Deal with this by storing the final file size before closing the file. --- fftools/ffmpeg.c | 13 ------------- fftools/ffmpeg_mux.c | 16 +++++++++++++++- 2 files changed, 15 insertions(+), 14 deletions(-) diff --git a/fftools/ffmpeg.c b/fftools/ffmpeg.c index f28cc17f51..4f5c2cc49a 100644 --- a/fftools/ffmpeg.c +++ b/fftools/ffmpeg.c @@ -4348,7 +4348,6 @@ static int transcode_step(void) static int transcode(void) { int ret, i; - AVFormatContext *os; OutputStream *ost; InputStream *ist; int64_t timer_start; @@ -4417,18 +4416,6 @@ static int transcode(void) /* dump report by using the first video and audio streams */ print_report(1, timer_start, av_gettime_relative()); - /* close the output files */ - for (i = 0; i < nb_output_files; i++) { - os = output_files[i]->ctx; - if (os && os->oformat && !(os->oformat->flags & AVFMT_NOFILE)) { - if ((ret = avio_closep(&os->pb)) < 0) { - av_log(NULL, AV_LOG_ERROR, "Error closing file %s: %s\n", os->url, av_err2str(ret)); - if (exit_on_error) - exit_program(1); - } - } - } - /* close each encoder */ for (i = 0; i < nb_output_streams; i++) { ost = output_streams[i]; diff --git a/fftools/ffmpeg_mux.c b/fftools/ffmpeg_mux.c index 3b322ecb71..13b5d2d220 100644 --- a/fftools/ffmpeg_mux.c +++ b/fftools/ffmpeg_mux.c @@ -35,6 +35,7 @@ struct Muxer { /* filesize limit expressed in bytes */ int64_t limit_filesize; + int64_t final_filesize; int header_written; }; @@ -318,6 +319,17 @@ int of_write_trailer(OutputFile *of) return ret; } + of->mux->final_filesize = of_filesize(of); + + if (!(of->format->flags & AVFMT_NOFILE)) { + ret = avio_closep(&of->ctx->pb); + if (ret < 0) { + av_log(NULL, AV_LOG_ERROR, "Error closing file %s: %s\n", + of->ctx->url, av_err2str(ret)); + return ret; + } + } + return 0; } @@ -374,7 +386,9 @@ int64_t of_filesize(OutputFile *of) AVIOContext *pb = of->ctx->pb; int64_t ret = -1; - if (pb) { + if (of->mux->final_filesize) + ret = of->mux->final_filesize; + else if (pb) { ret = avio_size(pb); if (ret <= 0) // FIXME improve avio_size() so it works with non seekable output too ret = avio_tell(pb); -- 2.33.0 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
