     int_min, int_max, ed, "type" },     { "seqpacket", "seqpacket (reliable packet-oriented",   0,               av_opt_type_const, { .i64 = sock_seqpacket }, int_min, int_max, ed, "type" },     { null } };

it handles stream=1, datagram=1, seqpacket=1, or type=#, # integer value of desired socket type (sock_stream=1, sock_dgram=2, sock_seqpacket=5).

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
